F-35 Fix Could Begin Installation Before End of Year

Engine manufacturer Pratt & Whitney believes it could begin retrofit fixes by November for the engine issue that caused an F-35A to catch fire this summer.
The fire was caused when part of the engine of the F-35A known as AF-27 overheated following a test flight, with two sections rubbing together at a much higher temperature than the engine was designed for. That led to a series of “microcracks,” that spread through the engine and eventually led to part of the engine piercing the plane’s fuel tank.
There are three other engines in the fleet that showed signs of damage from a similar problem.
