Airworthiness Directive 96-08-05
one-timeAirworthiness Directives; Boeing Model 747-400 Series Airplanes Powered by General Electric CF6-80C2 or Pratt & Whitney PW4000 Series Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-400 series airplanes, that requires modification of the engine fuel feed system. This amendment is prompted by reports indicating that the coupling nut on the fuel tube on the outboard strut (engine position 1) fractured. The actions specified by this AD are intended to prevent such fracturing of the coupling nut, which could result in release of fuel onto the engine cowling and a subsequent fire.
Which aircraft AD 96-08-05 applies to
Extracted text begins at the standard 'preceding applicability provision' boilerplate; the AD's actual model/serial list precedes this excerpt and was not captured by extraction. Actions target strut fuel tubes/couplings at engine positions 1 and 4 on Boeing 747-400 series airplanes. Compliance option (a)(1) covers airplanes identified in Boeing Alert SB 747-28A2185 Rev 1 (Sept 21, 1995); option (a)(2) covers 747-400 airplanes with variable numbers RT641 through RT650 inclusive per Boeing SB 747-28-2146 (Aug 13, 1992).
Whether AD 96-08-05 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.
