A quasi due mesi dall'incidente ..... un ulteriore allentamento delle restrizioni ..... ma solo per i velivoli impiegati nei collaudi ..... mentre l'Esercito riesce ad ottenere la sua fettina di torta .....
The F-35 Joint Strike Fighter test fleet will be able to fly six hours between engine inspections for weapon test and refueling missions, as restrictions on the fifth-generation fighter continue to ease.
Previously, the entire F-35 fleet was limited to three hours of flight time before an engine inspection was required as an investigation continues into a fire that heavily damaged an F-35A model on June 23.

Ecco quanto riporta questa mattina il "Daily Report" dell'AFA .....
http://www.airforcemag.com/DRArchive/Pa ... Eased.aspx
The F-35 program office said investigators are still working to pinpoint the exact cause of the fire at Eglin, although they have tentatively said a fan blade rotor was excessively rubbing against the engine casing.
Program officials said fixes under consideration range from an engine redesign to establishing a “break-in” period for each motor that would allow for the gradual contraction, expansion, and strain on the engine to prevent premature structural cracking.
However, a final solution awaits a definitive “root cause” for the fire.
Mica tanto incoraggiante ..... :mrgreen:

Non recentissimo ..... ma interessante .....
The F-35 joint strike fighter may well come to rule the skies of the future, but for decades to come it will need to work with existing “fourth-generation” fleets.
Finding ways to make that work is an early topic being discussed at this year’s Farnborough International Airshow.
BAE, a major partner on both the F-35 and Eurofighter Typhoon programs, is undergoing tests to find ways to link the training systems for the two planes together in order to determine best tactics for operations, according to a company spokesman.

Dicono di aver (quasi) capito qual'è il problema .....

Dal sito dell' AFA .....
Therein Lies the F135 Rub..... (John A. Tirpak 9/4/2014)

Investigators think they understand why an F135 engine problem caused an F-35 strike fighter to burn in June, slowing the test and training effort, program manager Lt. Gen. Christopher Bogdan said Wednesday.
Speaking at the COMDEF 2014 conference in Washington, D.C., Bogdan said the natural “flex” of the mishap engine under high-G conditions caused fan blades to “rub” and “dig too deep” in the rubber-like seal around the powerplant.
From 138 possible causes, “we’ve narrowed it down to four” and the root cause could be some combination of them all, Bogdan said.
Steps to address the issue are underway, including a “burn in” technique requiring two sorties per engine that could prevent the problem on other jets.
Bogdan expects a permanent fix in late October, but “I need 21 test airplanes” back to full capability “by the end of the month or else there will” be delays to the flight test program.
The engine problem has created a 30-45 day “headwind,” but Bogdan believes he can make up some of that.
Pratt & Whitney, maker of the strike fighter’s F135 engine, has been “very, very good” about solving the issue, Bogdan said.
“They’ve put their A-team on this” and agreed—before the likely root causes were identified—to bear the cost of retrofitting the 156 F135 engines now extant.
Pentagon acquisition, technology, and logistics chief Frank Kendall told reporters at the conference earlier in the day he expects a fix soon and at “a relatively minor cost.”
Bogdan said the mishap jet may be used for “battle damage repair” training.
The problem has nothing to do with a separate titanium supplier issue causing Pratt to replace parts in other F135s, Bogdan said.

Qualche dettaglio in più .....
The microcracks in the third stage of the integrally bladed rotor that caused a catastrophic F135 engine fire in an F-35A on June 23 began forming three weeks earlier when a pilot conducted a fairly benign maneuver with a unique combination of yaw, roll and g stresses, according to the F-35’s program executive officer.
Quanto mai singolare, per non dire involontariamente comica, questa dichiarazione del generale Bogdan .....
"Pratt and Whitney’s reaction to this problem from my opinion has been very, very good," Bogdan said.
"From a technical standpoint, they have put their A team on this.
From a business standpoint, they realize this is a problem they need to solve."

