## The airworthiness directive

64-22-03 PIPER: Amdt. 802 Part 507 Federal Register August 28, 1964. Applies to Models PA-24 and PA-24-250 Aircraft Serial Numbers 24-1 through 24-3284.

Compliance required within the next 50 hours' time in service after the effective date of this AD, unless already accomplished.

To eliminate possible breakage or loosening of the wires leading to the landing gear safety switch with resultant malfunction of the landing gear safety switch accomplish the following:

  (a) On the left main landing gear, inspect for broken and loose wires and terminals at the connections to the landing gear safety switch. Repair any broken or loose wires and terminals before further flight.

  (b) Install Piper Kit No. 754475, or FAA approved equivalent, leaving sufficient slack in the wires between the new clamp and the safety switch to prevent pulling of the wires.

(Piper Service Letter No. 379, dated July 12, 1962, pertains to this subject.)

This directive effective September 28, 1964.
