Plain English Summary

2/10 complexity

This Airworthiness Directive (AD) mandates a safety fix for specific Piper Apache and Aztec aircraft.

What it requires: Owners and operators of certain Piper PA-23 and PA-23-160 model aircraft (serial numbers 23-1 through 23-1691) must modify the elevator control tube bellcrank attachment — a component that connects the pilot's control inputs to the elevator (the part of the tail that makes the plane pitch up and down).

Compliance: After 30 May 1960, this modification must be inspected or checked at intervals not exceeding 100 hours of flight time ("time in service") to ensure it remains airworthy.

Why it matters: This addresses a potential mechanical defect in the control system that could affect the pilot's ability to control the aircraft's pitch, posing a safety risk if not corrected and regularly monitored.
