Airworthiness Directive 2001-16-07
one-timeAirworthiness Directives; Boeing Model 747-400 and 767 Series Airplanes Equipped With General Electric CF6-80C2 Series Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-400 and 767 series airplanes, that requires modification of the core cowl assemblies of the engines. This action is necessary to prevent failure of the core cowl latches during an engine fire, and consequent in-flight separation of an engine core cowl and its strut fire barrier from the airplane. This action is intended to address the identified unsafe condition.
Which aircraft AD 2001-16-07 applies to
Applies to Model 747-400 series and 767 series airplanes; requires modification of left- and right-hand engine core cowl assemblies per Boeing SB 747-71-2285 (747-400) or 767-71-0088 (767 series) to prevent core cowl latch failure during an engine fire, and prohibits installing aluminum core cowl assembly P/N 224-2301-513 (LH) or 224-2302-539 (RH).
Whether AD 2001-16-07 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.
