The U.S. military on Friday grounded the F-35 fighter jet due to a crack in an engine component that was discovered during a routine inspection in California.
The Pentagon said in a statement that it was too early to assess the impact on the fleet of jets designed for use by the Navy, Air Force and Marines.
The nearly $400 billion Joint Strike Fighter is the Pentagon's most expensive weapons system. It is currently being tested.
The program has been beset by cost overruns and various technical problems during development.
Currently, there 51 planes in the F-35 fleet.

The White House has agreed to turn over to the Senate Intelligence Committee additional e-mails and intelligence reports related to the lethal attack on the U.S. mission in Benghazi, Libya, according to a congressional source.
The source said some of the materials have already been received by the panel and others "will be provided shortly."
Republican senators have threatened to hold up the nomination of John Brennan as CIA director until they receive e-mails exchanged between the White House and the spy agency concerning public talking points about the deadly attack last September 11.
U.N. Ambassador Susan Rice relied on those talking points to explain the Obama administration's version of events several days after the armed assault. Her televised comments ignited an election-year controversy, fueled by Republicans, over whether the administration was being truthful about the nature of the attack.
