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 Aviation Service Bulletin(s).

B. Reason

1. Condition:

It was observed that on aircraft in−house at completions that the therapeutic oxygen hose installations were non−compliant to the applicable installation standards.

2. Evidence:

− Minimum spacing between oxygen hose and the electrical harness was not respected.

− Positive separation mechanisms have not been implemented.

− Appropriate protective barriers were not installed.

3. Objective/Benefit:

This Service Bulletin provides instructions to inspect the minimum clearance between therapeutic oxygen hose and wire harness, and if required, instructs to install appropriate hose and harness protective devices to make sure adequate component protection and positive separation.

Refer to SPM−WM 20−14−00−02 and Figure 3.

(13) Inspect the harnesses surrounding the oxygen hose for damage (damaged wire sheathing, cut or nicked wires), if necessary repair the harness as per SPM−WM 20−12−10−02 and refer to Figure 3.

(14) If the clearance between the wiring harness and the oxygen hose is less than

0.5 in (12.70 mm), install the teflon cable wrap (05−124) or Nomex sleeving (Roundit 2000NX), on wiring harness. Refer to SPM−WM 20−50−00−400−806 and Figure 3.
