60-03-07 PIPER: Amdt. 88 Part 507 Federal Register January 26, 1960. Applies to PA- 23 Aircraft Serial Numbers 23-747 To 23-1534 Inclusive. Compliance required not later than March 1, 1960. To preclude recurrence of short circuiting of the control circuits of the engine starter solenoids, electric cables Nos. P2B, P20A and P20B in the starter solenoid circuits shall be increased in size to 16 gage and a 15 ampere trip-free circuit breaker installed in the circuit at the point where lead P2B connects into the electric system. An appropriate placard must be installed adjacent to the new circuit breaker to provide adequate identification. (Piper Service Bulletin No. 175 dated June 9, 1959, covers this subject.)
