Pentagon temporarily grounds new F-35 jets after crash - 11 Oct 18

Washington (CNN)The Defense Department has temporarily grounded all of its 245 F-35 fighter jets for inspection of a potentially faulty engine part in the wake of last month's crash in South Carolina.

Initial data from the ongoing investigation into the September 28 crash indicates a fuel tube may have been faulty. In response, all US military F-35s will be inspected as well as F-35s operated by US allies. "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," the Defense Department said in a statement. Inspections are expected to be completed within the next two days, the statement said, and a defense official told CNN some aircraft have already been returned to flight status.

The initial assessment is the faulty tube may be on older models of the aircraft, but all are being inspected.

The first US combat mission conducted by an F-35 happened last month when a Marine Corps jet launched off the amphibious warship USS Essex struck targets in Afghanistan. In May, Israel announced it had conducted the first combat missions ever using the F-35 but offered few details.

Other nations that have signed contracts to join the F-35 program include the UK, Italy, the Netherlands, Turkey, Canada, Australia, Denmark and Norway, according to the Pentagon. The Air Force has 156 F-35 aircraft in inventory; the Marine Corps has 61 and the Navy has 28.

The F-35 stealth jet has been called the most expensive weapons system in history, and its development was beset by multiple delays before it was deemed combat ready. The jet, which has reduced capability to be seen by adversary radars, has been a favorite of President Donald Trump, who has lauded the F-35 several times for being "invisible."

My error. It does say fuel tubes.

The fuel tube problem wasn't as extensive,and 80% of the fleet is operational.

F-35 Testing May Slow Two Months Due To Fuel Tube Crash
More than 80 percent of operational F-35s have returned to flight operations but the fuel tube problems may delay testing another two months.

Although more than 80 percent of the F-35 fleet is back in the air after the program’s first crash, I understand from a source intimately familiar with the testing regime that initial operational testing (IOTE) is likely to be delayed up to two months by the fuel tube problem afflicting the fleet.

I contacted the Joint Program Office and spokesman Joe DellaVedova said today:

“November 2018 is still the target start date for formal operational testing, pending completion of the remaining readiness actions. Impacts from a mandatory fuel system inspection are being assessed.” (Emphasis added)

Underside of the F-35B as it does a vertical landing back on the USS Essex after the F-35’s first-ever combat strike .

Now, two months (or less) is not a huge amount of time, but it comes on top of years of delays to the program. By the way, this would be the second two-month delay to IOTE in 2018, so that would be four months in one year, which isn’t insignificant. (We wouldn’t be surprised if POGO comments on this as proof of more “problems” with the F-35).

Here’s what the F-35 program said in its official statement Monday — after I inquired:

“After completing inspections, more than 80 percent of operational F-35s have been cleared and returned to flight operations. All U.S. services and international partners have resumed flying with their cleared aircraft.”

The rest of the JPO statement, however, indicates that the other 20 percent of the fleet may not get into the air for an unspecified period:

“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.” (Again, emphasis ours).

Not no mention of IOTE. Now, DellaVedova’s statement today says the target remains next month, but it also admits the effects of the discovery of the faulty fuel tube aboard the F-35B that crashed Sept. 28 near Beaufort, S.C. are still “being assessed.” So, we’ll see.

Ça explique, mais ça n'excuse pas.
