63-27-03 PIPER: Amdt. 661 Part 507 Federal Register December 24, 1963. Applies to All Models PA-24 and PA-24-250 Aircraft, Which Have 25 Ampere Circuit Breakers in the Landing Gear Retraction Motor Circuit.
Compliance required within the next 100 hours' time in service after the effective date of this AD.
Inadvertent tripping of the 25 ampere landing gear retraction circuit breaker has resulted in stoppage of the landing gear retraction mechanism in other than the fully extended position. Therefore, in order to eliminate this condition, with its associated hazard of partial-gear-down landing accidents, the 25 ampere circuit breaker in the landing gear retraction motor circuit must be replaced with a 30 ampere circuit breaker, Piper P/N 454661, or FAA approved equivalent.
(Piper Service Letter No. 356, dated March 31, 1961, pertains to this same subject.)
This directive effective January 23, 1964.
