Airworthiness Directive 2020-18-16
one-timeAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. This AD was prompted by the FAA's analysis of the Model 767 fuel system reviews conducted by the manufacturer. This AD requires modifying the fuel quantity indicating system (FQIS) to prevent development of an ignition source inside the center fuel tank due to electrical fault conditions. This AD also provides optional actions for cargo airplanes. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2020-18-16 applies to
Excludes airplanes on which the center auxiliary tank consists only of the dry-bay space between side-of-body rib 0 and rib 3 (not part of the fuel tank), and airplanes equipped with an FAA-approved FRM (14 CFR 25.981(b)/26.33(c)(1)) or IMM (14 CFR 25.981(c)/26.33(c)(2)).
Whether AD 2020-18-16 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.
