AD/PA-38/13 - Magnetic Compass Mounting Hardware - CANCELLED

This instrument cancels a previous safety rule that required owners of Piper PA-38 Tomahawk aircraft to replace the magnetic compass mounting hardware.

What it does:

• Removes a maintenance requirement: The original directive (issued in 1979) mandated that owners replace the compass mounting hardware within 100 hours of flight time, following specifications in a Piper Service Letter.
• Effective date: The cancellation took effect on 18 December 2008.

Who it affects:

• Owners and operators of Piper PA-38 Tomahawk series aeroplanes.
• Maintenance organisations that service these aircraft.

Why it matters: This removes an outdated regulatory burden. The Civil Aviation Safety Authority determined the compass hardware replacement was no longer necessary for safety, simplifying maintenance obligations for owners of these older aircraft.