The company, a division of United Technologies, has also agreed to share the cost of any future engine design changes with the government, said US Air Force (USAF) Lieutenant General Christopher Bogdan, the Pentagon's programme manager for the effort.

P&W F135 ..... si sta cercando la soluzione ..... e intanto affiorano nuove (si può dire imbarazzanti ?) informazioni .....
The long-delayed operational debut for the Lockheed Martin F-35 Joint Strike Fighter is at risk of further slippage due to a safety-critical problem with its Pratt & Whitney F135 engine for which no single root cause has yet been identified.
Senior leaders initially dismissed the fire that damaged F-35 AF-27 at Eglin AFB, Florida, on June 23 as a “one-off incident,” as U.S. Marine Corps commandant Gen. James Amos called it in mid-July.
However, Aviation Week has learned that at least five engines have been removed from F-35s after showing signs of premature wear.
-----
Five F135 engines have been pulled from F-35s after failing an inspection regime that was instituted after the June 23 fire.
One of the failed engines was removed from F-35 CF-9 (the ninth production F-35C), an aircraft with fewer than 70 flight hours, according to a retired military officer and JSF program veteran.

Dal 'Daily Report' dell'AFA ..... una serie di dichiarazioni rilasciate dal sempre ottimista (e..... come potrebbe fare a non esserlo?) generale Cristopher Bogdan in occasione dell'annuale 'Air & Space Conference' dell'associazione .....
Bogdan: F-35A Schedule Low Risk .....
(John A. Tirpak 9/16/2014)

Achieving operational capability with the Air Force's version of the F-35 strike fighter in August 2016 is "low risk," said Lt. Gen. Christopher Bogdan, F-35 program executive officer, at AFA's Air & Space Conference in National Harbor, Md., on Monday.​
Bogdan said "there is margin" in the program to accommodate delays even with the aircraft's recent engine problems and perpetually challenging software issues.
In software, the program has consumed four to five months of its six-month cushion, but Bogdan said he is not yet concerned, because the problems are being worked.
As for other well-publicized F-35 technical issues—with the pilot's helmet, the carrier landing hook, a fuel-dump problem, and ability to absorb lightning strikes—they are "in the rearview mirror," he said.
Each was a "big risk two years ago; now, not so much," he said.
Technical solutions to all of those issues are in hand and several are already nearly through flight test, said Bogdan.
He said he loses little sleep over technical issues, because "there are no problems we can't solve on this program."
He has slightly more concern about "programmatics and affordability," and the latter is tied almost entirely to keeping the buy numbers intact.
Fixing the F135 .....
(John A. Tirpak 9/16/2014)

Engineers are "very, very close" to conclusively determining the root causes of why an F135 engine started a fire in an F-35 strike fighter in June, and a decision on various fixes will likely be final by the end of October, said F-35 Program Executive Officer Lt. Gen Christopher Bogdan on Monday.
He told an audience at AFA's Air & Space Conference outside of Washington, D.C., that the fix is proceeding along several lines, and some combination of "six options" will resolve the situation.
The options revolve around fixing the problem in new-build F135 engines—by potentially changing material that engine mounts rub against—and retrofitting some 150 extant motors, by gradually letting them "burn in," by performing certain maneuvers in the aircraft, said Bogdan.
Pratt & Whitney, F135 maker, will pay for the fixes, he noted.
In an interview with Air Force Magazine after his speech, Bogdan said "I don't think it will be a massive cost," and will be driven more by touch labor than by replacing parts.
P&W military engines chief Bennett Croswell, in a separate briefing for the press on Monday, noted that "we will validate the root causes [of the incident] by the end of the month," and that of all F135 engines, only three have been found with a similar problem brewing.
The company is on a "path to a solution … in six months," he said.
He also pointed out that the F135 is performing very well otherwise, "way above the maturity curve" of any previous fighter engine.
F-35 Incentives Plan .....
(John A. Tirpak 9/16/2014)

