Plain English Summary

2/10 complexity

This Airworthiness Directive requires owners/operators of DHA-3 (Drover) aeroplanes not modified by "DH Mod. DRO 92, Issue 2" to perform recurring inspections of the horizontal tailplane rear spar every 100 flight hours to detect cracks, using an approved penetrant or 10× magnification. Any crack found must be repaired to the Secretary’s satisfaction (or under ANO 105.1.14.14.6.6) before flight. It prevents catastrophic structural failure and loss of control.
