EXTERIOR LIGHTING

ELECTRICAL BONDING OF WHELEN FIN TIP ANTI-COLLISION LIGHT

1. PLANNING INFORMATION

A. EFFECTIVITY

This Service Bulletin is applicable to FALCON 2000EX aircraft with serial numbers 1 through 5 and 7

through 27 equipped with a WHELEN fin tip anti-collision light (without SATCOM fairing).

B. REASON

The investigation conducted on a Falcon 2000 aircraft that had been struck by lightning has shown

that the electrical bonding of the fin tip anti-collision light may not be sufficient under certain

circumstances, potentially resulting in damaging the aircraft wiring.

The purpose of this Service Bulletin is to improve the electrical bonding of the F2000EX fin tip anticollision light whose installation is similar to the F2000.

C. DESCRIPTION

After removing the fin tip fairing, the operation consists of the following:

• to install an electrical bonding strip in two parts between the anti-collision light and a rib of the

fin,

• to modify the shield connection of the wiring.

D. COMPLIANCE

Mandatory:

• This Service Bulletin is rendered mandatory by EASA Airworthiness Directive No. 2015-0006.

• As prescribed by the Airworthiness Authorities of the country of registration of the aircraft.

E. APPROVAL

This Service Bulletin covers DASSAULT AVIATION modification F2000EX M3036 that has 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: Refer to Service Bulletin Commercial Summary.

NOTE: These labor-hours only concern the work described in this Service Bulletin and do not include

other maintenance work that may be performed on this occasion.

2. ACCOMPLISHMENT INSTRUCTIONS

A. PRELIMINARY STEPS

(1) The aircraft must be in the maintenance configuration (Refer to TASK 20-00-00-910-801).

(2) Remove the screws attaching upper fin tip fairing (322A) (Refer to IPC fig. 55-30-40-10).

(3) Disengage upper fin tip fairing (322A), disconnect connector (322P) and remove upper fin tip

fairing (322A).

(4) Removal of the light unit assembly (Refer to IPC fig. 33-40-10-50):

• Remove the PR bead coating the retainer (item 380) without removing the flexible gasket

located underneath.

• Remove the retainer, glass cover and seal (items 380, 390 and 400).

• Remove the light unit assembly (screws item 130).

NOTE: Remove and discard gasket (item 420) if installed.

In accordance with fig. 1 of this SB:

B. ANTI-COLLISION LIGHT ELECTRICAL BONDING

In accordance with fig. 1:

(1) Cut out the run outs of the compound seal to obtain a plane mounting surface.

(2) Set the mounting-base bonding strip (item 1), equipped with plate (item 8), into place on the

fairing. Attach with two screws.

(3) Fold the tab of the strip to a 90° angle with respect to the fairing’s rib.

(4) Pin the strip assembly (items 2 and 3) to the fairing.

(5) Position the strip assembly (items 2 and 3) in contact against the RH side panel of the fairing and

on strip (item 1). If necessary, rework the shape of the strips to obtain proper contact.

(6) Remove the strip assembly (items 2 and 3).

(7) Install double-sided adhesive tape on the face coming in contact with bonding strip (item 1).

(8) Re-install strip assembly (items 2 and 3). Pin to hold in contact against the fairing.

(9) Install strip (item 1) over the strip assembly, pressing firmly at the contact area.

(10) Remove the strip assembly (items 1, 2 and 3).

(11) Counterdrill bonding strip (item 2) to a diameter of 0.1 in (2.5 mm). Disconnect the strips and

discard the adhesive tape, remove all remaining adhesive.

(12) Enlarge the holes drilled in the strips to a diameter of 0.126 in (3.2 mm). Assemble bonding strips

(items 1 and 2) using rivets (item 4). Coat the faces of the strips with covering sealant making a

bead at the contour edge with bead sealant.

(13) Clean the contact surfaces of the light unit assembly, of the strips, and of the fairing using MEK.

(14) Coat strip assembly (items 2 and 3) with interlaying sealant.

(15) Connect and safety connector (4LX) to the light unit.

DASSAULT AVIATION Proprietary Data
(16) Set the strip assembly and the light unit assembly into place in the fairing and attach the light

assembly to the fairing. Smooth out the PR in excess around the strips.

(17) Use a shim to wedge strip assembly (items 2 and 3) in contact against the fairing’s wall. Allow to

cure.

(18) Temporarily position the fairing at the fin tip and mark the location of strip (item 3).

(19) Strip the paint off the fin tip rib at the location marked for strip (item 3). Protect the stripped area

with alodine.

(20) Install the seal, glass cover, and the retainer (Refer to IPC fig. 33-40-10-50 , items 400, 390 and

380).

(21) Apply bead sealant around the retainer plate.

C. MODIFYING THE WIRING

Modify the shield connection in accordance with instructions depicted hereafter and fig. 2.

Dimension A:

• Connector with front extraction: 1.38 in (35 mm).

• Connector with rear extraction: 1.97 in (50 mm).

Self–soldering sleeves must be staggered at the extremity of the wiring assemblies so as to prevent a

bulge on the bundle.

INSTALLING SELF-SOLDERING SLEEVES

• After stripping the shielded cable and the ground lead wire, unwind the shielding braid of cable

without overlapping the shielding strands.

• Position the self-soldering sleeve on the stripped part of the cable.

• Insert the stripped part of the ground lead wire on the inside of the solder preform. Make sure

that the ground lead wire is installed against the guide provided for this purpose.

• With hot air or infrared generator equipped with an appropriate reflector, start heating the small

diameter of the self-soldering sleeve, then move up to the solder preform until it melts and flows.

Complete the operation on the large side of the self-soldering sleeve. It is recommended to

Revision 1 Page 5 / 10

DASSAULT AVIATION Proprietary Data
position the solder preform at a 90° angle maximum in relation to the heat source. The solder

must always be visible to the operator.

• The insulating sheath of the shielded cable must not be blistered nor burnt.

D. FINAL STEPS

(1) Use a permanent ink pen to record the number of this Service Bulletin on "Service Bulletin

Compliance" label (item 7).

(2) Use interlaying sealant to bond the "Service Bulletin Compliance" label (item 7) to the inner skin

of the fairing next to the P/N.

(3) Place upper fin tip fairing (322A), connect connector (322P) and attach upper fin tip fairing

(322A).

(4) Measure the electrical bonding across the anti–collision light retainer plate and the reference point

located in the mechanic’s servicing compartment (Refer to TASK 20-20-00-910-801).

The measured value must not exceed 2 mΩ

(5) Perform the operational test of the upper anti-collision light (Refer to TASK 33-40-00-710-801).
