If the diameter of the cable mount attach hole is larger than\n\n.316 of an inch, replace the flap lever handle (refer to the illustrated parts catalogue for the part number), in accordance with the Instructions section of Piper SB 965.\n\n    b) Install a new bushing (using only Piper part number (P/N) 63900-174) into the cable mounting attach hole, in accordance with the Instructions section of Piper SB 965.\n\n    c) Replace the flap lever handle attach bolt with a new clevis bolt (Piper P/N 400 673 or standard P/N AN23-11) in accordance with the Instructions section of Piper SB 965.\n\n    d) Inspect the washer, nut, and cotter pin, and if damaged, replace washer (Piper P/N 407-564 or standard P/N AN960-10), nut (Piper P/N 404-392 or standard P/N AN320-3), and cotter pin (Piper P/N 424-051 or standard P/N MS24665- 132) in accordance with the Instructions section of Piper SB 965.\n\nNote 1: FAA AD 96-10-03 Amdt 39-9608 refers.\n\nNote 2: The Requirement instructions of this Directive do not mirror the instructions in Piper SB 965.

Failure of the flap handle attach bolt could cause a sudden retraction of the flaps, and result in loss of control.","sortOrder":0}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
