Plain English Summary

1/10 complexity

This is a mandatory safety rule (called an Airworthiness Directive) for owners and operators of Piper PA-22 Tri-Pacer and Colt aeroplanes.

What it requires: Every 100 hours of flight time, you must inspect a specific part called the tailplane actuating jack (part number 4296-02). This device helps control the aircraft's horizontal tail.

Specifically, check:

The nut and washer at the top end for excessive wear
That the part is properly lubricated
That the jack-shaft has only minimal 'end play' (looseness) — just enough to let it rotate freely through its full range of motion

Why it matters: This ensures the tail control mechanism operates safely and doesn't fail in flight due to wear or lack of lubrication.

Applicability: All models.

Requirement: Inspect the nut and washer at the upper end of the tailplane actuating jack (P/N 4296- 02) for excessive wear and adequate lubrication. End play in the jack-shaft should only be sufficient to permit free rotation of the shaft throughout the operating range.

Compliance: At intervals not exceeding 100 hours time in service.
