Applies to PA-31 and PA-31-325 and PA-31-300 aircraft, S/N 31-2 through 31-7512029, and PA-31-350 aircraft, S/N 31-5001 through 31-7552052 certificated in all categories, except airplanes modified to incorporate all three kits denoted in Piper Aircraft Corporation Service Letter 739, dated June 2, 1975.
Compliance required within the next 50 hours in service after the effective date of this AD, unless already accomplished.

Upon request, with substantiating data, submitted through an FAA maintenance inspector, the compliance time specified in this AD may be increased by the Chief, Engineering and Manufacturing Branch, FAA Eastern Region.
