Requirement: 1. Inspect the PBE units in accordance with the Accomplishment Instructions of Puritan Bennett Aero Systems Service Bulletin 119003-35-1 dated 15 February 1993 to confirm that a yellow label is attached to the red rip tag.

2. Remove from service units without the yellow label.

Note: FAA AD 93-24-16 Amdt 39-8765 refers.

Compliance: 1. Prior to 1 March 1996.

2. Immediately following the inspection.

Background: Some PBE units have been found to have deteriorated neck seals.

This condition could reduce the protection afforded the crewmember if the PBE unit was used while locating and/or extinguishing an inflight fire.

Compliance with this Directive provides a method of early detection of PBE units with deteriorated neck seals and decreases the likelihood of crewmembers being affected by smoke.
