Airworthiness Directive 2014-24558
one-timeAirworthiness Directives; Honeywell International Inc. Air Data Pressure Transducers
What this AD requires
We are removing Airworthiness Directive (AD) 2012-26-15, which applied to certain Honeywell International Inc. air data pressure transducers as installed on various aircraft. AD 2012-26-15 required doing various tests or checks of equipment having certain air data pressure transducers, removing equipment if necessary, and reporting the results of the tests or checks. As an option to the tests or checks, AD 2012-26-15 allowed removal of affected equipment having certain air data pressure transducers. We issued AD 2012-26-15 to detect and correct inaccuracies of the pressure sensors, which could result in altitude, computed airspeed, true airspeed, and Mach computation errors. AD 2012-26-15 reported that 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. Since we issued AD 2012-26-15, we have received new data indicating that the safety risk is lower than originally estimated.
Which aircraft AD 2014-24558 applies to
Applies to air data pressure transducers as 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 (part/serial numbers not enumerated in source text). Installed on, but not limited to: Airbus A318-111/-112/-121/-122; A319-111/-112/-113/-114/-115/-131/-132/-133; A320-111/-211/-212/-214/-231/-232/-233; A321-111/-112/-131/-211/-212/-213/-231/-232; A330-223F/-243F/-201/-202/-203/-223/-243/-301/-302/-303/-321/-322/-323/-341/-342/-343; A340-211/-212/-213/-311/-312/-313/-541/-642 airplanes; AGUSTA S.p.A. AW139 helicopters; Bell 429 helicopters; Boeing 767-200/-300/-300F/-400ER and 777-200/-200LR/-300/-300ER/777F airplanes; Cessna 560XL (560 Excel and 560 XLS); Dassault MYSTERE-FALCON 900 and FALCON 2000; Embraer EMB-135BJ; Gulfstream GIV-X and GV-SP; Learjet 45; Pilatus PC-12/47E; and Viking (Twin Otter) DHC-6-400 airplanes
Whether AD 2014-24558 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:
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.
