## Description **Group 1-2: 1. CONCURRENT REQUIREMENTS**  Refer to data module SB B787-A-35-00-0001-00A-932A-D, Paragraph 2., Concurrent Requirements. **2. BACKGROUND** This service bulletin provides instructions to replace oxygen hoses that supply oxygen to the crew oxygen system. Some low pressure oxygen hoses can potentially be conductive. An anti-kink metallic spring inside the oxygen hose can make contact with the metallic end fittings. If an electrical short circuit causes current to flow through the oxygen hose, heat can generate and cause the hose to melt or burn. Oxygen hose failure could cause a loss of oxygen for the flight crew. In addition, the heat generated could result in smoke and/or fire in the forward electronics equipment bay. An operator in another model Boeing airplane reported a fire near the first officer area which caused extensive damage to the flight deck. A Boeing investigation found that the low pressure flexible hoses in the pressurized flight crew oxygen system can potentially be conductive because of the anti-kink metallic spring inside the hose. This service bulletin will replace potentially conductive oxygen hoses with non-conductive oxygen hoses in the crew oxygen system. The replacement will prevent electrical current from passing through the oxygen hose anti-kink spring which can cause the oxygen hose to melt or burn. Boeing Service Related Problem (SRP) 787-SRP-35-0050 is related to this service bulletin.This table is provided to operators for planning purposes only.
