The U.S. Military has grounded all f-35 fighter jets after a crack in an engine compartment was found during a routine inspection.
This comes just one day after Marine Corps Air Station-Yuma celebrated the first operational flight in Yuma Thursday.
The problem was discovered during what the Pentagon called a routine inspection at Edwards Air Force Base, Calif., of an Air Force version of the F-35. Other versions of the F-35 are flown by the Navy and the Marine Corps including at MCAS-Yuma.
The F-35 is the Pentagon's most expensive weapons program at a total estimated cost of nearly $400 billion.
The suspension of flight operations will remain in effect until an investigation of the problem's root cause is determined.
The Pentagon said the engine in which the problem was discovered is being shipped to a Pratt & Whitney facility in Connecticut for more thorough evaluation.
MCAS-Yuma is hoping to get an update on the F-35 later next week.