​F-35 contractors have put up some $170 million to invest in cost-reducing projects on the strike fighter under a plan that gives them high incentive to make the projects succeed, and quickly, said Lt. Gen. Christopher Bogdan, F-35 program executive officer, in a Sept. 15 interview.
He told Air Force Magazine that the contractors can get all their money back by sharing the savings with the services.
"The sooner these things pay off, the sooner they get their money back," and after that, the faster they will generate higher profits, said Bogdan.
"So it is 'win-win,' for us and for them," he said.
If the initiatives don't work out, the contractors don't get reimbursed, "so they have lots of incentive to make it work quicker," said Bogdan.
He added that "the beauty of it" for the program is that improvements negotiated in a given lot are "booked in that lot," and the government gets the savings right away, and from there on, whether the improvement works out or not.
It Was the Monster Mods .....
(John A. Tirpak 9/16/2014)

​A looming issue for the F-35 program is the process of reconfiguring already constructed aircraft to the final configuration needed to achieve initial operating capability, said F-35 Program Executive Officer Lt. Gen. Christopher Bogdan.
"The mod program is a monster … and you can quote me," he told Air Force Magazine in a Sept. 15 interview.
The challenge is that parts suppliers are "stressed" because they're producing parts in three configurations: one version for new production; one version to sustain aircraft already bought, and another version to support modification kits.
More suppliers have been brought in, said Bogdan, and that has "done a decent job" in reducing parts shortfalls.
But to produce the 10 airplanes the Marine Corps needs in a common configuration to achieve initial operating capability by next year "requires 58 modifications" to each jet, broken down into several groups, some of which have to be performed at depot, and others that can be accomplished at their operating base, he said.
It's a "full time job" for one of the F-35 deputies to manage the modification effort, said Bogdan.
E, a proposito della citata e prossima 'Initial Operational Capability (IOC)' degli F-35B dei Marines, ecco quanto scrive Jane's' .....
Marine Fighter Attack Squadron 121 at MCAS Yuma has begun training to IOC-specific standards.
The USMC plans to become the first of the three US military services to declare F-35 IOC in July 2015.

The F-35 joint strike fighter will likely be protected regardless of whether the Pentagon is operating under limits imposed by the Budget Control Act in fiscal 2016, the program’s top official said Monday.
“I have faith in the Department of Defense leadership that when they tell me and the services that if sequestration comes we’re going to do everything we can to minimize the impact on the program, because that is what we need to do,” Lt. Gen. Christopher Bogdan, the head of the F-35 joint program office, said.

Lorraine Martin, who leads Lockheed’s F-35 programme, outlined on 16 September a handful of the several hundred potential manufacturing and materials changes that seek to cut $10 million per year from the aircraft’s unit cost up to 2019.
The company has promised that by then, the F-35A will cost $80 million or less.

Lockheed Martin has delivered the latest iteration of the system that brings fifth-generation logistics and maintenance capability to the F-35 Lightning II fleet.
The autonomic logistics information system (ALIS) version 2.0 is being tested and validated for installation at all F-35 squadron locations, beginning in 2015.
An initial version of ALIS is currently operating at nine locations, and has been used to manage more than 12,000 sorties to date.

Procedura standard ..... e conseguenti, nonché imbarazzanti, ritardi nella diffusione delle informazioni ..... ovvero ..... tutto il mondo è preda della burocrazia ..... :laughing5:
When the F-35A exploded June 23 on the runway, it took about 10 days before the Pentagon had worked out how to communicate to the public, to the Navy, Marines and Air Force and to its international partners what had happened, was happening and would happen.
Today, Air Force Lt. Gen. Christopher Bogdan said that his office was doing a “complete rewrite” of its mishap planning process.
The problem was that the pilot reported to Air Education Training Command (AETC), so the command followed standard procedure and posted armed guards around the plane and did not share information with the Joint Program Office, with the Navy or Marines — let alone the rest of the Air Force or the international partners.
That made no one happy.

