Plain English Summary

2/10 complexity

This Airworthiness Directive (AD) mandates a safety modification for specific Piper Cherokee and Arrow aircraft models.

Which aircraft? Four specific models of Piper PA-28 series planes (PA-28-180, PA-28R-180, PA-28R-200, and PA-28-235) with particular serial numbers, but only if they have a "rocker type" pitch trim switch mounted on the pilot's control wheel (control yoke).

What action is required? Owners or operators must modify the pitch trim switch according to the instructions in Piper Service Bulletin No. 332. This bulletin (essentially a manufacturer-issued repair notice) contains the technical specifications for the fix.

Deadline? The work must be completed within 200 hours of flight time after 30 July 1971.

Why is this important? The pitch trim system adjusts the aircraft's nose-up or nose-down attitude. A faulty rocker switch could potentially cause sudden or unintended pitch changes, creating a safety risk during flight. This directive ensures the switch meets safer design standards.
