Terms and Conditions

Shipping and Delivery

Same Day Shipping by 2pm & Delivery Date Estimate.

NOTICE: We will continue to do our best to provide same-day shipping for orders placed by 2 pm, but due to challenges related to the pandemic, including staff shortages, we encourage customers to place orders as early in the day as possible. We are still striving to get all orders placed before 2:00 pm shipped the same day, but we cannot guarantee it at this time. Orders shipping by air will have priority over those shipping by ground.

For select online items, NAASCO provides same-day shipment of in-stock items if the order is received before 2 pm local time using a carrier of our choice. Items in the Shopping Cart will display the stock status and an expected ship day based on the shipping method chosen when “Default” origin is used. This date will factor in the time the order is placed as well as the status in the origin warehouse and destination zip code. Carrier delays due to weather and other factors outside our control remove NAASCO’s responsibility from the quoted delivery date. On days when order volume exceeds operation capacity, for example, after holidays or closures, same-day shipping cannot be guaranteed, although we will do everything possible to meet our goal. Delivery dates will depend on the exact time of order placement, so the true expected date will be referenced on the Order Confirmation screen. On Backordered items, Out of Stock items, Special Orders, Dropship items, and Non-stocking Products, we will provide an expected ship date if the item is on order from the supplier. However, these dates are expected delivery dates of Pos, and we cannot guarantee the items will be delivered within that window as factory delays and other elements outside of our control can delay the order.

Ship and Backorder

Orders shipping within the lower 48 USA are defaulted to ship and backorder. If you would like your order held and shipped in one package, please note in the Special Instructions box that you would like the order to “Ship Complete.” If you have a preferred ship date other than the date of order placement, please note that in the Special Instructions as well. The customer can select the “Ship and Backorder” option is in the Shopping Cart (The customer will be charged freight on both shipments). Special instructions or credit card declines may delay the fulfillment of the order.

Shipping Charges

Shipping charges provided online are calculated from the weights and dimensions of the box(es) required to ship all the items on the order. The system will look for the optimal fulfillment logic to distribute the items to the required warehouse(s). Shipping rates quoted online will be applied to the order at invoicing. The exception to this is the Ship and Backorder option for International shipments, in which case an estimate is provided, and the actual shipping charge will be calculated when invoicing each shipment. If the shipping charges seem incorrect for the items on order, please use the Special Instructions box in the Shopping Cart to request a manual freight quote from a staff member. We will evaluate the contents of the order, origin warehouse(es), and destination and provide via email a new shipping quote. Please keep in mind that the order will be held until you confirm the new shipping estimate provided by the staff member. If a split shipment/backorder is required to complete the order, a different carrier, such as USPS, may be used if the shipment’s contents are lightweight and of small value. Additional freight charges may be applied when invoicing on the product(s) that are backordered due to manufacturing or supply chain delays that are of no fault of NAASCO.

Shipping costs for certain product mixes or types cannot be calculated online. Examples of these types of products are wood, metal, oversized items, made-to-order items, and other specialty cut materials. When this is the case, the shipping costs will be calculated at the invoicing station. The shipping costs charged will be based on the exact weights, and dimensions of the actual box(es) used to ship the order. This condition will be referenced in the shopping cart by a note that says, ‘We are unable to accurately estimate the shipping costs of your order. Shipping Costs will be Calculated at the Time of Shipping’. If you would like a manual estimate before the order ships, please use the Special Instructions box in the Shopping Cart to request a manual freight quote from a member of our staff. We will evaluate the contents of the order, origin warehouse(es), and destination and provide via email a new shipping quote. Please keep in mind that the order will be held until you confirm the new shipping estimate provided by the staff member.

Some oversize charges which were not able to be predicted online will be assessed at the time of shipment. Packages over 48 inches in length will be assessed an additional handling fee as declared in the carrier’s service guide. All packages will be charged at the greater of actual or dimensional weight. According to the carrier service guide, packages over 96 inches in length or 130 inches in length and girth will also be assessed a fee for exceeding the maximum package size, in addition to being billed at a 90lb oversize rate. Dimensional weight is calculated as the total cubic inches of a package divided by a dimensional weight factor (domestic US is 194, outside US is 166). Some oversized items can be cut for shipping. If you think this might apply, please return to your shopping cart and include cutting instructions in the Special Instructions box.

Hazardous items may be assessed as an additional hazardous shipping charge for each package containing hazardous materials. This fee, if it applies, will be added to the calculated freight charge. Shipping charges for the phone in sales are calculated at the time of shipping based on the weights and dimensions of the box(es) used to ship the order. If you would like an estimate, just ask your friendly NAASCO sales agent, and they will provide you with one.

