AD 2005-18-14 Airworthiness Directives; Avions Marcel Dassault-Breguet Model Falcon 10 Airplanes

Models named: Falcon 10. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to all Avions Marcel Dassault-Breguet Model Falcon 10 airplanes, certificated in any category.

You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. Restatement of the Requirements of AD 2005-07-23 Repetitive Inspections, or Airplane Flight Manual (AFM) Revision and Placard Installation (f) Within 14 days after April 26, 2005 (the effective date of AD 2005-07-23), perform the actions specified in either paragraph (f)(1) or (f)(2) of this AD: (1) Revise the Limitations section of the Dassault Aviation Falcon 10 AFM, and install a placard in the flight deck, to include the following information. “Flights into known or forecasted icing conditions are prohibited.” The AFM revision may be done by inserting a copy of this AD into the AFM. Install the placard on the pedestal in clear view of the pilot. (2) Determine the part number of each flexible hose installed in the slat anti-icing system, perform a detailed inspection of the internal walls of the hoses for delamination, and perform any applicable corrective action, by accomplishing all of the applicable actions specified in the Accomplishment Instructions of Dassault Alert Service Bulletin F10-A312, dated February 25, 2005. If the part number for any hose cannot be determined, before further flight, replace that hose with a hose having part number (P/N) FAL1005D. Any corrective action must be done before further flight. Repeat the detailed inspection thereafter at intervals not to exceed 60 flight cycles or 3 months, whichever is first, until the actions required by paragraph (i) of this AD are accomplished. Note 1: When a statement identical to that in paragraph (f)(1) of this AD has been included in the general revision of the AFM, the general revision may be inserted into the AFM, and the copy of this AD may be removed from the AFM. Note 2: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.” (g) For airplanes on which the actions described in paragraph (f)(1) of this AD are performed, doing the actions described in paragraph (f)(2) of this AD is terminating action for the requirements of paragraph (f)(1) of this AD. Once the initial detailed inspection specified in paragraph (f)(2) of this AD is performed, the AFM limitation and placard required by paragraph (f)(1) of this AD may be removed. New Requirements of This AD New Inspections and Intervals (h) For airplanes not operated under the limitation in paragraph (f)(1) of this AD, before the next 10 flight cycles in which the slat anti-icing system is activated after the effective date of this AD: Do a boroscope inspection of each flexible hose installed in the slat anti-icing system. Do all the inspections and any applicable corrective action (including replacing the hose with a new hose having P/N FAL1005D), by accomplishing all of the applicable actions specified in the Accomplishment Instructions of Dassault Alert Service Bulletin F10-A312, Revision 1, dated June 27, 2005. Any corrective action must be done before further flight. Repeat the inspection thereafter at intervals not to exceed 10 flight cycles in which the slat anti-icing system is activated. Doing this inspection terminates the repetitive inspection requirements of paragraph (f)(2) of this AD. (i) For airplanes on which the actions described in paragraph (f)(1) of this AD are performed, doing the actions described in paragraph (h) of this AD is terminating action for the requirements of paragraph (f)(1) of this AD. Once the initial boroscope inspection specified in paragraph (h) of this AD is performed, the AFM limitation and placard required by paragraph (f)(1) of this AD may be removed. AFM Revision (j) For airplanes not operated under the limitation in paragraph (f)(1) of this AD, before further flight after the effective date of this AD: Revise the Limitations section of the Dassault Aviation Falcon 10 AFM, to include the following information. “After each flight in which the slat anti-ice system is activated, inform maintenance.” The AFM revision may be done by inserting a copy of this AD into the AFM. Note 3: When a statement identical to that in paragraph (j)(1) of this AD has been included in the general revision of the AFM, the general revision may be inserted into the AFM, and the copy of this AD may be removed from the AFM. Optional Replacement (k) For airplanes not operated under the limitation in paragraph (f)(1) of this AD: Replacing the flexible hose installed in the slat anti-icing system with a new hose having P/N FAL1007, in accordance with the Accomplishment Instructions of Dassault Service Bulletin F10-313, dated August 10, 2005, terminates the repetitive inspection intervals of paragraph (h) and (f)(2) of this AD. Repeat the replacement thereafter at intervals not to exceed 90 flight cycles in which the slat anti-icing system is activated. Reporting Requirement (l) At the applicable time specified in paragraph (l)(1) or (l)(2) of this AD: After performing any inspection required by this AD, submit a report of the findings (positive and negative) of the inspection to: Dassault Falcon Jet, Attn: Service Engineering/Falcon 10, fax: (201) 541-4700. The report must include the airplane serial number, the location of the hose (inboard or outboard), the number of flight hours since hose installation, the number of cycles in icing conditions, and the manufacturing date and batch number of the hose. Submission of the Service Bulletins Compliance card, which is attached to Dassault Alert Service Bulletin F10-A312, is an acceptable method of complying with this requirement. Under the provisions of the Paperwork Reduction Act of 1980 (44 U.S.C. 3501 et seq. ), the Office of Management and Budget (OMB) has approved the information collection requirements contained in this AD and has assigned OMB Control Number 2120-0056.

This AD results from a report of in-service delamination of a flexible hose in the slat anti-icing system at a time earlier than previously reported. We are issuing this AD to prevent collapse of the flexible hoses in the slat anti-icing system, which could lead to insufficient anti-icing capability and, if icing is encountered in this situation, could result in reduced controllability of the airplane.
