Airworthiness Directives; Dassault Aviation Airplanes

What this AD requires

The FAA is removing Airworthiness Directive (AD) 2010-26-05, which applied to certain Dassault Aviation Model Falcon 10 airplanes; Model FAN JET FALCON, FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes; and all Model MYSTERE-FALCON 200 airplanes; Model FALCON 2000 and FALCON 2000EX airplanes; Model MYSTERE-FALCON 50 and MYSTERE- FALCON 900 airplanes; and Model FALCON 900EX airplanes. AD 2010-26-05 required repetitive inspections for overpressure tightness on the pressurization control regulating valves and, if necessary, replacing the affected valve with a serviceable unit. The FAA issued AD 2010-26- 05 to address failure of the pressurization control regulating valve (overpressure capsule), which will affect the aircraft's overpressure protection. Since the FAA issued AD 2010-26-05, the FAA issued ADs 2021-04-20, 2020-02-13, 2020-03-24, 2020-03-19, 2020-01-13, 2023-05-15, 2023-04-10, 2023-02-13, 2023-04-18, and 2023-04-13 to address the unsafe condition. Therefore, the FAA has determined that AD 2010-26-05 is no longer necessary. Accordingly, AD 2010-26-05 is removed.

Repetitive inspection. Re-inspect. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Certificated in any category. Group 1 (Falcon 10; FAN JET FALCON series C/D/E/F/G; MYSTERE-FALCON 20-C5/D5/E5/F5), all serial numbers, applies only when equipped with Liebherr or ABG-Semca pressurization outflow valves. Group 2 (MYSTERE-FALCON 200; MYSTERE-FALCON 50; MYSTERE-FALCON 900; FALCON 900EX; FALCON 2000; FALCON 2000EX) applies to all serial numbers with no valve restriction.

Whether AD 2023-26662 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 2023-26662 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.
