Airworthiness Directives; Bombardier, Inc. Airplanes

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This AD was prompted by reports of inadvertent deployment of a single outboard spoiler during flight. This AD requires replacement of the power control units (PCUs) for the outboard spoilers with upgraded PCUs. We are issuing this AD to prevent leakage of the piston head seal and piston rod seals of the outboard spoiler PCUs, which could result in inadvertent spoiler deployment and reduced controllability of the airplane.

Which aircraft AD 2015-19-13 applies to

MakesBombardier, Inc.
ModelsDHC-8-400, DHC-8-401, DHC-8-402, DHC-8
Serial-conditional — narrows to serials 4001–4001, 4003–4453.
Part-conditional390700-1007.

Applies to airplanes with an outboard spoiler power control unit (PCU) having part number 390700-1007 installed in the outboard position.

Whether AD 2015-19-13 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:

Method of complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2015-19-13 complied with on your aircraft?

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.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
