Cessna 177 - Stabilator Balance Weight Arm Bracket
Cessna have advised in SESB 89-1 dated 3 February 1989 of possible cracking of the stabilator balance weight arm bracket. This Authority was concerned about Cessna's compliance requirement because they only designated it as "recommended" and they were contacted for clarification.
Cessna have replied that the reported cracks were small and only over a limited number of aircraft owned by one operator. We agreed that an AD should not be raised at this time. However, owing to the critical nature of balance weights and their security, this Authority strongly advises all owners/operators of the aircraft to ensure that the inspections specified in the S.B. are carried out. It must be understood that failure of a balance weight arm could well result in loss of the aircraft. Any brackets with any cracking warrant an immediate Major Defect Report.
