Plain English Summary

1/10 complexity

This Airworthiness Directive (AD) requires owners and operators of specific Twin Commander aircraft to inspect the elevator bungee springs — components that help centre and provide feel to the elevator (tailplane) controls — to ensure they are in safe working condition.

Who it affects:

Owners of Rockwell Commander twin-engine aeroplanes with serial numbers 1 to 1876
Owners of model 500S aeroplanes with serial numbers 3050 to 3099
Owners of model 681 aeroplanes with serial numbers 6001 to 6060

What you must do: Complete an inspection of the elevator bungee springs within 100 hours of flight time after 30 September 1978, following the procedures set out in Rockwell International Service Letter No. 225A.

Why it matters: The directive addresses potential failures in these springs that could impair elevator control, posing a safety risk during flight. Compliance ensures the aircraft remains airworthy and safe to operate.
