COMPLIANCE:

INTRODUCTION: There have been reports in the field of the trim filler plate mounting (stacked with the trim fitting

and trim hinge) positioned incorrectly on the M20J, M20R and M20TN Mooney Airplanes. We

are issuing this Service Bulletin because we evaluated all the relevant information and determined the unsafe condition described in SB M20-313 (initial release) is likely to exist in other products of the same type design. This will require an inspection and corrective action

taken. The attached compliance card needs to be filled out and returned to Mooney

Aviation Company upon completion of this Service Bulletin M20--313A.