Il punto sulla situazione .....
The F-35 is a complicated program.

That’s not really news, I know.
Technologically, the jet may be the most advanced piece of hardware the military has ever played with, requiring millions of lines of code and all sorts of gadgets spread over three physically different models.
Economically, it’s a Frankenstein’s monster of a program, with a trio of Pentagon services, eight partner nations who each have an economic hand in the program, and three foreign sales customers.

Keeping track of everything that’s going on is a challenge in the best of times.
Luckily for you, we here at Intercepts are ready to help.

Un nuovo balletto di cifre ..... con conseguente strascico di polemiche .....
The F-35′s long-term costs may “not be affordable” and appear to be substantially higher than those of the existing combat aircraft fleets that the Joint Strike Fighter will replace, the Government Acocuntability Office says in a draft report.
“The annual F-35 operating and support costs are estimated to be considerably higher than the combined annual costs of several legacy aircraft,” the draft says.
This issue is likely to be a topic of debate at the JSF Executive Steering Board meetings to begin Thursday in Oslo, Norway.
The nine countries that invested in the F-35′s development will hold bilateral meetings on Wednesday.
Then they gather in the shadow of the Norwegian parliament as a group the next day.
The estimated gap between the F-35 sustainment costs and those of the F/A-18, F-15, F-16 and the Harrier fleets as measured in 2010 is impressive, about $8.8 billion, an increase of 79 percent.
That estimate comes from the Pentagon’s authoritative Cost Assessment and Program Evaluation (CAPE) office, the GAO draft report says.
The draft says that costs for the legacy fleet were about $11 billion a year in 2010.
Based on CAPE’s estimate, the F-35′s annual costs will be $19.9 billion in 2012 dollars.

Ovvero ..... non passa giorno che non emerga una qualche notizia sconfortante relativa al tormentato programma del 'wonderfighter' .....

L'obiettivo fissato dalla mozione è quello "di massimizzare i ritorni economici, occupazionali e tecnologici". L'assemblea ha approvato anche le altre mozioni della maggioranza, tutte con il parere favorevole dell'esecutivo (da Sc la richiesta al governo di "aggiornare" il programma in relazione alle esigenze di bilancio) e quella presentata da Fi (anche in questo caso parere favorevole dal governo). Bocciate la mozione del Movimento 5 stelle che chiedeva la totale cancellazione della commessa dei caccia americani F35 di Lockheed Martin, programma al quale partecipa anche Finmeccanica, e quella della Lega Nord che chiedeva l'eventuale sostituzione della commessa degli F35 con altri caccia meno evoluti F22.

A parte gli scherzi ..... e tornando in argomento ..... tutto ciò mi da l'impressione che si tratti della consueta 'aria fritta' ..... in quanto a me sembra che il punto sia soltanto questo .....
"La discussione delle mozioni è del tutto intempestiva e demagogica - tuona Ferdinando Adornato (Udc) -. Prima di tutto perché il governo si è già impegnato a una revisione in base al Libro Bianco della Difesa, e quindi le valutazioni andranno fatte in quella fase".

C'è la possibilità che, alla luce dei ritardi accumulati dal programma e dalla ventilata possibilità di ulteriori tagli all'acquisizione dei velivoli (F-35A e tutti i B) destinati all' AM (mentre il numero dei B destinati alla MM ben difficilmente verrebbe toccato), potrebbe accadere questo .....
Italy also aims to continue operations for at least “10 or 15 years”, according to chief of air force operations Lt Gen Maurizio Lodovisi.

..... in attesa di futuri 'tempi migliori' (se mai ci saranno) che possano consentire l'acquisto di qualche esemplare di F-35A in più per l' AM .....
Si tratta comunque, al momento attuale, soltanto di mie elucubrazioni ..... Immagine
