Airworthiness Directive · Amendment 39-18932 · Fuselage
Dassault Aviation Airplanes
This AD applies to Dassault Aviation Model FALCON 7X airplanes, certificated in any category, serial numbers (S/Ns) 2, 5, and 8 through 182 inclusive; except S/Ns 141, 148, 149, 157, 159, 166, 170, 171, 174, 175, and 177 through 180 inclusive.
We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by reports that during the assembly of structural elements on some airplanes, lack of established procedures and tools caused boring and torqueing defects to be present at some locations. This AD requires a detailed visual inspection of bore holes for defects, replacement of bolts, and repair if necessary. We are issuing this AD to address the unsafe condition on these products.
At the applicable time identified in paragraphs (g)(1) or (g)(2) of this AD, remove the sheer bolts at FR36 and FR39, left hand and right hand, as identified in Dassault Service Bulletin 7X-379, dated February 29, 2016, and do a detailed visual inspection of the bore holes for defects, in accordance with Dassault Service Bulletin 7X-379, dated February 29, 2016.
(1) For airplanes with S/Ns 2 and 5: Before exceeding 4,100 flight cycles after the date of release to service after the first C-Check or within 3 months from the effective date of this AD, whichever occurs later.
(2) For airplanes other than those identified in paragraph (g)(1) of this AD: Before exceeding 4,100 flight cycles since the date of issuance of the original certificate of airworthiness or the original export certificate of airworthiness or within 3 months from the effective date of this AD, whichever occurs later.
(1) If, during any inspection required by paragraph (g) of this AD, any defect is found, before further flight, repair the affected areas, and replace the bolts at FR36 and FR39, in accordance with Dassault Service Bulletin 7X-379, dated February 29, 2016; except where Dassault Service Bulletin 7X-379, dated February 29, 2016, specifies to contact Dassault Aviation for instructions, before further flight, repair 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).
(2) If, during any inspection required by paragraph (g) of this AD, no defect is found, before further flight, replace the bolts at FR36 and FR39, in accordance with Dassault Service Bulletin 7X-379, dated February 29, 2016.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