Free Shipping on Orders Over $350

Most orders over $350 merchandise value of the in-stock item(s), shipping within the 48 contiguous United States and Alaska, will be shipped prepaid, with NAASCO paying the shipping cost. If your order qualifies for free shipping, it will be offered as a shipping method in the Shopping Cart. ‘Free Ground’ must be selected as the shipping method for the order to ship prepaid. Any other shipping selection will bill the quoted amount when invoicing. Please inquire at the time of order if you have questions regarding the free shipping policy as it applies to your order. NAASCO will determine what vendor is used to provide Free Shipping orders when offered.  Free shipping must be requested at the time of order with your salesperson on the phone in orders. Orders placed online must use the ‘Default’ origin selection to qualify for Free Shipping. 

International Shipping

Our customer service team is more than happy to assist you in placing and processing your order for international shipment. Please note the following guidelines for placing an international order. You may place your order using the e-commerce site or contact us directly at [email protected] or by calling us at 1-631-399-2244. 

To economize on the shipping costs, International orders are generally shipped complete unless otherwise advised by the customer. We utilize UPS, FedEx, and Air Parcel Post for most international shipments. Shipments by UPS and FedEx are highly recommended because of the excellent traceability of the shipments. Parcel post traces are very time-consuming and unreliable. We cannot be responsible for shipments made by Parcel Post. Our international department also utilizes the services of many other air and sea carriers. Should the services of a freight forwarder be necessary, we can work with one who is familiar with our service or with one of your choices to meet all your shipment requirements.

All freight, duty, and customs charges are the customer’s responsibility. If NAASCO is billed these charges on your behalf, you agree to be billed by NAASCO for these charges. It is the responsibility of the recipient to clear the shipment through their local customs and brokerage and pay all import fees, such as customs and duties. NAASCO does not accept responsibility for any shipments that are abandoned due to the recipient’s failure to pay import fees. NAASCO will deduct the cost of freight, return freight, and any applicable import fees for any shipments that are returned due to refusal by the recipient to pay local import fees in the original destination country.

Payment Information

Credit / Debit Cards

NAASCO accepts all major credit cards, including Visa, Mastercard, American Express, and Discover. We do not accept Diner’s Club. Online orders must be completed on one credit card; however, split credit card payments are accepted by phone at 1-631-399-2244 or email at [email protected].

We prefer first-time orders to ship to the same address as the credit card billing address. If the order is routed to management for approval, we will verify the address with the customer’s bank. The billing address must match exactly before the order can be processed for shipment. Additional forms of identification may be requested to verify the order’s legitimacy. If we cannot confirm the validity of the cardholder, we may request a wire transfer to complete the sale.

If the customer requests to ship to another address, we will first verify the billing address. If this address is correct, we will verify that the shipping address is also on file with the bank. If it is not, we request that the customer call his bank and advise them to add the alternate address to his file for verification. The customer will then notify us that the address is on file with the bank. We will then call the bank and confirm. Once confirmed, the order will be released to ship. We may also, at our discretion, attempt to contact the cardholder by phone to confirm the order. If the alternate address is a hotel, we reserve the right to decline shipment until payment is received in full in advance and we confirm that the customer’s name is registered with the hotel. We reserve the right to insist that any first-time order ship to a verified billing address only.

We reserve the right to request authorization on your credit card for the order amount at the time of order. When the order ships, we will settle and collect the amount of the order, including but not limited to the merchandise, applicable taxes, freight, and/or ancillary charges, and any authorized amounts over the settled amount will be released. If your order cannot ship before the authorization expires, you agree to allow us to settle that authorization to hold the parts for you until the order is ready for shipment. You agree to hold NAASCO harmless for any costs you incur due to over-limit or insufficient funds as assessed by your credit card company or bank. Special orders or dropship items are settled when the purchase order to our supplier is issued.


Company checks are accepted for all orders by phone at 1-631-399-2244 or by email at [email protected].  Once the check clears, the items will ship.

Wire Transfer

You may place an order by phone or email and pay by wire transfer. First, contact our sales staff with your parts list and destination address. They will then send you a proforma quote, including all applicable charges. The banking details for sending the wire transfer will be on the proforma quote. Once we receive the funds, we will release your order for shipment.

Open Accounts (Net Terms)

NAASCO has long served many companies and government agencies on an open account basis. Established companies can apply for an open account by submitting a credit application including all company data and at least three business references and bank information. Credit application forms are available on request. Open account terms are net 30 days after the invoice date unless otherwise agreed upon by NAASCO.

Pricing Policy

Pricing Updates

Although we update pricing for the online catalog daily, occasionally, there may be a price discrepancy between the price online and the actual current price. If there is a price discrepancy that we identify when we process the order, we will notify you by email so that you are aware of any changes. There may be a variety of reasons for this.

