Airworthiness Directives; Bombardier-Rotax GmbH Type 912 F, 912 S and 914 F Series Reciprocating Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to Bombardier-Rotax GmbH Type 912 F, 912 S and 914 F series reciprocating engines. This action requires venting of the lubrication system and inspection of the valve train on all engines. This action also requires venting of the lubrication system of all engines on which the lubrication system has been opened, and any engine on which the propeller has been rotated one full turn in the reverse direction. This amendment is prompted by reports of several in-flight engine failures, all of which resulted in forced landings. The actions specified in this AD are intended to prevent damage to the engine valve train due to inadequate venting of the lubrication system which can result in an in-flight engine failure and forced landing.

Whether AD 02-26912 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 02-26912 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.
