and how to look for any cracking. The pilot should also be aware of the possible consequences of partial or total separation of the elevator trim tab.

 Compliance: Before the first flight of every day.

            If operations of the aircraft are such that more than 5 hours are flown during the day, the inspection is to be carried out every 5 hours flight time until the end of flying for that day.

            This Amendment becomes effective on 15 June 2000.

 Background: On return from a flight a trim tab was found nearly departed from an aircraft.
            Investigations found that the cause was bond failure between the hinges and the attaching resin. A further 6 tabs have since been found debonded, with one of the tabs having little more than 50 hrs TTIS. A loose trim tab can lead to flutter of the control surface. The manufacturer has been advised, and the initial issue of this AD was an interim solution pending development of a permanent solution.

            Service experience with tabs which have been repaired/modified in accordance with the above scheme shows that it is effective in preventing this type of failure. This amendment excepts modified tabs from the requirement.

            The initial issue of this Airworthiness Directive became effective on 6 May 1998.
