From: sharam@.cdac.com (Sean Namazi) Message-ID: <airliners.1994.1611@ohare.Chicago.COM> Date: 29 Sep 94 00:15:37 I'd like to know the validity of the reports on the failure of the 777 P&W engine while being certified for ETOPS. Can anyone shed any light on this? This supposedly occured sometime last week. Aviation Daily reported on September 27 that the PW4000 engine suffered a failure during endurance testing last week. The engine (P008 - eighth production engine) was 700 cycles into a 3,000 cycle ground-endurance test series to clear the 777/PW4000 combo for ETOPS (Extended Twin OPerationS). Ed Crow, a P&W senior VP and chief of PW4000 programs is quoted as saying "There was a failure of two variable vane actuator arms" which help control the movement of variable guide vanes in the engine's compressor. There could be "two weeks, at worst a month, delay to our 3,000-cycle ETOPS testing," he said, but noted that it shouldn't affect the overall 777 test or delivery schedule. The Aviation Daily article gives more details about the failure and about the demanding testing that is being undertaken in order to achieve ETOPS.
