  • PW1100G Geared Turbo Fan

    Pratt and Whitney have found themselves in a strange situation. Their order book is brimming with orders for the PW1100G ( Geared Turbo Fan) but the engine used in the Airbus 320/321 Neo is being removed in record numbers for repair. In total 1200 engines will need repairs. The problem is a number of small cracks appearing in the powdered metal used in the engines High Pressure Turbine disks that were manufactured between 2015 and 2021.

    At the moment Pratt and Whitney are producing more engines than are being removed to bring AOG (Aircraft On Ground) rates down. The defect is having an effect on multiple airlines in the busy summer season. Pratt and Whitney have increased engine production to minimize the downtime of existing customers by having engines available. Despite this, approximately 10% of the GTF fleet is parked awaiting engines. Indian airline Go First recently cited the engine as the primary reason they filed for bankruptcy.

    There are also problems with the PW1500G series engine installed in the Airbus 220. The reliability of the engine is well below the target that Pratt and Whitney expect. Some PW1524G engines in the A220-300 are being removed at less than a thousand landings instead of the forecast 5260 landings. There is an Engine Airworthiness Directive for inspection of the engine fan due to inflight shutdowns and the failure of fan blades.

    Now, in my experience there are always teething troubles with new designed engines that only appear after operational real world experience. The manufacturers do their best to cover all the bases to achieve certification from the regulator but, they can’t anticipate all the environmental affects that the engines will experience.

  • There is Hope for Diamond Owners

    The following article must be good news for Thielert powered Diamond aircraft owners after months of indecision.
    Diamond certifies Austro AE 300 turbo-diesel

    Diamond Aircraft has received European type certification for its turbo-diesel Austro AE 300 engine, a development the company says “secures its future.”

    Diamond had been scrambling to develop an alternative to the Thielert Centurion 2.0 turbo-diesel engine after Thielert filed for bankruptcy in April last year. The Centurion powers more than 400 DA40 piston singles and more than 500 DA42 twins. Diamond has not ruled out offering a Thielert option on future aircraft assuming the company recovers after a pending sale.

    “The complete program developed into one that was significantly more complex than originally anticipated,” says Diamond CEO Christian Dries of the certification effort, which ultimately took 42 months to complete at a cost of  €48 million. Dries says there are already 27 DA42 NG aircraft powered by AE 300 engines on the production line and type certificate for the aircraft is expected “imminently”.

    Dries says Diamond next will certify the engine as forward-fit for the DA40 and DA50, and will develop an AE 300-powered version of the DA42 multi-purpose platform. The company will also offer a retrofit version for its existing Thielert diesel-powered aircraft.

    So if all goes well those diesel engined dreams of avoiding all the problems with traditional engines may be alive again.Austro Engine

  • Zoom Airlines Financial Troubles

    News today about Zoom Airlines which operates flights between Canada and the United Kingdom (UK) has run into financial problems. An aircraft was taken back from Zoom by the owner who leased the aircraft to them. This was after the Calgary Airport refused to refuel them as the bill owed to the airport authority was in excess of $400,000. A little while later the airport authority in Glasgow, Scotland refused to allow a Zoom aircraft to leave because the Civil Aviation Authority in UK had outstanding bills from the European Air Traffic Control agency (Eurocontrol) that had to be paid. 

    Zoom Airlines has now filed for creditor protection in the UK and Canada as they have a financial plan in place to sort their cash flow out which 95% completed. If the protection is granted by the courts the airline will continue to operate and the passengers will not be left holding worthless ticket.

    Many of the airlines in the world have been in Protection from the courts in the last few years and have managed to survive. This is now part of the business plan of airlines in the world of rising fuel prices and competition for passengers. We can only hope the airline survives and all the jobs with it are not lost.

     

    Update
    Zoom Airlines has now stopped operations. The airline management say that the actions of the creditors prevented them from continuing to fly and therefore the decision has been made to stop all further operations. The company apologises to all the passengers and more than 600 employees who are now out of work.
