  • PW4000 AD Just Released
    Posted by Lee Ann Tegtmeier 4:25 PM on Nov 23, 2010

    FAA just released an airworthiness directive (2010-24-09) for Pratt & Whitney PW4000 because of a "report of a repaired No. 3 bearing oil tube that caused an engine inflight shutdown, seven reports of repaired No. 3 bearing oil pressure tubes found cracked that led to unscheduled engine removals, and one report of a test cell event from a repaired tube that cracked."

    The AD requires operators to inspect this No. 3 bearing oil pressure tube one time to ensure no cracks exist, and of course, if damage exists, to repair it.

    The AD, which affects the 94", 100" and 112" engines, takes effect Dec. 28.
