The Pentagon has grounded its fleet of F-35 fighter jets, after discovering a cracked engine blade in one plane.
The problem was discovered during what the Pentagon called a routine inspection at Edwards Air Force Base, California, of an F-35A, the Air Force version of the sleek new plane. The Navy and the Marine Corps are buying other versions of the F-35, which is intended to replace older fighters like the Air Force F-16 and the Navy F/A-18.
All versions a total of 51 planes were grounded Friday pending a more in-depth evaluation of the problem discovered at Edwards. None of the planes have been fielded for combat operations; all are undergoing testing.
In a brief written statement Friday, the Pentagon said it was too early to know the full impact of the newly discovered problem. A watchdog group, the Project on Government Oversight, said the grounding was not likely to mean a significant delay in the effort to field the aircraft.
