Plain English Summary

3/10 complexity

This directive requires operators of specified Bombardier/De Havilland DHC‑8 aeroplanes (certain airframe and nose‑gear drag‑strut serial numbers) to carry out the inspections, repairs or replacements set out in Transport Canada AD CF‑95‑15, or install De Havilland Modification 8/2266 (which terminates the inspections). It responds to pivot‑tube cracking that has led to nose‑gear failures; CASA enforces the AD and affected operators bear the compliance costs and downtime.

Note: Incorporation of de Havilland Modification 8/2266 provides terminating action for the inspection requirements of this Directive.

In one case the nose gear did not extend, causing damage to the aircraft during the subsequent landing. As a result of these failures, the safe life of the pivot tube has been re-evaluated.
