REGULATORY TEXT:  
74-13-03 PIPER: Amendment 39-1872 as amended by Amendment 39-2588. Applies to Models PA-23-235 and PA-23-250 aircraft Serial Nos. 27-1 through 27-4654, Models PA-24, PA-24-250 and PA-24-260 aircraft Serials Nos. 24-1 through 24-5047, Model PA-24-400 aircraft Serial Nos. 26-2 through 26-148, Model PA-30 aircraft Serial Nos. 30-1 through 30-2000 Model PA-39, Serial Numbers 39-1 through 39-155 certificated in all categories. Compliance required as indicated unless previously accomplished. To prevent possible hazards in flight associated with the corrosion of the stabilator attachment bolts, accomplish the following:

1. Within the next 100 hours in service, unless previously accomplished, and at intervals not to exceed three years or five hundred hours in service from the last inspection, whichever occurs first, remove the four (4) stabilator attachment bolts and inspect for corrosion.

2. If corrosion is found, before further flight, replace the bolt, nut and washer with unused parts of the same part numbers or equivalent. The bolt can be replaced with an equivalent corrosion resistant AN bolt.

3. If a corrosion-resistant AN bolt or equivalent is used, compliance with the requirements of the AD may be discontinued.

4. Equivalent parts must be FAA approved.

5. Upon submission of substantiating data by an owner or operator through an FAA Maintenance Inspector, the Chief, Engineering and Manufacturing Branch, FAA, Eastern Region, may adjust the repetitive inspection interval specified in this AD.

(Piper Service Letters No. 667A and 772 refer to this subject).

This amendment 39-2588 is effective April 30, 1976.
