AD/B767/125 Oxygen Masks 10/2000

Applicability: Model 767 series aeroplanes with line numbers 1 through 682 inclusive.

Requirement: 1. Unless previously accomplished, perform a general visual inspection to determine the vendor of all oxygen masks in the passenger cabin in accordance with Boeing Service Bulletin (SB) 767-35-0033, including Appendix A, dated 10 September 1998. If the oxygen mask is not manufactured by Puritan-Bennett, no further action is required by this Directive for that mask.

Note 1: For the purposes of this Directive, a general visual inspection is defined as: "A visual examination of an interior or exterior area, installation, or assembly to detect obvious damage, failure, or irregularity. This level of inspection is made under normally available lighting conditions such as daylight, hangar lighting, flashlight, or drop-light, and may require removal or opening of access panels or doors. Stands, ladders, or platforms may be required to gain proximity to the area being checked."

2. If the oxygen mask is manufactured by Puritan-Bennett, or if the manufacturer of the mask cannot be identified, perform a general visual inspection to determine the manufacturing date of the oxygen mask, in accordance with the applicable service bulletin. For each oxygen mask manufactured by Puritan-Bennett, or an unidentified manufacturer, if the mask was manufactured between May 1986 and July 1998 inclusive or if the manufacturing date cannot be determined accomplish either of the following:

Replace the lanyards on the masks with new lanyards in accordance with SB 767-35-0033, including Appendix A.

b. Replace the existing oxygen mask with a new mask that was manufactured by Puritan-Bennett before May 1986 or after July 1998, or by another vendor, and that has the same Boeing part number, or that is approved by the United States Federal Aviation Administration (FAA) for installation as an alternative to the Puritan-Bennett mask.

3. No person shall install an oxygen mask manufactured by Puritan-Bennett between May 1986 and July 1998 inclusive, on any aeroplane, unless the lanyard has been replaced with a new lanyard in accordance with Requirement 2. B of this Directive.
