Boeing has begun a five-year fatigue test on the wing of a U.S. Air Force B-1 bomber to validate the predicted life of the bomber fleet, currently forecasted to be 2050. The test also will reveal potential areas of concern for which Boeing and the Air Force can develop maintenance and repair plans.

"This comprehensive testing is a proactive way for Boeing to meet its mission of keeping the B-1 bomber fleet ready and viable," said Rick Greenwell, Boeing B-1 program director.

Boeing and the Air Force also plan to fatigue-test a B-1 fuselage at Boeing Tukwila beginning in November 2013.