Return Policy

Before returning any product, contact NAASCO to determine if an RMA (Return Merchandise Authorization) number and return shipping instructions are required to process a return.   Submitting an RMA request does not automatically constitute authorization. This can be done by calling 1-631-399-2244 or by email at [email protected].

It is the customer’s responsibility to verify application eligibility before starting the installation.  NAASCO is not responsible for parts installed incorrectly due to suggested applicability. It is the responsibility of the purchaser/installer to verify eligibility before installation.

International Orders

Our inside sales team is more than happy to assist you in placing and processing your order for international shipment. Please note the following guidelines for placing an international order. Correspondence should be sent in English or Spanish to expedite service.

Requests for quotation are processed within 72 hours unless additional research is required on a product. A quotation is processed as a proforma invoice for all overseas customers. A proforma invoice is not considered an order until funds are received to process the order. Actual freight charges may differ from a freight quote or estimate provided by a freight carrier.

First time orders are preferably received by fax, e-mail, or website to ensure correct notation of name and billing and shipping information. Please note the information on 8130 forms in the following paragraphs. If 8130 forms are required, we must be notified at the time the order is placed so that we may special order the documentation.

To economize on the shipping costs, International orders are generally shipped complete unless otherwise advised by the customer. We utilize DHL, UPS, FedEx, and Air Parcel Post for most international shipments. Shipments by DHL, UPS, and FedEx are highly recommended because of the excellent traceability of the shipments. Parcel post traces are very time-consuming and unreliable. We cannot be responsible for shipments made by USPS Parcel Post. Our international department also utilizes the services of many other air and sea carriers. Should the services of a freight forwarder be necessary, we can work with one who is familiar with our service or with one of your choices to meet your shipment requirements.

All freight, duty, and customs charges are the customer’s responsibility.

Preferred methods of payment are credit cards (American Express, Visa, Mastercard, Discover) and by bank transfers. There is an additional $35 service charge for bank transfers. When making a bank transfer, please fax a copy of your transfer along with your order request to ensure the accurate allocation of funds. Please note that if payment is made by bank transfer, there is an approximate 7-day delay before funds are confirmed and allocated.

Always remember to furnish your complete communications information on your correspondence so that we may respond to your requests promptly. We welcome your orders and look forward to being part of your team during your entire project.

HAZMAT SHIPMENTS: A fee is charged on all international shipments containing hazardous materials. This fee covers special packaging, documentation, and certification requirements for hazmat orders shipping to customers outside the United States.

Other Conditions of Sale

Product Photography / Images

Product photos shown may represent the product type or be for illustration purposes only and may not be an exact representation of the product delivered. Due to the number of individual SKUs offered, it would be an impractical task to take and upload individual product photography for every single item, and in any case, NAASCO relies on the manufacturer of the product to provide photography for their products. We always recommend ordering by the model number and application of a product and not purely by the photo. Please contact a NAASCO sales representative if you would like confirmation that what you are ordering will match the website or catalog photo/imagery.

Ship and Backorder

Our default shipping option will allow us to ship all in-stock products to you immediately from the nearest geographic warehouse with inventory and backorder any items which are not in stock. The items that did not ship will be sent from the next closest warehouse with inventory. If we do not have any product inventory, we will ship the parts as soon as any warehouse receives stock from our suppliers. NAASCO pays the freight on most backorder shipments within the lower 48 states (except oversize packages, hazardous products, and products which would have required a separate package if shipped with the first shipment). Unless otherwise instructed, we will Ship and Backorder (if necessary) to ensure prompt delivery of all in-stock items.

Hold and Ship Complete

This shipping option instructs us to hold your entire order until all items are in stock. You authorize us to charge your credit card for the entire order amount to secure those parts for you in advance, even if the order cannot ship the same day due to backordered items. This will allow for all items on your order to ship at one time, but it can also cause indefinite delays in shipment if any items are not in stock and delivery from our suppliers is delayed. We do not recommend this option except for certain export orders or orders where the products not in stock are oversize or hazardous, which would require additional shipping charges if backordered and shipped later. If the only products missing are small and can be shipped by mail, we will backorder them and ship all in-stock items immediately. Please request this in the Special Instructions box in the Shopping Cart if you prefer this option.

Certificate of Conformance and Form 8130 (Export)

NAASCO provides you with its own Certificate of Conformance for our products at no charge. This is noted on every invoice. Factory certification and test reports are available on some items, and 8130 Forms are available on FAA-approved products. A cost of $15 per product on manufacturer certs and $50 per product on 8130 forms is charged to secure these forms. Please inquire at the time of order if test reports/8130 Forms are available for the items you are ordering. If available, the forms must be requested at the time of order, and in some cases, the product must be special ordered from the factory with the forms. These forms cannot be furnished after you receive the product. Anticipate shipping delays if 8130 Forms are requested. If you require these forms, you can request that the salesperson add them to your order. If you are ordering online, you can check off which form you require for each item in your cart. The system automatically adds the $15 or $50 charge to your bill. Due to delays and costs involved in furnishing these forms, we strongly suggest that you check to see if the NAASCO Certificate of Conformance will be acceptable instead of Form 8130.

