The Pentagon has requested unscheduled emergency repairs to jet engines on all F-35 aircraft, both those in US service and those sold to partner nations, Defense News reported March 2.
Pratt & Whitney, owned by Raytheon Technologies, must upgrade the engines to prevent their resonant vibration, which has already become a brand-new F-35B crash in Fort Worth, as a result of which the pilot had to eject.
Following this incident, aircraft manufacturer Lockheed Martin stopped accepting new F-35s until the cause of the crash was rectified. On February 2, Lockheed confirmed to Defense News that it had not yet resumed flights or accepted new F-35s.
As the article says, upgrade even the entire F-35 fleet “cheap and hassle free” but all F-35 engines will have the same configuration. Presumably, aircraft modernization work can be completed in four to eight hours.
More than 890 F-35s worldwide will be affected by the update, according to Lockheed Martin sales statistics.
