Dassault Model Mystere-Falcon 50 and 900, and Falcon 900EX Airplanes; and Model Falcon 2000 and Falcon 2000EX Airplanes
This AD applies to the airplanes identified in Table 1 of this AD, certificated in any category.
| Dassault model— | Serial Nos.— |
|---|---|
| Mystere-Falcon 50 airplanes | 2 through 344 inclusive. |
| Mystere-Falcon 900 airplanes | 1 through 202 inclusive. |
| Falcon 900EX airplanes | 1 through 96 inclusive and 98 through 154 inclusive. |
| Falcon 2000 airplanes | 1 through 223 inclusive. |
| Falcon 2000EX airplanes | 1 through 69 inclusive. |
The FAA is adopting a new airworthiness directive (AD) for certain Dassault Model Mystere-Falcon 50 and 900, and Falcon 900EX airplanes; and Model Falcon 2000 and Falcon 2000EX airplanes. This AD requires an inspection of the identification plates of the outboard slats to determine the type of identification plates and the part numbers. For certain airplanes, this AD also requires a revision to the Limitations and Normal Procedures sections of the airplane flight manual to provide procedures for operation in icing conditions; and replacement of the anti-icing manifold with an anti-icing manifold of the correct type design if necessary. For certain airplanes, this AD also requires related investigative and corrective actions if necessary. This AD results from a finding that the outboard slats for Model Mystere-Falcon 50 airplanes have been erroneously authorized, in limited cases, as interchangeable for use on Model Mystere-Falcon 900 and Falcon 900EX airplanes; and Model Falcon 2000 and Falcon 2000EX airplanes. We are issuing this AD to prevent failure of the anti-icing manifold of the outboard slats, which could result in loss of control of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
The term “service bulletin,” as used in this AD, means the Accomplishment Instructions of the service bulletins identified in Table 2 of this AD, as applicable. Although the service bulletins referenced in Table 2 of this AD specify to submit certain information to the manufacturer, this AD does not include that requirement.
| Dassault Service Bulletin— | Dated— | For model— | For the actions specified in— |
|---|---|---|---|
| F2000-331 | January 30, 2006 | Falcon 2000 airplanes | Paragraph (h) of this AD. |
| F2000EX-91 | January 30, 2006 | Falcon 2000EX airplanes | Paragraph (h) of this AD. |
| F50-475 | January 30, 2006 | Mystere-Falcon 50 airplanes | Paragraph (g) of this AD. |
| F50-478 | January 30, 2006 | Mystere-Falcon 50 airplanes | Paragraph (g)(2) of this AD. |
| F900-370 | January 30, 2006 | Mystere-Falcon 900 airplanes | Paragraph (h) of this AD. |
| F900EX-273 | January 30, 2006 | Falcon 900EX airplanes | Paragraph (h) of this AD. |
For Model Mystere-Falcon 50 airplanes: Within 330 flight hours or 7 months after the effective date of this AD, whichever occurs first, inspect the identification plates of the outboard slats to determine the type of identification plates and the part numbers (P/Ns), in accordance with the applicable service bulletin. A review of airplane maintenance records is acceptable in lieu of the inspection if the type of identification plate and the part numbers of the outboard slats can be determined conclusively from that review. If a “type 3” identification plate is installed and mentions “REP,” “WILMINGTON,” “LITTLE ROCK,” or any other repair station, or if the conformity of the slat with the airplane's type design cannot be positively confirmed, before further flight, do a “go-no-go” diameter check of the air distribution holes of the manifold using a drill bit shank, in accordance with the applicable service bulletin. If the drill bit shank can be inserted through the air distribution holes of the manifold, or if a “type 1” identification plate is installed and inscribed with P/N FGFB134XX or P/N FGFB144XX, or if a slat has multiple identification plates and the vertical field of the most recent plate is inscribed with “F900” or “MF900,” do the actions specified in paragraphs (g)(1) and (g)(2) of this AD.
(1) Before further flight after the inspection required by paragraph (g) of this AD: Revise the Limitations and Normal Procedures sections of the Dassault Mystere-Falcon 50 Airplane Flight Manual (AFM), DTM813, to include the information in Dassault Temporary Change (TC) 61, dated January 27, 2006, as specified in the TC; or revise the Limitations and Normal Procedures sections of the Dassault Mystere-Falcon 50EX AFM, FM813EX, to include the information in Dassault TC 75, dated January 27, 2006, as specified in the TC; as applicable. These TCs introduce procedures for operation in icing conditions. Operate the airplane according to the limitations and procedures in the applicable TC.
Note 1: This may be done by inserting a copy of TC 61 or TC 75 in the AFM, as applicable. When the TC has been included in the general revisions of the AFM, the general revisions may be inserted in the AFM, provided that the relevant information in the general revision is identical to that in TC 61 or TC 75, as applicable.
(2) Within 1,530 flight hours after accomplishing the inspection required by paragraph (g) of this AD: Replace the anti-icing manifold with an anti-icing manifold of the correct type design, by accomplishing all of the actions specified in the applicable service bulletin, except as provided by paragraph (f) of this AD. Accomplishing the replacement terminates the requirements of paragraph (g)(1) of this AD. After the replacement has been done, the AFM limitation required by paragraph (g)(1) of this AD may be removed from the AFM.
For Model Mystere-Falcon 900 and Falcon 900EX airplanes, and Model Falcon 2000 and Falcon 2000EX airplanes: Within 330 flight hours or 7 months after the effective date of this AD, whichever occurs first, inspect the identification plates of the outboard slats to determine the type of identification plates and the part numbers, and do all related investigative and corrective actions, by accomplishing all of the actions specified in the service bulletin, as applicable, except as provided by paragraph (f) of this AD. Do all applicable related investigative and corrective actions before further flight. A review of airplane maintenance records is acceptable in lieu of the inspection if the type of identification plate and the part numbers of the outboard slats can be determined conclusively from that review.
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.
