Airworthiness Directives; Bombardier Model DHC-8-102, DHC-8-103, DHC-8-106, DHC-8-201, DHC-8-202, DHC-8-301, DHC-8-311, and DHC-8-315 Airplanes Equipped With a Cockpit Door Electronic Strike System Installed in Accordance With Supplemental Type Certificate (STC) ST02014NY

What this AD requires

This document publishes in the Federal Register an amendment adopting airworthiness directive (AD) 2008-26-03. This AD requires modifying the electronic strike system of the cockpit door. This AD results from a report indicating that the equipment is defective. We are issuing this AD to prevent failure of this equipment, which could compromise flight safety.

Applies only to airplanes equipped with a cockpit door electronic strike system installed in accordance with STC ST02014NY (equivalent to STC SA03-70).

Whether AD 2008-26-03 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 2008-26-03 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.
