 1 . PLANNING INFORMATION

A . EFFECTIVITY

This Service Bulletin is applicable to:

– FALCON 2000EX aircraft with serial numbers 1 through 600 (F2000EX, F2000EX EASy),

– FALCON 2000EX aircraft with serial numbers 601 through 700 (F2000DX),

which have not previously implemented DASSAULT AVIATION modification F2000EX

M3072.

 B . REASON

An analysis of rare high-speed runway excursions has revealed that, in case of a main landing

gear leg failure due to overloads, the subsequent wing damage may cause a potential fuel

spill.

The purpose of this Service Bulletin is to prevent such a fuel spill in the event of such an

exceptional occurence by installing a sealed boundary between ribs No. 4 and 5 in front of

the rear wing spar.

 C . DESCRIPTION

The operation consists in:

– removing the structural removable lower wing panel,

– installing a drainage capability,

– installing a boundary between ribs No 4 and 5,

– applying a sealant around the boundary,

– performing a test for leakage,

– replacing the instruction placards on the wings and on the refueling door (186CR).

The Accomplishment Instructions and the tests are included in the five Appendices to this

Service Bulletin.

 D . COMPLIANCE

Mandatory:

Compliance with this Service Bulletin should be done no later than 12 years and 6 months

of its release date.

It is anticipated that this Service Bulletin will be rendered mandatory by an EASA

Airworthiness Directive. The Airworthiness authorities of other countries may also elect to

mandate compliance with this Service Bulletin and compliance timelines will be established

by those authorities.

Each person applying this Service Bulletin must have successfully completed a training

program. For more details refer to the training section of paragraph F.

 E . APPROVAL

This Service Bulletin covers DASSAULT AVIATION modifications F2000EX M3072 which has

been approved by EASA and M3206 which have been approved under the authority of DOA

nr. EASA.21J.051.

The technical content of this document is approved under the authority of DOA

nr. EASA.21J.051.

 F . LABOR

Estimated labor–hours:

– Access time: 300 hours

– Modification: 300 hours

– 40 hours for paint touch (including lower wing panels and upper wings reworked areas)

NOTE: These labor–hours only concern the work described in this Service Bulletin and do

not include other maintenance work which may be performed on this occasion.

NOTE: The Service Bulletin instructions contained in the five APPENDICES constitute

complex structural rework activity that should only be accomplished at Service

Centers that have relevant experience working on Falcon aircraft and have a

high level of competency in the following areas:

– Work on primary structure.

– Metal work.

– Precision adjustment.

– Non-destructive-Testing (NDT) for cracks.

– Use of S-class screws and repair dimensions.

Failure to utilize an experienced Service Center with a high level of proficiency

in the above disciplines and specialized training in the operations covered

hereby, could result in inadvertent damage during the Service Bulletin

procedure, possibly requiring extensive aircraft repairs.

TRAINING: Each person applying this Service Bulletin must have successfully completed a

training program. This training program consists of applying this Service Bulletin in the

person’s facility under the supervision of a trainer from Dassault Aviation, and/or Dassault

Aircraft Services (DAS) personnel that have received training from Dassault Aviation.

Each facility applying this Service Bulletin must maintain capable individuals on staff that have

successfully completed the Dassault training program prior to attempting this modification.

However, it is acceptable that a person from a facility that has successfully completed the

training program to be designated to serve as a trainer for that facility. As a consequence,

it is the responsibility of each maintenance facility applying this Service Bulletin to define an

internal training program of its technicians and maintain familiarization of the application of

the SB to maintain the required knowledge over the years.
