Servo tab

RT · Post by RT » Wed Jan 04, 2017 7:15 am

I have an M4-180c project that has had the rudder servo tab area covered over. There is no documentation of this modification. It seems like it would be a lot easier to leave it as is than try to put one on.
Has anyone got documentation for doing this? A 337 field approval or a letter from Maule or whatever it takes to make it legal.

I have heard that a few planes (maybe 5) have left the factory like that, so maybe it is on the T.C.? Or perhaps i am wrong....

There were about 10 M4 180V's made for the trainer market that also did not have the cargo door.

That didn't take as long as I thought it would. The rudder tab is required on all M-4's according to our TC. It would have to be done under a 337 or field approval.

Pilot, The 5 aircraft you reference without the servo tab were the first 5 M7 in 1984 which had instead a bungee direct rudder/aileron interconnect.

Has anyone done a 337 and could help with paperwork?
