The F-35 Lighting II is not the only aircraft facing problems. The F-35B used by the Marine Corps are grounded after a fuel line detached and caused a propulsion system leak that led to an aborted take-off.
The F-35B is the most complicated design in the Pentagon’s F-35 program. It is capable of short take-offs and vertical landings. The test flights of the fifth generation jet plane conducted by the Marine Corps were immediately suspended after the incident.
The Pentagon’s investigation revealed a quality discrepancy resulting in a crimped line in the plane’s fueldraulic system was at fault. The propulsion system was made by Pratt & Whitney unit of the United Technologies Corp. (UTX).
Initially, the faulty fuel lines were planned to be sent to Europe, but in order to save time and money, it will be scanned in the U.S. The components will undergo a CT scan in order to detect the flaws.
Replacement fuel lines are already available and Marine Corps test flying are likely to resume soon.
