Applicability: All DHC-1 aircraft.

Requirement: Action in accordance with British Aerospace Technical News Sheet CT (C1) No.176 Issue 2.

Note: UK CAA AD 014-11-97 refers.

Compliance: As specified in the Requirement document.

This Amendment becomes effective on 25 December 2003.

Background: The tailplane attachment fittings are lifed items, but in most cases the history of the installed fittings was not known. This Directive required an inspection within 3 months, then replacement of all fittings with C1.TP.313 fittings within 15 months.

Amendment 2 is issued to update the Requirement document to the current issue.
