    F-35s Grounded After Power Package Fails

    By DAVE MAJUMDAR
    Published: 3 Aug 2011

    All 20 U.S. F-35 Lightning IIs have been grounded following a failure of the aircraft's integrated power package (IPP).The IPP issue occurred in one of the U.S. Air Force's conventional takeoff and landing F-35As.

    The incident took place at about 8:30 a.m. Aug. 2 at Edwards Air Force Base, Calif., during a ground maintenance run of aircraft AF-4, the fourth conventional takeoff and landing version of the triservice Joint Strike Fighter. Following the failure of the IPP - which combines the functions performed by an auxiliary power unit, emergency power system and environmental controls - the crew shut down the aircraft as per standard operating procedures, according to a press release by the JSF program office. There were no injuries.

    Government and contractor teams are reviewing the incident to find out what caused the IPP to fail. The program office suspended flight operations as "the prudent action to take at this time until the F-35 engineering, technical and system safety teams fully understand the cause of the incident," according to the statement.

    This is the second time the F-35 has been grounded this year due to electrical problems. In March, the F-35 fleet was briefly grounded after the same aircraft experienced a dual generator failure that was traced to faulty maintenance procedures.

    The Navy's F-35C was also grounded for six days in June due to a software problem with the wing-fold mechanism that might have caused the flight control surfaces to freeze in flight. The aircraft returned to flight June 23.

    Don't be drowned by the irony of the situation. Their remaining 4.5+ generations air superiority and multi role fighters can still decimate France's fighters several times over...

    Possibly bad maintenance is to blame, or new parts that did not suit the APU. Who knows?

    If it is a small issue then fine, but if it is a big issue then expect more delays and cost escalations.

    F-22 pilots losing qualification as Raptors remain grounded

    Air Force F-22 pilots are losing their training edge as the Raptor fleet enters its fourth month of a grounding, the Air Force Times reported.

    They can't figure out what is wrong with the F-22, then they don't figure what is wrong with the F-35 mean no 5th gen capability.
