Airworthiness Directive 2016-07-05
one-timeAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-8 series airplanes. This AD requires an inspection to determine if all oxygen components in the passenger oxygen system are installed, installation of new o-rings, and corrective actions if necessary. This AD was prompted by a report that oxygen tube couplings in the passenger oxygen system could be missing or incorrectly installed. We are issuing this AD to detect and correct oxygen leaks from oxygen tube couplings in the passenger oxygen system, which could result in depletion of emergency oxygen at a faster rate than expected, reduce the passengers' and crews' protection from hypoxia at elevated cabin altitudes, and increase the risk of a fire.
Which aircraft AD 2016-07-05 applies to
Applies to airplanes as identified in Boeing Special Attention Service Bulletin 747-35-2132, dated June 8, 2015.
Whether AD 2016-07-05 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
