Follow Maule Aerospace Technology, Inc. Mandatory Service Bulletin No. 30. This may be achieved by inserting a copy of this AD or inserting the text located on the bottom of page 3 of Maule Aerospace Technology, Inc. Mandatory Service Bulletin No. 30 into the FAA-approved maintenance program (e.g. maintenance manual).Note 1: CASA reminds operators that Civil Aviation Regulation (1988) 42G requires additional requirements to be complied with if any part of the flight control system of an Australian aircraft is assembled, adjusted, repaired, modified or replaced in the course of carrying out maintenance on the aircraft.Note 2: FAA AD 2008-24-02 Amdt 39-15742 dated 10 November 2008 refers.
Compliance:
Before the next time the elevator control cable is disconnected for any reason or within the next 12 calendar months after the effective date of this AD, whichever occurs first.
This Airworthiness Directive becomes effective on 12 February 2009.
Background:
This AD results from two reports of accidents where reversed elevator control rigging was a factor. The issuing of this AD is intended 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.
