What is a Mercury Mod? NAASCO has received FAA approval to incorporate certain modifications for a variety of 150-amp, 160-amp, 200-amp and 400-amp starter generators manufactured by Skurka (formerly APC) and Lucas/Goodrich. This series of upgrades, dubbed our “Mercury Mod™” and “Mercury Mod Phase II™ upgrades.

In addition to receiving our exclusive ETR™ FAA-PMA carbon brushes, your modified starter generator is fitted with a variety of proprietary elements. In many instances, modifications include machining new air passages in the units’ drive-end and antidrive-end end bells. These elements, in addition to our advanced repair processes, serves a dual role to improve airflow past the carbon brushes and brush boxes while drastically improving the internal cooling of your starter generator. Trace amounts of carbon dust generated by our ETR carbon brushes is exhausted to complete the cooling function. Our unparalleled upgrades substantially increase starter generator reliability and greatly reduce operator maintenance costs and  overhead.

The overall parameters, characteristics and part numbers remain the same. As with our ETR-20™ improvements, all starter generators overhauled and upgraded with our MOD programs are backed by NAASCO’s 1,000-hour, “No Brush Change” warranty. Overhauls are performed in accordance with OEM component maintenance manuals as well as NAASCO’s strict ETR-20™ and ETR-25™ guidelines. Each of our FAA and EASA approved, flight-tested and trend monitored programs ensure that your starter generator is cleaned, lubricated and tested using the latest state-of-the-art materials and processes.
