Is AD 2012-26-15 a recurring Airworthiness Directive?

No — AD 2012-26-15 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2012-26-15 apply to?

AD 2012-26-15 applies to Honeywell. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Honeywell International Inc. Air Data Pressure Transducers

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Honeywell International Inc. air data pressure transducers as installed on various aircraft. This AD requires various tests or checks of equipment having certain air data pressure transducers, and removal of equipment if necessary. As an option to the tests or checks, this AD allows removal of affected equipment having certain air data pressure transducers. This AD was prompted by a report of a pressure measurement error in the pressure transducer used in various air data systems, which translates into air data parameter errors. We are issuing this AD to detect and correct inaccuracies of the pressure sensors, which could result in altitude, computed airspeed, true airspeed, and Mach computation errors. These errors could reduce the ability of the flightcrew to maintain the safe flight of the aircraft and could result in consequent loss of control of the aircraft.

Which aircraft AD 2012-26-15 applies to

MakesHoneywell

Applies to air data pressure transducers installed in air data computers (ADC), air data modules (ADM), air data attitude heading reference systems (ADAHRS), and digital air data computers (DADC) having the part numbers and serial numbers identified in Honeywell Alert Service Bulletin ADM/ADC/ADAHRS-34-A01, dated November 6, 2012. Installed on, but not limited to: Airbus A318/A319/A320/A321/A330/A340 series; Agusta AW139; Bell 429; Boeing 767-200/-300/-300F/-400ER and 777-200/-200LR/-300/-300ER/777F; Cessna 560XL; Dassault Mystere-Falcon 900 and Falcon 2000; Embraer EMB-135BJ; Gulfstream GIV-X and GV-SP; Learjet 45; Pilatus PC-12/47E; and Viking (Bombardier/de Havilland) DHC-6-400.

Whether AD 2012-26-15 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.

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.
