All US F-35s grounded worldwide

All US F-35s grounded worldwide

The Pentagon announced Thursday it is grounding its entire fleet of F-35s, just days after the first crash of an F-35B led investigators to suspect there is a widespread problem with the advanced fighter’s fuel tubes.
“The U.S. Services and international partners have temporarily suspended F-35 flight operations while the enterprise conducts a fleet-wide inspection of a fuel tube within the engine on all F-35 aircraft,” the F-35 Joint Program Office announced in a statement Thursday morning.
“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 office said the grounding “is driven from initial data 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.”
In the Sept. 28 crash in South Carolina near the Marine Corps Air Station Beaufort, the pilot safely ejected from the aircraft, which belonged to 2nd Marine Aircraft Wing, Marine Fighter Attack Training Squadron 501, known as the “Warlords.”

While the F-35′s U.S-based Joint Program Office had indicated that the grounding included aircraft purchased by foreign militaries, the British military signaled Monday that its entire fleet is not grounded.
Contrary to reports, all F-35 jets have not been grounded. We have paused some F-35 flying as a precautionary measure while we consider the findings of an ongoing enquiry. Flight trials from @HMSQnlz continue and the programme remains on schedule #F35 @thef35

The F-35 Joint Program Office has said safety is a top priority.
“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 modernize the F-35 for the warfighter and our defense partners.”
The U.S. grounding comes after the Pentagon announced that a Marine Corps F-35B conducted the platform’s first-ever combat mission on Sept. 27. The Marine Corps' aircraft launched from the amphibious warship Essex, striking targets in Afghanistan.
In April, a Marine Corps F-35B out the Marine Corps air station at Cherry Point, North Carolina, was forced to make an emergency landing when the aircraft fuel light came on.
The grounding news also comes two days after Defense News reported that Secretary of Defense Jim Mattis has ordered the military services to get readiness rates on four planes, including the F-35, up above 80 percent by next September.

According to data for fiscal year 2017, the most recent available, the Air Force’s F-35A models had around a 55 percent readiness rate, well below that target.
Although the Marine Corps is the first U.S. service to fly its joint strike fighters in combat, the aircraft has been used by the Israeli air force to strike targets. In May, Israel Defense Forces officials confirmed that the country’s F-35 “Adir” fighters had seen combat in two airstrikes somewhere in the Middle East.
The Marine Corps declared the F-35B operational in 2015, becoming the first service to integrate the joint strike fighter into its fleet. The Air Force followed by declaring initial operational capability for the F-35A conventional variant in 2016, while the Navy plans to declare initial operational capability for the F-35C carrier variant in February 2019.
The F-35 joint strike fighter is the most expensive program in the Pentagon’s history.
Currently, the U.S. military has purchased 245 aircraft from Lockheed Martin. The Air Force has 156, the Marine Corps has 61 and the Navy has 28, according to data provided by the joint program office.

The U.S. Air Force, Navy and Marine Corps plan to buy a total of 2,456 F-35s, at an estimated cost of $325 billion. In total, the aircraft program is projected to cost about $1 trillion to develop, produce, field and sustain over its lifetime, according to the Government Accountability Office.
The F-35B is the short takeoff, vertical landing variant of the aircraft, which allows the pilot to hover and land vertically like a helicopter — a necessity for the Marines, which typically operate from amphibious ships with smaller decks than aircraft carriers.
Because the problem is related to a fleetwide engine issue, rather than just in the F-35B models, it appears unlikely that the problem is unrelated to the short-takeoff and vertical-landing capabilities of the Marine’s design.
The issue as described by the JPO indicates the issue is believed to come from a subcontractor who supplied the fuel tubes for engine manufacturer Pratt & Whitney.
A spokesman for the F-35s manufacturer, Lockheed Martin, said Thursday morning that industry partners were working with the F-35's Joint Program Office to investigate the problems.

"We are actively partnering with the Pentagon’s F-35 Joint Program Office, our global customers and Pratt & Whitney to support the resolution of this issue and limit disruption to the fleet,” said Friedman, Michael, the spokesman for Lockheed.
The U.S. Government Accountability Office has projected a total lifetime cost of $1 trillion for the program. F-35s have already been delivered to the United Kingdom, Italy, Israel, Netherlands, Turkey, Australia, Japan, South Korea and Norway.

