Airworthiness Directive 2015-05-07

What this AD requires
We are superseding Airworthiness Directive (AD) 2015-02-06 for certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. AD 2015-02-06 required a revision to the airplane flight manual, a revision to the maintenance or inspection program, as applicable, and replacement of horizontal stabilizer trim actuators (HSTAs) having certain part numbers. This new AD continues to require those actions and corrects certain typographical errors. This AD was prompted by the discovery of three typographical errors in AD 2015-02-06. We are issuing this AD to detect and correct loose spur gear bolts on the HSTA, which, if combined with the failure of the primary load path, could lead to failure of the HSTA and subsequent loss of the airplane.
Which aircraft AD 2015-05-07 applies to
CL-604 Variant of the CL-600-2B16; applies only when equipped with horizontal stabilizer trim actuator (HSTA) P/N 604-92305-3 (vendor P/N 8454-1) or P/N 604-92305-5 (vendor P/N 8454-2).
Whether AD 2015-05-07 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
