Airworthiness Directive · Amendment 39-18875 · Fuselage
Dassault Aviation Airplanes
This AD applies to the Dassault Aviation airplanes specified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category, all manufacturer serial numbers.
(1) Model FAN JET FALCON and FAN JET FALCON SERIES C, D, E, F, and G airplanes.
(2) Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes.
We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model FAN JET FALCON airplanes; all Model FAN JET FALCON SERIES C, D, E, F, and G airplanes; and all Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. This AD was prompted by a determination that inspections for discrepancies of the fuselage bulkhead are necessary. This AD requires repetitive inspections for discrepancies of the fuselage bulkhead, and repair if necessary. We are issuing this AD to address the unsafe condition on these products.
Before exceeding 5,000 total flight cycles since first flight of the airplane, or within 500 flight cycles after the effective date of this AD, whichever occurs later: Do a detailed inspection for discrepancies of the fuselage bulkhead at FR 33 using a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA); or Dassault Aviation's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature. Repeat the inspection thereafter at intervals not to exceed 5,000 flight cycles.
If any discrepancy is found during any inspection required by paragraph (g) of this AD: Before further flight, repair using a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the EASA; or Dassault Aviation's EASA DOA. If approved by the DOA, the approval must include the DOA-authorized signature. Repair of an airplane as required by this paragraph does not constitute terminating action for the repetitive actions required by paragraph (g) of this AD, unless specified otherwise in the repair instructions.
