F2000/2000EX Main Landing Gear Shock Absorber Internal Damage

— Ron Grose

Announced at the Falcon M&O Seminar in Monaco, during the overhaul of a Falcon 2000 main landing gear, the three screws used to attach the metering pin flow restrictor inside the main landing gear (MLG) shock absorber were found broken. Inspections of additional shock absorbers have revealed more broken or missing hardware.

To correct this issue, Dassault will be releasing mandatory service bulletins SBF2000-366 & -367 in the coming weeks. SBF2000-366 will give instructions to perform a borescope inspection of the interior of both MLG shock absorbers for loose or missing hardware. SBF2000-367 will repair the shock absorbers by installing new parts to secure the attachment hardware.

These service bulletins will be mandatory for both EASA and FAA ADs. This will affect all of the Falcon 2000 model aircraft and many of the Falcon 2000EX model aircraft. This issue is explained in FSA2000-32-10-06 and FSA2000EX-32-10-02.

Duncan Aviation facilities in Lincoln, NE, and Battle Creek, MI, have technicians trained to handle these inspections and repairs for your aircraft. Please contact Mark Goertzen in Lincoln at 800.228.4277 ext. 1511, Ron Grose in Lincoln ext. 1640 or Kevin Bornhorst in Battle Creek at 800.525.2376 ext. 8482 for more information.

Falcon 50, 900 and 2000 Aileron Actuator Hose Chafing

— Mark Goertzen

The next time you have the aileron servo actuator wing access panels off (panel 550AB), inspect the actuator hydraulic supply hoses that come through the rib located outboard of the actuator. Duncan Aviation technicians have found the lower hose has been chafing into the rib. To fix, loosen the hose and re-clock it to put the curve of the hose away from the rib in full aileron travels. Contact Dassault if any chafing is found because this rib is considered primary structure. Also do a general visual inspection (GVI) of the braiding on the hose.

Please contact Mark Goertzen in Lincoln at 800.228.4277 ext. 1511, Ron Grose in Lincoln ext. 1640 or Kevin Bornhorst in Battle Creek at 800.525.2376 ext. 8482 for more information.

F2000/2000EX Inboard Wing Leading Edges

— Mark Goertzen

Next time you have the inboard leading edges off your F2000, note the position of the clamp joining the two wing heat anti-ice tubes. If the clamp is installed in a position where the clasp is facing forward, it will begin chafing into the leading edge’s aft close-out skin. Rotating the clamp where the clasp is either in the up or down position provides clearance in this area.

“A” and “B” Inspection Interval Extension Service Bulletin

— Tim Klenke

Dassault released SB F900EX-333 (900EX & DX models) and SB F2000EX-166 (2000EX models), which extends the inspection intervals of “A” and “B” inspections for the aircraft. The new interval for the “A” inspection is 8 months/400 hours and 1,600 hours for the “B” inspection. The “C” inspection interval is unchanged and remains at 6 years. All operators will be expected to incorporate these new intervals within the next two years as stated in the service bulletins.

New service bulletins for the F900 and F2000 model aircraft will be released in the coming months allowing these aircraft to extend their inspection intervals also.

Please call Duncan Aviation for eligibility and enrollment requirements for your next maintenance event.
