Airworthiness Directive · Amendment 39-14048 · Dassault Model Falcon 10 Series Airplanes
Dassault Model Falcon 10 Series Airplanes
Superseded. A later AD replaced this one: AD 2005-18-14. Comply with the one in force.
This AD applies to all Dassault Model Falcon 10 series airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Dassault Model Falcon 10 series airplanes. This AD requires revising the Limitations section of the airplane flight manual (AFM) to include a statement prohibiting flight into known or forecasted icing conditions, and installing a placard in the flight deck. In lieu of the AFM revision and placard installation, this AD allows identifying the part number of each flexible hose in the wing anti-icing system, performing repetitive detailed inspections of each hose for delamination, and performing corrective actions if necessary. This AD is prompted by a report of delamination of the internal wall of a flexible hose in the wing anti-icing system. We are issuing this AD to prevent collapse of the flexible hoses in the wing 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 the effective date of this AD, 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 wing 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.
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) are performed, doing the actions described in paragraph (f)(2) is terminating action for the requirements of paragraph (f)(1). Once the initial detailed inspection specified in paragraph (f)(2) is performed, the AFM limitation and placard required by paragraph (f)(1) may be removed.
At the applicable time specified in paragraph (h)(1) or (h)(2) of this AD: After performing any detailed inspection required by paragraph (f)(2) of this AD, submit a report of the findings (positive and negative) of the detailed 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 form, which is attached to the alert service bulletin, 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.
(1) If the detailed inspection was done after the effective date of this AD: Submit the report within 30 days after the inspection.
(2) If the detailed inspection was done prior to the effective date of this AD: Submit the report within 30 days after the effective date of this AD.
