INSTALLATION OF PROTECTIVE WRAPS ON BRAKING SYSTEM FLEXIBLE HOSES

1. PLANNING INFORMATION A. EFFECTIVITY This Service Bulletin is applicable to FALCON 2000 aircraft with serial numbers 1 through 231 which are not equipped with:

• LH main landing gear P/N D23345000-7 Amdt B,

• RH main landing gear P/N D23346000-7 Amdt B, and which have not implemented DASSAULT AVIATION modification F2000 M3237.

B. REASON Several cases of hydraulic fluid leaks recently occurred on the MLG braking system hoses, due to chafing between the external steel braids and the main landing gear torque link.

The purpose of this Service Bulletin is to prevent damage to the steel braid and torque link by installing a spiral wrap made of Teflon, in order to avoid:

• any cancellation of flight if leakage occurs,

• and any additional maintenance workload on damaged torque link and braking system hoses.

C. DESCRIPTION The operation consists in:

• inspecting each MLG brake external steel braid hose and,

• installing a spiral wrap made of Teflon to each MLG brake external steel braid hose (two per main landing gear leg).

D. COMPLIANCE Mandatory:

• It is anticipated that this Service Bulletin will be rendered mandatory by an EASA Airworthiness Directive.

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

E. APPROVAL This Service Bulletin covers DASSAULT AVIATION modification F2000 M3237 which 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:

• 1 hour for the modification.

• No specific access.

2. ACCOMPLISHMENT INSTRUCTIONS A. PRELIMINARY STEPS

(1) The aircraft must be in the maintenance configuration (refer to Standard Practices, procedure 20-000 (Refer to TASK 20-00-00-910-801)).

B. PROCEDURE

(1) In the cockpit, make sure that the park brake handle is released.

(2) Inspect each braking system hose (A-fig. 1):

• If no damage is found, or

• If some strands of various braids are broken and/or damaged but if elastomer hose cannot be seen (see fig. 2, detail A), install a protective wrap (1-fig. 1) on the braking system hose (A-fig. 1) as follows:

CAUTION: TAKE ALL PRECAUTIONS TO AVOID STRETCHING OR BENDING OVER A

TIGHT RADIUS A BRAKING SYSTEM HOSE, WHEN INSTALLING A PROTECTIVE WRAP.

• Place the protective wrap approximately near the hose to be protected and cut it to length (hose length or slightly more).

NOTE: A 24 in. (600 mm) long protective wrap is required to protect each braking system hose.

• Slide the hose identification ring fully down.

• Fit the top of the protective wrap below the torque link lower guide (B-fig. 1).

• Once 4 to 6 in. (10 to 15 cm) of protective wrap are in place, slide the wrap up through the torque link’s lower guide (B-fig. 1), rotating the sheath so as to loosen friction along the hose.

• Repeat step (c) for the next spiral section, passing the wrap through the guides (B-fig. 1) and (C-fig. 1) up to the top of the hose, below the bridge (D-fig. 1).

• Wrap the remaining section around the bottom of the hose and cut any excess length, if necessary.

• If all strands in same braid are broken and if elastomer hose can be seen (see fig. 2, detail B), replace the braking system hose(A-fig. 1) according to Dassault Aviation Service Bulletin F2000-368 “Landing gear - Main landing gear - Improvement of braking hoses and corresponding assemblies”.
