The airworthiness directive
55-03-01 CONVAIR: Applies to All Model 340 Aircraft.
Compliance required as indicated.
A 340 was involved in a flight accident due to the AN 310-4 nut coming off of the AN 174-33 bolt that attaches the left-hand elevator servo tab idler to the structure resulting in flutter of the elevator servo tab, with subsequent failures at the elevator control system and loss of elevator control. As a precautionary measure, the following is required: As soon as practical but not later then the next 15 hours service, inspect the control systems for the servo tab on the left elevator and on the right elevator trim tab on all 340 aircraft. Inspection is to cover all nuts, bolts, idlers, bellcranks, pushrods and general security check of all nuts and bolts.
