USAF Chief: Pratt Close To Developing F-35 Engine Fix

Engine manufacturer Pratt & Whitney is close to performing tests on a potential design change for its F135 engine following a June incident that led to the devastation of an F-35 Joint Strike Fighter.
The June 23 fire was caused by “excessive” rubbing of a fan blade inside the engine of an F-35A model as it prepared to take off for a test flight at Eglin Air Force Base.
Inspectors are still investigating the root cause of the incident to determine if it was a manufacturing or design flaw, but in the meantime the company has begun design on a potential solution.
