Unsafe Condition

The in-line flow indicators of the passenger oxygen masks may fracture and separate, inhibiting oxygen flow to the masks and potentially exposing passengers and cabin attendants to hypoxia following a depressurization event.

AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Inspect the oxygen masks in the passenger service units and flight attendant/lavatory oxygen boxes to determine the manufacturer and manufacture date. Perform a general visual inspection of the flow indicator to check the color of the flow direction mark, the word 'flow', and the presence of the letter 'W' on the ID label. Replace discrepant oxygen masks with ones not manufactured by B/E Aerospace between January 1, 2002, and March 1, 2006, or with modified masks having an improved flow indicator.
