ADs are legally binding safety orders issued under the Civil Aviation Regulations 1998. This fragment indicates the directive applies to all models of the De Havilland DHC-1 Chipmunk aircraft and concerns inspection or modification of the **flap return spring** and **flap check cable** systems. It references external technical documents (TNS DHC-1 Aust. No. 3 or 6) and demands compliance \"forthwith\" (immediately).
