Amdt 1

Fuel Cock Control Lever - Modification 5/99

Applicability: DH 82, DH82A Tiger Moth and Queen Bee aircraft.

Requirement: Unless already previously accomplished, modify the fuel cock control (rear cockpit) to ensure positive locking in the “ON” position and to allow rapid movement of the lever to the “OFF” position in the event of an emergency. The recently issued British Aerospace Modification Moth 155 meets the requirement of this Directive.

Compliance: Within 25 hours of the effective date of this directive. This Amendment becomes effective on 20 May 1999.

Background: During investigation of a recent accident involving a Tiger Moth in UK, the investigating authority recommended that provision be made for positive locking of the fuel cock lever. AD/DH82/2 was issued in 1984 to achieve this, however the requirement documents quoted at the time are now out of date. This amendment is to incorporate the recently issued BAe Modification on the matter.

The original issue of this Airworthiness Directive became effective on 28 November 1958.
