What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-145 and EMB-135 series airplanes, that requires replacement of the engine-driven hydraulic pump. This action is necessary to prevent engine oil leakage at the coupling seal between the hydraulic pump and the engine gearbox from causing low engine oil levels, which could lead to in-flight engine shutdown and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.

Whether AD 05-13142 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 05-13142 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.
