What this AD requires

We are revising airworthiness directive (AD) 2018-01-12 for Airbus Helicopters Model AS350B3 helicopters to correct an error. As published, AD 2018-01-12 referenced an incorrect monostable toggle switch part number (P/N) in the preamble and regulatory text. This document corrects the error. In all other respects, the original document remains the same.

Which aircraft AD 2018-01-12 applies to

Applicability depends on the aircraft’s type certificate — check it against the specific tail.

Whether AD 2018-01-12 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 2018-01-12 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.
