US Air Force 419th Fighter Wing have flown their 10,000th sortie with the F-35A.
The flight occurred at Hill AFB say the US Air Force in a release. The base is slated to be home to three F-35 fighter squadrons with a total of 78 aircraft by the end of 2019.
The active duty 388th FW and Air Force Reserve 419th FW will fly and maintain the jet in what the USAF are calling a “Total Force partnership”, which capitalises on the strength of both components.
Recently, after completing inspections, more than 80 percent of operational F-35 jets have been cleared and returned to flight operations with the rest to follow, say Lockheed Martin.
In a statement, the firm say that all US services and international partners have resumed flying with their cleared aircraft.
“The F-35 Joint Program Office continues to work closely with the military services to prioritize fuel tube replacements using the current spares inventory. Pratt & Whitney is rapidly procuring more parts to minimize the overall repair timeline for the remaining jets.
Current inventory will restore about half of the impacted jets to flight operations, and the remaining aircraft are expected to be cleared for flight over the coming weeks.
The issue is not expected to impact F-35 deliveries and the program remains on track to meet its target of 91 aircraft for the year.”
Earlier in the month, the F-35 Joint Program Office issued an enterprise-wide inspection of a fuel tube within the engine on all F-35 aircraft resulting in a temporary grounding so inspections could take place. The jets currently undergoing trials on HMS Queen Elizabeth were amongst the first to return to flight.
5 of the UK’s 16 F35s were found to have fuel tubes needing replaced, it is understood that those five aircraft remain grounded pending replacement of the tubes.
Lockheed say that if an engine had a suspect fuel tube installed, the part was to be removed and replaced. If the engine had a known good fuel tube installed, then the aircraft could return to flight status.
“More than 1500 suppliers are on the F-35 program and this is an isolated incident which is quickly being addressed and fixed. Safety is our primary goal, and we will continue to take every measure to ensure safe operations while we execute our mission.
The action to perform the inspection resulted from the ongoing investigation of the F-35B that crashed in the vicinity of Beaufort, South Carolina on 28 September. The aircraft mishap board is continuing its work and the U.S. Marine Corps will provide additional information when it becomes available.”
The primary goal following any mishap is the prevention of future incidents, the issue now appears to have been resolved.
