Summary
We propose to adopt a new airworthiness directive (AD) for certain Maule Aerospace Technology, Inc. Models M-4, M-5, M-6, M-7, and M-8 series airplanes. This proposed AD would require you to paint the top of the rear elevator control horn, the elevator control cable end attached to the top of the rear control horn, the bottom of the forward elevator control horn, and the elevator control cable end attached to the bottom of the forward control. This proposed AD would also require you to insert a supplement into your maintenance program (maintenance manual). This proposed AD results from two reports of accidents where reversed elevator control rigging was a factor. We are proposing this AD to reduce the likelihood of a mechanic rigging the elevator controls backwards, which could result in elevator movement in the opposite direction from control input. This condition could lead to loss of control.
