REGULATORY TEXT:  
88-21-07 R1 PIPER: Amendment 39-6042 as revised by Amendment 39-6272.

Applicability: Model PA-23, PA-23-160, PA-23-250, PA-23-235 and PA-E23-250 (all serial numbers) airplanes certificated in any category, except Model PA-23-250 airplanes, serial numbers 27-7654001 through 27-8154030.

Compliance: Required within the next 60 calendar days after the effective date of this AD and at intervals not to exceed 12 calendar months thereafter, unless already accomplished per the unrevised version of this AD.

To reduce the possibility of precipitation and/or wash water from entering the fuel filler compartment and leaking into the fuel cell resulting in engine failure, accomplish the following:

(a) Inspect the fuel vent/drain lines, the thermos type fuel cell caps, and the fuel filler compartment covers on both main fuel cell systems and, if installed, both auxiliary fuel cell systems in accordance with the instructions in Piper Service Bulletin (SB) No. 340, dated May 24, 1971.

(b) If any defects are found, correct them before further flight.

(c) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished.

(d) An equivalent means of compliance with this AD may be used if approved by the Manager, Atlanta Aircraft Certification Office, ACE-115A, Federal Aviation Administration, 1669 Phoenix Parkway, Suite 210C, Atlanta, Georgia 30349.

This AD revises AD 88-21-07, Amendment 39-6042, which became effective on November 6, 1988.

This amendment (39-6272, AD 88-21-07 R1) becomes effective on August 22, 1989.
