MODIFICATION - PRIMARY DC-POWER SYSTEM - REROUTING OF THE WIRING

HARNESS AT PRESSURE BULKHEAD FS669.759

1. PLANNING INFORMATION

A. Effectivity

BD−100−1A10 aircraft, Serial No. 20003 to 20382, 20384 and 20386.

All other BD−100−1A10 aircraft were scheduled for the modification in production.

NOTE: The instructions given in this Service Bulletin are only applicable to the

systems and parts installed at the time of delivery of the aircraft or as

changed by Bombardier Aerospace Service Bulletin(s).

Before you do this bulletin, examine all STC, STA or equivalent action

changes to make sure that this bulletin can be completed.

B. Reason

In some instances, it was found that a wiring harness, in the aft equipment bay, was

in contact with the hydraulic line. This had resulted in wear on the electrical

harness. There is a small possibility that this could eventually cause an electrical

short circuit or a system malfunction.
