Unsafe Condition
Propeller blade failure due to scratch(es) within the first four outboard threads or other unairworthy conditions in the retention threads of McCauley Models 2A34C66/90AT-2, E2A34C73/90AT-8, and 2A36C23/84B-0 propellers.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Disassemble and inspect retention threads on blades and ferrules per Service Bulletin 151A. Replace blades with scratches in first four outboard threads or other unairworthy conditions. Repair blades with scratches from fifth thread inboard and repair/replate ferrules with sharp edges. Dye penetrant inspect threads if no scratches observed. Obtain special flight permit to operate to a base where AD is accomplished if needed.

If no scratch(es) or unairworthy conditions are observed, the blade retention threads must be dye penetrant inspected to confirm visual observations, before return to service. 4. Blades showing evidence of scratch(es) within the first four outboard threads or other unairworthy condition(s) must be replaced with an airworthy blade. Blades showing evidence of scratch(es) from the fifth thread and inboard, must be repaired before returning blade to service. Ferrules showing evidence of sharp edges on the threads must be repaired and replated in accordance with McCauley Service Bulletin 151A dated December 6, 1985, before returning to service. 5. A special flight permit may be issued in accordance with Federal Aviation Regulations 21.197 to operate the aircraft to a base where the AD can be accomplished.
