Plain English Summary

2/10 complexity

This directive mandates that owners/operators of CASA C‑212 aircraft have flap control rod joints inspected and modified exactly as specified in CASA Service Bulletin 212‑27‑22 Rev. 3, to be completed prior to 30 September 1989. It responds to overseas reports (and an FAA AD) of bolts separating from flap linkages—risking flap‑control failure and asymmetric retraction—and shifts the cost and execution responsibility to operators.

AD/CASA/12 Flap Control Rod Joints 7/89 DM

Applicability: All model C-212.

Requirement: Action in accordance with CASA Service Bulletin 212-27-22 Rev. 3. Compliance: Prior to 30 September 1989.

Background: Reports have been received overseas that failed bolts, lacking positive retention, may separate from the flap linkage. This could lead to flap control system failure and asymmetric flap condition on retraction. The F.A.A. have issued an A.D. 89-05-01 on the subject.
