Plain English Summary

3/10 complexity

This AD requires operators of the listed DHC‑8 models to revise their Transport Canada–approved maintenance programs to add the AWL Structural Inspection Task 5310/31A, using the specified Temporary Revisions for each model. It sets mandatory inspection timings tied to an aircraft's flight-cycle count and phases in inspections for items designated PSEs (see Compliance a–c). The rule obliges operators and maintenance organisations to perform and record those inspections by the effective date (18 May 2000).

Applicability: DHC-8 aircraft, Models 102, 103, 106, 201, 202, 301, 311, 314, and 315.

Requirement: Revise the Transport Canada approved maintenance program by incorporating the inspection and the inspection intervals of Airworthiness Limitations List (AWL), Structural Inspection Task 5310/31A as detailed in the Temporary Revisions (TRs) of the DHC-8 Maintenance Program Manuals specified below:

DHC-8 Models	Maintenance Program Manual	Temporary Revision No.
102, 103, 106	PSM 1-8-7	TR AWL-71
201, 202	PSM 1-82-7	TR AWL2-15
301,311, 314, 315	PSM 1-83-7	TR AWL3-78

For those angles designated as PSEs, phase in the structural inspection tasks detailed above in accordance with the compliance part of this Directive.

Compliance: a. For aircraft that have accumulated less than 8,000 flight cycles as of 18 May 2000, perform the inspection at 10,000 flight cycles.

b. For aircraft that have accumulated more than 8,000 flight cycles as of 18 May 2000, perform the inspection within 2,000 flight cycles after 18 May 2000.

c. For aircraft that have accomplished the 40,000 flight cycle inspection, and where no cracks were found and/or where the closing angles were replaced, the repeat interval of 10,000 flight cycles starts from the date of the 40,000-flight cycle inspection and/or the date of replacement of the closing angles.

This Airworthiness Directive becomes effective on 18 May 2000.
