Compliance

Required actions
Within 750 flight hours or 15 months after the effective date of this AD, whichever occurs first: Replace lanyards having part numbers (P/N) B431564-503 and -505 for all passenger oxygen dispensing units, with lanyards having P/N B431564-507, in accordance with the Accomplishment Instructions of Bombardier Service Bulletin 700-1A11-35-009, Revision 02, dated May 28, 2013.
Unsafe condition
This AD was prompted by a report that certain lanyards for the passenger oxygen masks are longer than the specified length, possibly leading to inactive oxygen masks in an emergency. We are issuing this AD to detect and correct lanyards of incorrect length, which might not activate the flow of oxygen in an emergency, resulting in injury to passengers.
Affected ADs
None.
