NAASCO has received FAA Approval to incorporate certain modifications for a great number of 150-amp and 160-amp starter generators, manufactured by APC and Lucas/Goodrich. This series of upgrades, dubbed our "Mercury Mod", substantially increases starter generator reliability while greatly reducing operator maintenance costs. Our patented modification includes the machining of new air passages in the units' drive-end and antidrive-end end bells.

Your modified unit also receives a new set of NAASCO's ETR™ FAA-PMA carbon brushes, a reconfigured fan cover and other proprietary elements. These elements, in addition to our advanced repair processes, serves a dual role to improve airflow past the carbon brushes and brush boxes, while at the same time, drastically improving the internal cooling of your starter generator as the trace amounts of carbon dust generated by our ETR carbon brushes is exhausted.

The overall parameters, characteristics and part numbers remain the same.

As with our ETR-20 improvements, all starter generators overhauled and upgraded with our "Mercury Mod™" programs are backed by an unprecedented, 1000-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.