Adding Onto an Order

In order to ensure efficient, accurate processing of orders in the warehouse, we have several restrictions for adding on to placed orders. The restrictions include:

  • Orders that have “Packed” or “Invoiced” status
  • Orders qualifying for free shipping
  • Orders containing special order items

We have also implemented a 1:00 pm local time cutoff for add-ons at the respective origin warehouse on the day the order is shipping. If the order has an “open” status and it is before the 1:00 pm cutoff, you can add on to it using the website or by calling our Customer Service department. If we cannot add products to the open order due to the above restrictions, we will gladly take a new order for the additional products.

When You Receive Your Order

Upon receipt, the package should be opened promptly, and the material should be checked against the packing slip enclosed. Any claims for lost or damaged merchandise must be made within 14 days of delivery. Items out-of-stock at the time of shipment will be marked as back-ordered to follow.’ These items will not be charged on the invoice enclosed with the package and will be forwarded as soon as delivery is received from our suppliers. The backordered items will not be charged until shipped. About 90% of the items featured in our catalog are carried in stock. Special items of hardware, bearings, unusual fittings, and slow-moving items are special ordered as required. However, even with the large inventory we carry, it is not uncommon to come up short on some items. If an item is missing and not marked backordered, please advise us immediately.


Although we make every effort to ship all orders complete, it is often necessary to backorder one or more items if we are out of stock. When the partial order is shipped and invoiced, you are not charged for the backordered item(s) until these items are shipped. You are billed only for what is shipped. A backorder is created and shipped as soon as the items arrive. The backorder is then invoiced, and any overpayment from the first invoice is applied to it. If you do not wish to have any items backordered, or wish to cancel an existing backorder, just let us know. We will do so immediately if the backorder has not been shipped. We are working continuously to keep all items in stock to preclude backorders. If a backorder is necessary, we do appreciate your patience. NAASCO pays the shipping costs within the 48 contiguous United States by surface shipping on backorders when the backordered items could have been shipped via UPS inside the first package at no additional freight cost. Except when the backordered items are oversize, hazardous, contain one gallon or larger, or COD shipments. We will continue to strive to maintain stock of all our products to keep the necessity for backordering parts to a minimum.

Special Order Items

Call or write and provide as much information as possible including make, model, serial number of aircraft and exact part number or product you need, plus your credit card number. Within 24 hours if possible, we will advise you of the price and delivery time on the item, at which time you can place your order if acceptable. Once an order is placed for a special order item, it cannot be canceled or returned and must be paid in advance. If we cannot drop ship your special order, then freight charges from the factory to our warehouse will be added to your invoice. 

Non-Stocking Items

Non-stocking products from NAASCO are products that we do not carry in our warehouses and must be specially ordered. It is the customer’s responsibility to determine that the product is correct for their own application. By purchasing non-stocking products, the customer agrees to pay any cancellation or restocking fee assessed by the manufacturer or supplier should the customer wish to cancel or return the item. Additional inbound freight may also apply to get non-stocking products from the manufacturer to our warehouse if a direct dropship is not an option. Some items may be non-cancellable / non-returnable once ordered. We suggest contacting a sales agent for lead time details prior to placing the order to ensure we can meet your delivery schedule. By submitting the order for a non-stocking product, you agree to these terms and conditions. Please call our sales staff for any additional questions or concerns.

Waiver Of Liability and Indemnification Agreement

Inasmuch as NAASCO has no opportunity to supervise the manufacture, installation, or maintenance of the parts supplied by it, nor any opportunity to participate in the design or manufacture of the various certificated and homebuilt aircraft in which its parts are utilized, the purchaser by placing an order and accepting said merchandise from NAASCO agrees that all materials purchased will be used solely at purchaser’s risk and that purchaser will indemnify and hold NAASCO, its owners and employees, free and harmless from all loss, liability or damage resulting from claims brought by any reason of any alleged failure or defect of any part or parts supplied by NAASCO.


If you choose to pick your order up in one of our locations, you must present your payment method at the time of pickup. If you paid by credit card, please bring your credit card with you to the store. If you are using a runner, we recommend applying for a net account. We do not accept personal checks at the Will Call store.

Method for Submitting Requests

You may submit a request by emailing [email protected] or by calling Sales at 1-631-399-2244.
