Pratt & Whitney to begin F-35 engine testing this week

|By:, SA News Editor

Pratt & Whitney (NYSE:UTX) will begin testing a design change this week to fix the issue which caused a massive engine failure aboard a Lockheed Martin (NYSE:LMT) F-35 fighter jet in June.

The failure caused the engine to break apart and catch fire, resulting in the grounding of the entire F-35 fleet for several weeks. Flights have recently resumed, although certain restrictions still apply.

Following Friday's temporary suspension on delivery of engines due to questions over titanium origins, Pratt has now sued its titanium supplier A&P Alloys for fraud and breach of contract.
