Plain English Summary

2/10 complexity

This is a safety directive for owners and operators of Piper PA-20 (Pacer) series aeroplanes. It mandates a specific inspection of the upper cabin structure to detect corrosion before it compromises airworthiness.

What you must do:

Remove interior trim to expose structural components at the top of the windshield, the front and rear spar carry-through (the structure that continues the wing spars through the cabin), and the upper longerons (the main longitudinal support beams running along the cabin roof).
Visually inspect these exposed metal parts for corrosion (rust) and check whether the protective coatings are still intact.

When to comply:

Initial inspection: Must be completed before 1 January 1979, unless the aircraft was already inspected after 1 July 1977.
Recurring inspections: Every 3 years thereafter.

This ensures the aircraft's frame remains structurally sound and safe to fly.
