One of the F-35Bs involved in flight trials with the British aircraft carrier HMS Queen Elizabeth was one of the jets that required a repair to its fuel pipe, the First Sea Lord has revealed.
This month the F-35 Joint Program Office (JPO) issued an enterprise-wide inspection of a fuel tube within the engine on all F-35 aircraft after a US F-35B crashed in South Carolina.
At the time the Ministry of Defence announced five of the UK's 16 F-35B fighter jets required a replacement fuel tube after engine inspections.
Admiral Sir Philip Jones spoke to Forces News during an event to mark the state visit of King Willem-Alexander and Queen Máxima on Wednesday.
The First Sea Lord told Forces News one of two jets conducting trials with the UK's aircraft carrier needed a repair to fix the fault.
Admiral Sir Philip Jones said: "We’ve been flying two F-35s from the Integrated Test Force in Patuxent River Air Base in America over the course of the last five weeks.
"They form part of a global force of F-35s, mostly US still, but some in UK hands and some in other nations’ hands.
“All of them were tested to see whether they had the engine variant that required that fuel pipe replacement.
"Two fly from HMS Queen Elizabeth, one did and one didn’t, so we kept flying with one all the time - the other one was quickly repaired."
