Engines Should Be Pulled From Service Pending Checks, Board
Says
As a result of its ongoing investigation of an incident
involving a Pratt & Whitney PW2037 engine experiencing an
uncontained failure, the National Transportation Safety Board
issued an urgent recommendation Thursday to the Federal Aviation
Administration to require all Pratt & Whitney PW2037 engines be
removed from service for inspection of the second stage turbine
hubs when they have accumulated significantly fewer hours (10,880)
and/or cycles (4,392) than the incident engine.
