ATA SYSTEM: 2812 NUMBER: 84-28-15

BOMBARDIER AEROSPACE REGIONAL AIRCRAFT CONSIDER THIS

SERVICE BULLETIN TO BE PARTICULARLY SIGNIFICANT AND

URGES OPERATORS TO PROMPTLY EVALUATE THE CONTENTS

SUBJECT: Fuel System - Center Wing - Engine Fuel Feed Installation - Introduction of

New Tube to Eliminate Fouling Condition - ModSum 4-113762

B. Reason

Problem: Operators have reported a fouling condition between engine fuel feed line

82822143-003 and the wing structure at station Y-157.825 (right side fuel

tank).

Other locations have been reported with inadequate clearance between

the fuel pipe and structure. In the event of a lightning strike, a spark could

be produced at the fouling interface between pipe and structure.

Solution: This service bulletin introduces ModSum 4-113762 which replaces five

existing fuel lines (two in the left wing and three in the right wing and

supporting brackets) with new fuel lines and supporting brackets.

The new fuel lines and brackets are designed to include different

geometric angles to make sure contact with the wing structure is

eliminated and adequate clearance is maintained. In addition, teflon

tubing is wrapped around one motive flow line and scavenge lines in each

fuel tank (left and right side) at specific locations as part of the modification.

C. Description

The procedures in this service bulletin give the instructions to do the tasks that

follow:

- aircraft is put into standard configuration for maintenance

- aircraft electrical power is removed

- the nose landing gear lock is engaged

- the main landing gear lock pins are installed thru each main gear and main gear

door mechanism

- the fuel tanks are drained

- the engines are supported then specific fuel tank access panels (center and outer

wing) are removed

- residual fuel is mopped up and the tank is vented

- five existing fuel feed tube assemblies, four existing brackets, cushion clamps and

related hardware are removed

- five new fuel feed lines and new brackets are installed and secured using kept

hardware

- the reworked ribs in each wing are re-identified with a new part number

- teflon sleeves are installed around a motive fuel line in each outer wing tank

- the new lines are pressure tested
