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 failure could lead to loss of control. Compliance (e) 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. maintenance manual).
