Airworthiness Directive · Amendment 39-19017 · Ice and rain protection
Dassault Aviation Airplanes
This AD applies to Dassault Aviation Model FALCON 2000 and FALCON 2000EX airplanes, certificated in any category, all serial numbers.
We are adopting a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 2000 and FALCON 2000EX airplanes. This AD was prompted by reports of ice accretion on the airplane wing due to the failure of certain anti-ice piccolo tubes in the wing outboard slats. This AD requires repetitive inspections of each anti-ice piccolo tube and corrective action if necessary. We are issuing this AD to address the unsafe condition on these products.
(1) For the purpose of this AD, an affected anti-ice piccolo tube meets at least one of the conditions specified in paragraphs (g)(1)(i) and (g)(1)(ii) of this AD.
(i) Has part number (P/N) FGFB725102 (left-hand side (LH)) or P/N FGFB726102 (right-hand side (RH)).
(ii) Is installed on a wing outboard slat having a part number identified in table 1 to paragraph (g)(1)(ii) of this AD.

(2) If the outboard slat part number is identified in table 2 to paragraph (g)(2) of this AD, the anti-ice piccolo tube is not affected because the outboard slat has already been retrofitted with a new stiffened anti-ice piccolo tube, and no action is required by this AD for that piccolo tube.

If an anti-ice piccolo tube has been determined to be affected, as specified in paragraph (g) of this AD: At the applicable time specified in table 3 to paragraph (h) of this AD, do an endoscopic inspection for discrepancies, i.e., manufacturing defects, cracking, and loss of material in the welded parts of each affected anti-ice piccolo tube, in accordance with the Accomplishment Instructions of Dassault Service Bulletin F2000-431, Revision 1, dated June 6, 2016; or Service Bulletin F2000EX-391, Revision 1, dated June 6, 2016; as applicable. Repeat the endoscopic inspection thereafter at intervals not to exceed those specified in table 3 to paragraph (h) of this AD, until the modification specified in paragraph (k) of this AD is done.
| Airplane model | Initial inspection | Repetitive inspection intervals |
|---|---|---|
| FALCON 2000 airplanes | Prior to exceeding 2,000 flight cycles since the airplane's first flight, or within 1,000 flight cycles after the effective date of this AD, whichever occurs later | 2,000 flight cycles. |
| FALCON 2000EX airplanes | Prior to exceeding 1,000 flight cycles since the airplane's first flight, or within 500 flight cycles after the effective date of this AD, whichever occurs later | 1,000 flight cycles. |
If any discrepancy is found during any inspection required by paragraph (h) of this AD: Before further flight, replace the affected anti-ice piccolo tube with a new or serviceable part, and replace or re-identify the affected wing outboard slat as applicable, in accordance with the Accomplishment Instructions of Dassault Service Bulletin F2000-431, Revision 1, dated June 6, 2016; or Service Bulletin F2000EX-391, Revision 1, dated June 6, 2016; as applicable.
Although Dassault Service Bulletin F2000-431, Revision 1, dated June 6, 2016; and Service Bulletin F2000EX-391, Revision 1, dated June 6, 2016; specify to submit a report of crack findings to Dassault, this AD does not require a report.
Modification of an airplane by installing a new or serviceable anti-ice piccolo tube, and replacing or re-identifying the affected wing outboard slat, terminates the repetitive inspections required by paragraph (h) of this AD, if done in accordance with the Accomplishment Instructions of Dassault Service Bulletin F2000-431, Revision 1, dated June 6, 2016; or Service Bulletin F2000EX-391, Revision 1, dated June 6, 2016; as applicable.
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.
