AIRWORTHINESS DIRECTIVE

Number: G-2014-0001-E

Issue date: 21 March 2014

This Airworthiness Directive (AD) is issued by the UK CAA as the National Aviation Authority 

(ICAO Annex 8 Authority of State of Design) for the affected product(s).

In accordance with Articles 19 (1) and 22(1) of The Air Navigation Order 2009, the following 

action required by this AD is mandatory for applicable aircraft registered in the United 

Kingdom. No person may operate an aircraft to which an AD applies except in accordance 

with the requirements of that AD unless otherwise agreed with the Authority of the State of 

Registry.

Type Approval Holder’s Name:

de Havilland Support Ltd 

Type/Model Designation(s):

DH82

TCDS: n/a – AAN 22556 Issue 9 (or later) refers

Supersedure: Not Applicable

ATA 55 Fuselage Main Structures – Lower Fuselage Tie-Rods

Manufacturer(s): de Havilland, Morris Motors and others

Applicability: All DH82 Tiger Moth, DH82A Tiger Moth and DH82B Queen Bee 

aeroplanes, all variants and replicas excluding Thruxton Jackaroo 

(DH82A Modified) 

Reason: Preliminary examination of an aircraft which crashed in Australia 

indicated that both of the aircraft’s fuselage lateral tie rods, which join 

the lower wings to the fuselage, had fractured in the threaded section 

near the join with the left wing (at areas of significant pre-existing fatigue 

cracking). The failed tie rods, part number JRA-776-1, were 

manufactured under an Australian Parts Manufacturing Approval.

Some aircraft on the UK Register and other fleets may have embodied 

such PMA parts as alternative means of compliance, and this AD is to 

cover the intent of CASA Australia PAD/DH 82/17 removing any 

unacceptable tie-rods and nuts from service.
