Plain English Summary

2/10 complexity

This mandatory Airworthiness Directive requires owners and operators of all DH 90 Dragonfly aeroplanes to take immediate action to prevent fuel spilling into trouser cowls or wing stubs during refuelling, which can ignite on hot exhaust stacks.

Compliance may be achieved by reworking inlet manifold drains to discharge away from exhausts, using physical covers/barriers during refuelling, or by following the older Air Navigation Order requirement — the change is required forthwith to eliminate fire risk.
