Plain English Summary

1/10 complexity

This Airworthiness Directive (AD) mandates a safety inspection for specific light aircraft. It requires owners or operators of Call Air A-9 series aeroplanes to check the main landing gear attachment points for cracks.

Specifically, you must inspect the welded areas of wing-to-fuselage struts with part numbers 10915-1 and 10915-2. These inspections must happen every 100 hours of flight time (calculated as "time in service") starting from 1 September 1971.

The purpose is to detect fatigue cracking in the welded joints before they lead to landing gear failure, which could cause an accident during takeoff or landing.
