Airworthiness Directive · Amendment 39-14466 · Dassault Model Falcon 2000 and Falcon 2000EX Airplanes
Dassault Model Falcon 2000 and Falcon 2000EX Airplanes
This AD applies to the Dassault airplanes in Table 1 of this AD, certificated in any category; equipped with a third crew member passenger-type oxygen mask on the cockpit ceiling; excluding those airplanes on which Dassault Modification M2739 has been done in production.
| Model | Serial numbers |
|---|---|
| (1) Falcon 2000 airplanes | 1 through 226 inclusive. |
| (2) Falcon 2000EX airplanes | 1 through 64 inclusive |
The FAA is adopting a new airworthiness directive (AD) for certain Dassault Model Falcon 2000 and Falcon 2000EX airplanes. For all airplanes, this AD requires, among other actions, doing an inspection for damage of the feeder cables, and corrective actions if necessary; and installing a protective plate on the feeder cables. For certain airplanes, this AD also requires re-routing the wiring on the cockpit protector; drilling holes in the cockpit protector; and clamping the feeder cables; as applicable. This AD results from a drawing review and further associated inspections that highlighted a potential chafing risk between the third crew member's oxygen mask box and feeder cables routed in the area. We are issuing this AD to prevent chafing between the subject oxygen mask box and the adjacent feeder cables, which could generate smoke or fire in the cockpit that could be fanned by oxygen leakage from the oxygen mask box.
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 applicable service bulletin in Table 2 of this AD.
| Dassault service bulletin— | Dated— | For model— |
|---|---|---|
| (1) F2000-332 | December 22, 2005 | Falcon 2000 airplanes. |
| (2) F2000EX-92 | December 22, 2005 | Falcon 2000EX airplanes. |
Within 30 days or 30 flight cycles after the effective date of this AD, whichever occurs first, do the applicable actions in Table 3 of this AD in accordance with the service bulletin.
| For— | Required actions |
|---|---|
| (1) All airplanes | Coat nuts and rivets with epoxy resin. |
| (2) All airplanes | Do a general visual inspection for damage of the feeder cables coming from the essential and A1 buses. |
| (3) Model Falcon 2000EX airplanes, serial number 6 and 28 through 64 inclusive | Drill holes in the cockpit protector located between the headline and the skin, and clamp the feeder cables coming from the essential, A1, and A2 buses. |
| (4) All Model Falcon 2000 airplanes and for Model Falcon 2000EX airplanes, serial numbers 1 through 5 inclusive and 7 through 27 inclusive | Re-route the wiring on the cockpit protector, and bond the applicable supports with epoxy resin. |
| (5) All airplanes | Install a protective plate on the feeder cables. |
Note 1: For the purposes of this AD, a general visual inspection is: “A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made from within touching distance unless otherwise specified. A mirror may be necessary to ensure visual access to all surfaces in the inspection area. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or droplight and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked.”
If any damaged feeder cable is detected during the inspection required by paragraph (g)(2) of this AD, before further flight, do the applicable corrective actions in accordance with the service bulletin.
(i) Although the service bulletins referenced in this AD specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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.
