The FAA adopts a new airworthiness directive (AD) for certain Maule Aerospace Technology, Inc. M-4, M-5, M-6, and M-7 series and Model M-8-235 airplanes. This AD requires 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 horn. This AD also requires you to insert a supplement into your maintenance program (maintenance manual). This AD results from two reports of accidents where reversed elevator control rigging was a factor. We are issuing 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.
To address this problem, you must do the following, unless already done:
| Actions | Compliance | Procedures |
|---|---|---|
| (1) Using yellow enamel paint, color code the following: (i) the top of the rear elevator control horn; (ii) the elevator control cable end attached to the top of the rear control horn; (iii) the bottom of the forward elevator control horn; and (iv) the elevator control cable end attached to the bottom of the forward control horn | Before the next time the elevator control cable is disconnected for any reason or within the next 12 calendar months after December 30, 2008 (the effective date of this AD), whichever occurs first. | Follow Maule Aerospace Technology, Inc. Mandatory Service Bulletin No. 30, dated March 4, 2008. |
| (2) Insert the following text into the rigging procedure section of your FAA-approved maintenance program (e.g. maintenance manual): “CAUTION—BEFORE FLIGHT WHENEVER ELEVATOR CABLES ARE RECONNECTED OR NEW CABLES INSTALLED: Always check operation of elevators after a cable reconnect by pulling back on the control and ascertain that the elevators are in the UP position.” | Before the next time the elevator control cable is disconnected for any reason or within the next 12 calendar months after December 30, 2008 (the effective date of this AD), whichever occurs first. | Follow Maule Aerospace Technology, Inc. Mandatory Service Bulletin No. 30, dated March 4, 2008. You may insert a copy of this AD or you may insert the text located on the bottom of page 3 of Maule Aerospace Technology, Inc. Mandatory Service Bulletin No. 30, dated March 4, 2008, into the FAA-approved maintenance program (e.g., 1 maintenance manual). |
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
