So far, the F-35 inspections bode well for the Pentagon.
About halfway through their testing, investigators haven’t discovered any other cracks in F-35 engine blades besides the one that led to the grounding of the entire fleet of Lockheed Martin F-35 Lightning II fighters.
The grounding of the F-35s comes at a sensitive time for the Defense Department, which faces billions of dollars in across-the-board spending cuts, known as sequestration, set to kick in Friday. Already, the cracked blade has led to calls to cancel the world’s most expensive weapons program, rumblings about alternative engines and renewed tension between the Pentagon and its contractors.
Inspectors have completed “nondestructive testing” on the affected engine blade, including X-rays, according to Kyra Hawn, a spokeswoman for the Defense Department’s F-35 Joint Program Office. The next step is “destructive testing,” which requires the engine blade to be opened and examined.
The entire F-35 fleet is undergoing visual and borescope testing, Hawn added.
“Inspection data should be compiled and presented with analysis and recommendations to senior leadership no later than Friday,” she said. “We will likely authorize ground operations in advance of flight operations to allow for pre-flight inspections and engine runs in preparation for flight.”
Meanwhile, United Technologies Corp., which makes the F-35 engine, is assuring its congressional supporters there’s little to fear. “Our recommendation to the Joint Program Office was to keep flying and simply increase inspections while we figured out the root cause,” the company said in a memo distributed this week to members of Congress considered supportive of the F-35 program.
“The JPO decided on a grounding just to be overly safe,” said the memo, which was obtained by POLITICO. “Because of the unusual nature of the crack, our folks believe that this is not a systemic problem, and the F-35 could be back in ground operations in a few days and possibly flying before the end of the week.”
Still, Matthew Bates, a spokesman for the military engines unit of Pratt & Whitney, a subsidiary of United Technologies, said the company now supports the Pentagon’s decision to ground the F-35.
“Based on our preliminary inspection of the engine, our initial assessment was to continue flight-test operations,” he explained. “However, after more detailed discussion and consultation with the Joint Program Office, we came to understand and support the merits of the decision to suspend flight operations until the investigation was complete.”
The suspension was a “precautionary measure” in response to a crack discovered in a low-pressure turbine blade aboard an Air Force model F-35A last week, Hawn said. F-35s have been grounded before over electrical system problems.
Over the past decade, the roughly $400 billion program has been beset by cost overruns and delays. But it enjoys widespread congressional backing and, according to Lockheed, supports hundreds of thousands of jobs across the country.

他们都那么多问题，我们后面也不会少的
建议楼主大致翻译下要点，不然没人看的
当初不该把备用发动机项目取消的
那就赶紧恢复飞行。
这样一条鸡肋，关注的人还真不少。
如果可以重来，美国早就将其弃之千里之外。
