Schon air buy two used C-172 for their training operations
there aricraft are already been used by its older company. Schon air also hav got their new registration from CAA Pakistan which are AP-BJG and AP-BJF as schon previously have two C-172 as AP-BHT and AP-BDV. so now schon air have 4 C-172 in their fleet for their training operation.



Two new F-35s set to join flight-test fleet

Two more Lockheed Martin F-35s are set to join the flight-test fleet as programme officials work to recover from a setback on 9 March.

Carrier variant flight-test aircraft CF-2 is scheduled in early April to become the eleventh member of the active flight test fleet, Lockheed says.

The final addition, CF-3, is in the company's "final finishes" position on the assembly line in Fort Worth, Texas, but should achieve first flight before June.

With the original AA-1 prototype inducted into live-fire testing last year, the arrival of CF-2 and CF-3 means the test fleet will finally reach full strength in a few months.

The new F-35s will join a fleet that is just overcoming an electrical power shutdown during a test flight of the AF-4 test aircraft on 9 March.

That incident forced the programme to ground all 10 flying aircraft for seven days. Seven of the 10 flight-test aircraft were cleared to return to flight on 16 March. The last three F-35s in flight test resumed flying on 25 March after being grounded for nearly 16 days.

An internal investigation revealed the cause of the power failure to be a maintenance procedure. A small amount of "extra" oil was allowed after maintenance service to remain inside the generator, according to the F-35 joint programme office.

"Under some conditions, the extra oil that is churning inside a narrow air gap," the office says.

This causes the temperature within the generator to increase. On the 9 March flight, both generators over-heated, forcing the F-35's second back-up - the integrated power-pack - to take over. The F-35 needs electricity to move its flight controls.

The problem affected the alternate engine starter/generator, which is installed on AF-4, BF-5, CF-1 and all low-rate initial production aircraft. The other seven flight-test aircraft operate with a different engine starter/generator, and were not affected by the grounding.

Despite the flight-test disruption, programme officials do not expect the overall schedule to change. "Flight-test schedules are built with a margin for precautionary safety stand-downs," the programme office says.

IndiGo selects P&W to power up to 150 A320neos

In a major coup for Pratt & Whitney's geared turbofan, A320neo launch customer, Indian low cost carrier IndiGo, is to announce it has selected the PW1100G to power up to 150 of the updated Airbus narrowbodies, say those familiar with the deal. While the official announcement for 300 engines is expected as early as today, the win by the East Hartford-based engine maker comes on the heels of a hard-fought campaign to secure the right to provide 300 engines and associated service contracts to power what Airbus touts as the "largest single firm order" for large jets in commercial aviation history. IndiGo signed an 11 January memorandum of understanding with Airbus for up to 180 A320 aircraft, including 150 of the re-engined A320neos, making it the European airframer's launch customer for the new variant due for entry into service in 2016. Missing from the initial MoU was an engine selection, kicking off a fierce behind-the-scenes competition between the CFM International Leap-X and Pratt & Whitney PW1100G as both vied for the massive contract.



The selection represents the second win for Pratt & Whitney on the re-engined jet, having been chosen by International Lease Finance Corporation (ILFC) to power at least 60 of its 100 A320neo and A321neo aircraft.

The selection as launch customer also establishes the PW1100G as the lead powerplant to fly first for Airbus's certification campaign.

Airbus says the new engine option for the A320 will reduce fuel burn up to 15%, compared to today's A320, a savings of over 1,510,000 litres (400,000gal) of Jet A and 3.600t CO2 per year.

The PW1524G, the first model of the P&W's PW1000G engine family, is currently in ground testing at two facilities in Manitoba, Canada and West Palm Beach, Florida as it progresses toward its first assignment to power the 110 to 125-seat Bombardier CSeries CS100 aircraft on its 2012 first flight and subsequent 2013 entry into service.

The PW1000G has also been selected to power the 70 to 90-seat Mitsubishi Regional Jet MRJ70 and MRJ90, as well as the 150-seat Irkut MS-21.
