Does the flap gear box require servicing with oil or grease if so when and with what? I can’t find anything in the maintenance manual.

If the flap gear box you're referencing is the same thing as the flap linear actuator on my 750 STOL (Thomson "Electrak 050" linear motor #DE12-17W41), the manufacturer's spec sheet says it is maintenance-free and has an estimated life of a minimum 40,000 cycles.



Thanks John but it’s the older gearbox, motor and external limit switches
