Persons may include in their instructions an option to modify the ailerons to avoid the need for further inspections for corrosion and cracks (Requirements 1c and 1d).

            For Requirements 2 and 3: Before further flight after 7 September 2000.

            Note 5: The Requirement 3 inspection is not necessary if the joint has been modified to a design approved under CAR 35. See Note 4.

            This amendment becomes effective on 24 August 2000.

            Background:  The Civil Aviation Safety Authority received a report of the in-flight separation of the right hand aileron from a Skyfox CA25N aircraft. Investigation revealed that a failure occurred where the aileron's torque tube attaches to its spar.

            Further investigation has not been able to conclusively determine the cause of the failure. However it has revealed several potentially unsafe conditions that were not covered by the original issue of this AD. Therefore Amendment 1 expands the set of potentially unsafe conditions that must be checked before further flight. Also, in the absence of an active Type Certificate holder, Amendment 1 allows technically competent industry representatives to develop and approve their own safety solutions.

            The original issue of this Airworthiness Directive was effective from 7 July 2000.
