Airworthiness Directives; Zodiac Aero Evacuation Systems (Also Known as Air Cruisers Company) Airplanes

What this AD requires

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to Zodiac Aero Evacuation Systems (also known as Air Cruisers Company) fusible plugs installed on emergency evacuation equipment for various transport category airplanes. As published, the email address for requesting service information specified in the preamble and regulatory text is incorrect. This document corrects that error. In all other respects, the original document remains the same.

Which aircraft AD 2018-23-12 applies to

MakesAir Cruisers Company

Applies to Zodiac Aero Evacuation Systems (also known as Air Cruisers Company) fusible plugs installed on emergency evacuation equipment identified in 16 specific Air Cruisers service bulletins (covering 737, 757, 767, 777, A300/A310, A310, A320, A321, BAe 146, F28, F100, a generic Liferaft SB, and MD11/MD80/90/717 evacuation equipment). Affected plugs may be installed on evacuation equipment on airplanes made by Airbus SAS, The Boeing Company, BAE Systems (Operations) Limited, and Fokker Services B.V.; applicability is determined by installation of the identified equipment, not by airframe model/serial number.

Whether AD 2018-23-12 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 2018-23-12 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.
