Airworthiness Directives; Viking Air Limited Model DHC-3 (Otter) Airplanes With Supplemental Type Certificate (STC) SA 09866SC

What this AD requires

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to Viking Air Limited Model DHC-3 (Otter) airplanes equipped with a Honeywell TPE331- 10 or -12JR turboprop engine installed per STC SA09866SC (Texas Turbines Conversions, Inc.). The wording on how the AD is justified and the wording of the temporary placard need clarification. The clarification does not affect the actions of the AD. This document makes this clarification. In all other respects, the original document remains the same.

Whether AD 2011-26002 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 2011-26002 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.
