Airworthiness Directives; Bombardier Model DHC-7 and DHC-8 Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to certain Bombardier Model DHC-7 and DHC-8 series airplanes, that requires a one-time visual inspection to determine the serial number of the brake shuttle valves of the main landing gear (MLG); and replacement of the filter fittings with new filter fittings, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to ensure that proper filter fittings are installed. Installation of improper filter fittings could result in failure of the brake shuttle valves, and consequent loss of brake effectiveness, which could reduce controllability of the airplane during taxi, takeoff, and landing roll.

Whether AD 98-32622 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 compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 98-32622 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.
