F-35 soars again  (Source: Lockheed)
GE Aviation sees hopes of second engine for F-35 dashed

The F-35 Lightning II is one of the most expensive weapons program ever and has been plagued with cost overruns and delays since it launched. New details on the generator failure that caused an emergency landing and the subsequent grounding of the F-35 fleet have been unveiled.

Defense News reports that the generator failure that affected test aircraft AF-4 has been determined to be the result of an improper maintenance technique that goes along with a new generator layout in some of the newer F-35 fighters. Once the problem was traced to the new generator layout in newer aircraft, the F-35s using the older generator layout were cleared to resume flight operations.

The earlier aircraft that resumed flight operations included three F-35As and four F-35Bs. Defense News reports that the maintenance procedure has now been revised and that the full fleet of F-35s are now back to operation.  The aircraft with the older generator layout resumed flights on March 14. The cause of the generator failure in the test aircraft was traced back to an excess of oil inside the generator.

The excess oil circulation inside the generator after maintenance caused the generator to overheat and fail. Lockheed claims that the loss of flight time has not impacted the test flight schedule. The F-35 program is still ahead of its flight schedule for the month.

The F-35's have taken back to the air, but AMD Online reports that the second power plant for the F-35 has officially been killed. We reported in February that the House was set to vote on the bill to kill the second engine.

The stop work order was announced last Thursday. GE Aviation in Ohio was developing the second engine.

The second engine hasn't been "killed"

GE and RR are going to self-fund it for a bit.

As for everyone asking for it (2nd engine) to be cancelled... they could do with remembering the lessons of history.

How did the GE F110 fare compared to the PW TF30s in the F-14?

How did the GE F110 fare compared to the PW F100 in the F-16?

Hmmm....

You the mean the TF30 that was the first afterburning turbofan that didn't have FADEC and was meant for a different airplane.

Lemme ask you this: would you buy new 911 turbo and then ask ferrari to built a back up car because the 1978 911 turbo would spin and crash if it wasn't driven correctly.

Why would I talk to Ferrari about a back up car to a 911 turbo?

So. Completely irrelevant.

Pertinent. But not the sole source of all the TF30's problems.

Irrelevant. If you think the intake was not designed for the engine your off your rocker.
