F-35 fleet grounded over fuel line fears

- By Ben Riley-smith in Washington and Dominic Nicholls DEFENCE CORRESPOND­ENT

Britain was forced to ground all 16 of its new F-35 fighter jets yesterday after the US government discovered that a faulty fuel tube caused the crash of one of its jets last month. Checks were being carried out to see whether the British F-35s, the most advanced fighter jet ever created, have the same tubes. The US government yesterday announced flights of the jet would be paused as a precaution, prompting Britain and other military allies, including Israel, to follow suit.

BRITAIN was forced to ground all 16 of its new F-35 fighter jets yesterday after the US government discovered that a faulty fuel tube caused a crash last month.

Checks were being carried out to see whether the F-35s, the most advanced fighter jet ever created, have the same tubes as those in the plane which went down.

The US government yesterday announced flights of the jet would be paused as a precaution, prompting Britain and other military allies such as Israel to follow suit.

It is an embarrassi­ng developmen­t for the F-35 programme, the largest and most expensive weapons project of its type in the world.

The planes are designed to be the next generation of fighter jets, capable of carrying bombs and missiles but also rigged up with cyber warfare capabiliti­es – seen as a critical function for 21st -century battlefiel­ds.

The programme is being run out of the United States and a total of 3,000 jets are set to be created ultimately, with many being sold overseas.

Britain has committed to buying 138 F-35s and paid for 48, with just 16 completed so far. Nine of these are currently in the UK and seven still in the US.

The new complicati­on emerged after an F-35B Lightning II stealth crashed near Beaufort, South Carolina, last month. The US pilot ejected safely and there were no civilian casualties.

The cause of the crash was a mystery at the time, but it has since emerged that a faulty fuel tube in the engine played a role. America, British and other military officials were yesterday carrying out checks on all F-35s – looking at paperwork and inspecting engines – to see whether the jets used the same type of fuel tube.

A Pentagon official said: “If suspect fuel tubes are installed, the part will be removed and replaced. If known good fuel tubes are already installed, then those aircraft will be returned to flight status. Inspection­s are expected to be completed within the next 24 to 48 hours.”

The official added: “The primary goal following any mishap is the prevention of future incidents. We will take every measure to ensure safe operations while we deliver, sustain and modernise the F-35 for the warfighter and our defence partners.”

A Ministry of Defence spokesman said: “Safety is our paramount concern, therefore the UK has decided to pause some F-35 flying as a precaution­ary measure while we consider the findings of an ongoing inquiry.”

At least one British-owned F-35 was cleared and was back in the air yesterday. The problem has emerged just weeks after F-35 jets landed on HMS Queen Elizabeth, Britain’s new aircraft carrier, for the first time.

Journalist­s were invited on board for the ceremony, which was seen as a show of the UK’S military might. The type of F-35 Britain has purchased is able to hover before touching down.

Gavin Williamson, the Defence Secretary, said at the time: “The largest warship in British history is joining forces with the most advanced fighter jets on the planet.

“This marks a rebirth of our power to strike decisively from the seas anywhere in the world.”
