Pratt & Whitney halted F-35 engine delivery over titanium origin

|By:, SA News Editor

United Technologies' (NYSE:UTX) Pratt & Whitney unit says it suspended delivery of engines for the F-35 jet, the Pentagon’s costliest weapons program, over concern that a supplier may have provided “suspect” titanium.

UTX says delivery was halted in May after an in-house inspection and testing process raised questions about the origin of the titanium; UTX replaced all suspect engine parts in its inventory for failing to meet specifications, but determined the titanium in 147 F-35 engines already delivered did not pose a flight safety risk.

The Pratt & Whitney engine accounts for $68.4B of the $398.6B projected cost of the F-35 being built by Lockheed Martin (NYSE:LMT).
