Compliance required as indicated:

(a) Within the next 50 hours in service after the effective date of this AD, unless already accomplished
within the last 50 hours in service, and thereafter at intervals not to exceed 100 hours in service from the last inspection, visually inspect for cracks each of the castings listed herein. When any casting is replaced by the respective forging listed herein, the repetitive inspections of this paragraph and paragraph (b) are no longer required for that forging.

(b) For airplanes having 1,000 or more hours in service, remove the subject castings from the aircraft, clean thoroughly removing all paint, and perform a dye penetrant inspection for cracks, within the next 100 hours in service after the effective date of this AD, unless already accomplished within the last 400 hours in service, and thereafter at intervals not to exceed 500 hours in service from the last inspection. Prior to reinstallation of castings without cracks, clean thoroughly, and apply zinc chromate primer.

(c) Replace cracked castings before further flight with a replacement forged or cast part.

(d) Inspection and reassembly shall be accomplished in accordance with Piper Service Bulletin No. 155B, dated October 28, 1963, or FAA-approved equivalent.

NOTE: For paragraph (a), it is necessary to remove the tail cone, covers, and fairings to gain access to most of the parts to be inspected. However, parts need not be disassembled and/or removed from the aircraft to accomplish this inspection. All of the forged parts listed herein have integral raised digit forging numbers. Therefore, the absence of raised digits will serve to identify the part as a casting.
