Plain English Summary

2/10 complexity

What this requires: Owners and operators of De Havilland DH 104 (Dove) aircraft must inspect specific control surface components—the hinge links and brackets for the ailerons, rudder, and elevator, plus the upper attachment fittings for the tailplane.

Who must comply: Anyone operating a DH 104 Dove that has not been modified according to Modification Numbers 841, 842, or 843.

When to do it: Every 200 hours of flight time (called "time in service"), starting from 1 September 1971.

Why it matters: These inspections prevent structural failures in critical flight control surfaces and the tailplane attachment points, which could lead to loss of aircraft control.

Technical references: The inspections must follow procedures set out in either:

De Havilland Technical Note TNS CT(104) No. 123 Issue 4, or
Airworthiness Notice ANO 105.1.1.4.13.6.8.