Mohon maaf kalau tritnya berantakan atau pun repost, soalnya hanya copas dari sumbernya & moga2 ini masalah bisa segera diselesaikan & pilot yg nerbanginnya pun bisa lebih aman menjalankan tugas.

Beri apresiasi terhadap thread ini Gan!
USS Essex (LHD-2) sekarang lagi di Teluk Persia, gotong 1 skuadron F-35B. Kalau sewaktu-waktu "dibutuhkan" siap diterbangkan. Begitu juga dengan IAF, jika dibutuhkan, mereka siap tempur emoticon-army
Walopun sampe kejadian accident, tapi bisa dibilang klo dari hasil investigasinya kan cuman fuel tube yg bisa dgn cepat diganti, klo dr artikelnya sih infonya 48jam harusnya sudah kelar.
Balasan post bodanno

hanya separuhnya yang pakai faulty tube. setelah di cek batch mana yang kena maka separuh yang grounded akan langsung clear to fly kembali.

tapi separuhnya nunggu parts, unlikely bakal secepat 48 jam.

update squadron f_35 dong. mana yang dah pesiaran di laut ?

Sepertinya F 35B yg paling sering kena masalah diantara varian lainnya.
imho kemungkinan sih bakal cepet operasional lg, krn mereka dah ada ALIS alis
All US F-35s grounded worldwide

Royal Navy starts F-35B rolling vertical landing trials

Sbnrnya AL AS tanpa F35 itu sudah superior di kawasan teluk.....jd g khawatir lah klo utk smntr di grounded smbl evaluasi ap yg g beres
AS klo soal tranparansi alutsista nya memang terbuka....klo ada problem y ngaku....klo ud siap y ngasi tau....
WASHINGTON — After a fuel tube problem sidelined all operational F-35 aircraft last week, more than 80 percent of jets have been cleared to return to flight, the F-35 joint program office stated Monday.

In a Oct. 15 statement, the JPO confirmed that the U.S. services and international partners have completed inspections of their F-35 inventories for faulty fuel tubes. The aircraft that are not impacted by the bad tubes — which are a component in Pratt & Whitney’s F135 engine — are back in flying status.

“The F-35 Joint Program Office continues to work closely with the military services to prioritize fuel tube replacements using the current spares inventory,” the JPO said. “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.”

Last week, all U.S. and international F-35s were momentarily grounded to allow for an enterprise-wide fuel tube inspection. The review began as a result of an investigation into a Sept. 28 Marine Corps’ F-35B crash near Marine Corps Air Station Beaufort in South Carolina — the first F-35 crash in the jet’s history.

It is still unclear exactly how the defective fuel tubes impact the jet’s performance or how serious a safety threat they pose during flight operations. Joe DellaVedova, a spokesman for the JPO, declined to discuss the specific problems that led the program office to call for a fleetwide inspection, saying that details could not be released until the Marine Corps completes its accident investigation.

Also still up in the air is whether the Pentagon or Pratt & Whitney will be stuck paying the tab for retrofitting the fleet.

Spokesmen from the U.S. Air Force, Marine Corps and Navy declined to lay out exactly how many of their aircraft had been impacted by the faulty fuel tubes. However, as Lockheed Martin delivered its 300th F-35 in June, 20 percent of the operational F-35 fleet can be estimated to be about 60 aircraft across the U.S. and international operators.

The JPO called the fuel tube problem an “isolated incident” that would not impact F-35 deliveries. A total of 91 F-35s are planned to be delivered to the U.S. military and foreign customers this year.

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

The problem with the defective fuel tubes is the latest in a string of recent supply chain issues that have plagued F-35 prime contractor Lockheed Martin and engine manufacturer Pratt & Whitney, and comes as Defense Secretary Jim Mattis sent a memo directing the Air Force, Marine Corps and Navy to boost the F-35′s mission capable rate to 80 percent.

The Pentagon halted F-35 deliveries in March amid disagreements over whether the department or Lockheed should foot the bill for retrofitting part of the fleet that had not received corrosion-preventing primer in certain fastener holes. Deliveries resumed in May once the parties hammered out an agreement — although it was never revealed to the public exactly how the expenses would be paid off.

In 2016, certain F-35As were grounded after it was found that coolant lines inside the jets' fuel tanks were rimmed with faulty insulation, which was prone to disintegrating.
Ini yang gua suka, kalo ada problem selalu terbuka alias ada transparansi.
