Airworthiness Directive · Amendment 39-15188 · Avions Marcel Dassault-Breguet Model Falcon 10 Airplanes
Avions Marcel Dassault-Breguet Model Falcon 10 Airplanes
Superseded. A later AD replaced this one: AD 2008-19-08. Comply with the one in force.
This AD applies to all Avions Marcel Dassault-Breguet Model Falcon 10 airplanes.
The FAA is superseding an existing airworthiness directive (AD), which applies to all Avions Marcel Dassault-Breguet Model Falcon 10 airplanes. That AD currently requires either revising the airplane flight manual (AFM) and installing a placard in the flight deck to prohibit flight into known or forecasted icing conditions, or repetitively inspecting for delamination of the flexible hoses in the wing (slat) anti-icing system and performing corrective actions if necessary. That AD also provides optional terminating action for the repetitive inspections. This new AD mandates the previously optional terminating action. 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.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 14 days after April 26, 2005 (the effective date of AD 2005-07-23, which was superseded by AD 2005-18-14), perform the actions specified in either paragraph (f)(1) or (f)(2) of this AD: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.
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 September 26, 2005 (the effective date of AD 2005-18-14), do a borescope 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 borescope 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.
For airplanes not operated under the limitation in paragraph (f)(1) of this AD: Before further flight after September 26, 2005, 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) 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.
Within 330 flight hours or 7 months after the effective date of this AD, whichever occurs first: Replace the flexible hoses installed in the slat anti-icing system with new hoses having P/N FAL1007, in accordance with the Accomplishment Instructions of Dassault Service Bulletin F10-313, Revision 1, dated May 10, 2006. This replacement terminates the requirements of paragraphs (f) through (j) of this AD. For airplanes previously operated under the limitation in paragraph (f)(1) of this AD: When the hoses have been replaced, the AFM limitation and placard required by paragraph (f)(1) of this AD may be removed. Repeat the hose replacement at intervals not to exceed 700 flight cycles.
(l) Replacement of a hose before the effective date of this AD in accordance with Dassault Service Bulletin F10-313, dated August 10, 2005, is acceptable for compliance with the requirements of paragraph (k) of this AD.
