ASB 747-35A2035, Revision 1.

           Inspections and follow-on actions accomplished prior to the effective date of this Directive in accordance with Boeing SB 747-35-2035, dated 7 January 1983, are acceptable for compliance with corresponding actions of this Directive.

           Note 2: FAA AD 2001-24-29 Amdt 39-12546 refers.

 AD/B747/265 (continued)

 Compliance: For Requirement 1 - Before 16 July 2003.

           For Requirement 2 - Before further flight following the Requirement 1 inspection. This Airworthiness Directive becomes effective on 21 February 2002.
           Background:  This Directive requires a one-time inspection for chafing between the hose for the passenger oxygen system (hereinafter called the "oxygen hose'') and adjacent electrical wire bundles at certain passenger service units and, if necessary, corrective actions. The Directive also requires rerouting or reorienting the oxygen hose to ensure sufficient clearance between the hose and electrical wire bundles.

           These actions are necessary to prevent chafing between the oxygen hose and adjacent electrical wire bundles, which could result in arcing of a chafed electrical wire bundle and consequent burn-through of the oxygen hose. If this occurs when the oxygen system is pressurized, such arcing could represent a potential ignition source in an oxygen-enriched environment.
