Plain English Summary

1/10 complexity

What this rule does

This is a safety inspection requirement for owners of specific light aircraft. It mandates regular visual checks of the engine mount structure to detect dangerous cracks before they cause failure.

Who it affects

Owners and operators of:

Cessna 180 series aircraft
Cessna 182 series aircraft
Wren 460 series aircraft

(Note: This does not apply to Cessna R182 models, which have a different engine mount design.)

What you must do

You must visually inspect the engine mount (the metal framework that attaches the engine to the aircraft body) for cracks. Pay particular attention to the welded joints (where metal pieces are fused together) connecting the rear cross member to the bearer tubes (the support pipes).

When to comply

Perform this inspection at least once every 100 hours of flight time (called "time in service").
