Plain English Summary

2/10 complexity

What this is: An Airworthiness Directive (a mandatory safety order issued by the aviation regulator) requiring owners of specific Cessna aircraft to inspect a critical mechanical part.

Who it affects: Owners and operators of Cessna 320 series aeroplanes with serial numbers from 320E0001 through to 320F0045.

What you must do: Carry out an inspection of the main landing gear down lock pin and set screw. These are mechanical components that lock the wheels in the 'down' position during flight and ensure the landing gear stays put when you’re on the ground.

When: You must complete this inspection within 100 hours of flying time (counted from when the engine is running) after 31 August 1976.

Why it matters: This directive addresses a specific safety defect to prevent the landing gear from collapsing or failing to lock properly during landing. The inspection follows technical guidance in Cessna Service Letter ME76-4.
