Applicability: All Boeing 767 series aeroplanes as detailed in the Requirement document.

9/90

Requirement: Re-route the aft equipment/lavatory/galley ventilation fan wire bundles along the frame assembly at Stn 1540 IAW Boeing ASB 767-21A0074.

Note: FAA AD 90-08-13 also refers.

Compliance: Prior to 6 September 1991.

Background: This AD is prompted by a report of charred insulation blankets aft of station 1540 which resulted from arcing and burning of damaged wire bundles. This condition, if not corrected, could result in a fire behind the aft cargo compartment wall.

Compliance with this AD is required in order to minimise the possibility of inadvertent damage to the wire bundles.
