1. PLANNING INFORMATION
A. EFFECTIVITY
This Service Bulletin is applicable MYSTERE-FALCON 900 aircraft equipped with a WHELEN fin tip
anti-collision light (without SATCOM fairing) per Service Bulletin F900-182 (M1682).
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 MYSTERE-FALCON
900 fin tip anti-collision 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,
• to reroute the wiring as required in accordance with the aircraft’s serial number.
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 MF900 M5381 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

NOTE: The wiring will be re-routed in accordance with the instructions of paragraph 2.F.
(3) Machine the cutout in rib 3 in accordance with fig. 8.
C. ANTI-COLLISION LIGHT ELECTRICAL BONDING
In accordance with fig. 1 or fig. 2 depending on the P/N of the existing fairing:
(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 shim (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).

(18) Strip the paint off the fin tip rib at the location marked for strip (item 3). Protect the stripped area
with alodine.
D. MODIFYING THE WIRING
Modify the shield connection in accordance with instructions depicted hereafter and using fig. 3, fig. 4
and fig. 5 in accordance lights’ installation on the aircraft.
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
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.
E. RE-ROUTING THE WIRING WITH WIRING ROUTED OVER RIB 2
