Interim Fix For A400M Propeller Gear Box Still In Works
Apr 26, 2016Amy Svitak | Aerospace Daily & Defense Report
PARIS — GE Aviation’s Avio Aero is working near- and long-term solutions to address a balky component on the EuroProp International (EPI) TP400-D6 engine, four of which power the new AirbusA400M tactical airlifter.
The component, a propeller gear box (PGB) designed and produced by Avio Aero of Italy, revealed multiple technical issues earlier this year, though only one of the problems persists, says Philippe Petitcolin, CEO of French aerospace supplier Safran, whose Snecma motors division is a major partner in the EPI consortium.
Airbus says the PGB issue involves the cracking of a component known as the input pinion plug, which in some cases can result in the release of small metallic particles into the oil system, where they are found by a magnetic chip detector.
As a result, the European Aviation Safety Agency (EASA) has issued an Airworthiness Directive mandating immediate on-wing inspection, followed by replacement if evidence of damage is found, or else return-to-service and continuing inspections.
Airbus says while this problem does not constitute a safety issue, it did cause an inflight engine shutdown on an A400M in service with the U.K.
“As a partner we are fully supporting Avio in solving the problem as soon as possible,” Petitcolin told investors during a first-quarter earnings call April 26. “We are applying with EPI a two-step approach, with an interim fix which is going to be ready in the next few weeks.”
A more definitive solution will take “months,” he said.
In the meantime, Airbus has delivered three A400M airlifters this year, all to the U.K. Although the company is still targeting a total of 20 deliveries this year, that figure is being negotiated with A400M contracting authority Occar, which manages the procurement of the aircraft for partner nations Belgium, the U.K., France, Germany, Luxembourg, Malaysia and Spain.
During the investor call, Petitcolin also said Safran is closing in on the completion of a joint venture combining its space activities with those of Airbus Defense and Space to form Airbus Safran Launchers (ASL). The deal has drawn the scrutiny of the European Commission, the executive arm of the European Union, which has questioned ASL’s planned purchase of stock ownership in the Arianespace launch consortium, a roughly 34% stake that is currently held by French space agency CNES.
“We are making good progress. We are expecting the signing very soon,” he said of the ASL merger, adding that the company has already answered the European Commission’s first round of questions, and more recently responded to a series of follow-ups. “We expect the joint venture to be fully operational on July 1.”
Software Cut Off Fuel Supply In Stricken A400M

FRANKFURT and LONDON—The crash of anAirbus A400M airlifter that killed four people on May 9 may have been caused by new software that cut off the engine-fuel supply, industry sources have said.
Four company personnel, including both test pilots, died when the aircraft—which had been destined for the Turkish air force—crashed on agricultural land north of Seville San Pablo Airport shortly after takeoff on its first flight.
Two flight-test engineers were pulled from the wreckage and remain in the hospital.
Sources have told Aviation Week that aircraft MSN23, destined for Turkey, featured new software that would trim the fuel tanks, allowing the aircraft to fly certain military maneuvers.
The sources state that the exact sequence of events is not yet clear, nor is it clear whether all four engines failed at some point. Some reports have suggested three engines failed. There also seems to have been a trimming issue leading to strong banking that was not recoverable.
The fuel supply was re-established, but not quickly enough for recovery to safe flight.
Details about the software have emerged as Airbus Defense and Space requested all operators of its A400M airlifter conduct checks on electronic control units (ECUs) fitted to the TP400 turboprop engines on the aircraft.
Airbus alerted the five air arms operating the transport aircraft to perform one-time specific checks of the ECUs on each of the aircraft’s engines before the next flight. The company also has introduced additional detailed checks, to be carried out in the event of subsequent engine or ECU replacement.
The company said these checks were necessary to “avoid potential risks in any future flights,” and adds that the results have been shared with the official investigation team.
In a statement, the company said the alert had resulted from its internal analysis and was issued as “part of the continued airworthiness activities, independently from the ongoing official investigation [into the accident].”
Airbus restarted development flight-testing of the A400M on May 12, but the company still is subject to the withdrawal of the Spanish defense ministry’s permit to test-fly production aircraft.
The majority of A400M customers have halted flights with the aircraft until more details about the cause of the accident emerge. Only France, which has six aircraft, is continuing flight operations. One of the U.K.’s aircraft is reportedly stuck in New Mexico awaiting the lifting of the British defense ministry’s self-imposed flight pause.

Президент концерна Airbus Том Эндерс признал наличие «огромных ошибок» в ходе проектирования военно-транспортного самолета А400М.
«Мы недооценили проблемы с двигателем, и мы попали в ловушку», – цитирует Эндерса блог bmpdЦентра анализа стратегий и технологий со ссылкой на французский журнал Air&Cosmos.

Он также добавил, что «в этом заключаются две огромных ошибки, за которые мы действительно должны заплатить».

Airbus takes fresh €1bn charge against A400M
- 27 JULY, 2016

- LONDON
Airbus’s continued difficulties with producing and delivering the A400M tactical transport have led it to announce a fresh charge of just over €1 billion ($1.1 billion) against the programme.
“Industrial efficiency and the step-wise introduction of the A400M’s military functionalities are still lagging behind schedule and remain challenging,” says Airbus Group chief executive Tom Enders.
Five A400Ms were delivered during the first six months of this year, including MSN33 to the French air force – the service’s ninth example, and the programme’s first to be capable of conducting tactical duties.
Airbus chief financial officer Harald Wilhelm notes that almost as many A400Ms have been handed over so far during July. This follows the receipt of European Aviation Safety Agency certification for an interim fix to an engine propeller gearbox (PGB) issue that has severely restricted operations since early this year.

Expected to be available to customers from September, this fix will increase the period between inspections of affected parts from 100 flight hours to at least 650h.
“We have got a good co-operation spirit between us and the engine partners, including GE/Avio, to provide the necessary fixes to make the propeller gearbox really the robust key element of the [Europrop International TP400-D6] engine that it should be,” Enders says.
Enders confirms that the programme’s customers will be entitled to compensation as a result of delays, but says the “negotiation process has not even started” via Europe’s OCCAR defence procurement body. “Customers are dealing with us in a very constructive spirit,” he says, adding that they “want to get this aircraft as soon as possible".
“We are increasingly able to turn out capable aircraft now that the immediate PGB crisis, I think, has been mitigated by finding this temporary fix,” he says.
In a half-year results statement issued on 27 July, Airbus warns: “The potential impacts on the [future] financial statements could be significant.” However, Enders says he does not “expect additional charges that come close to the order of magnitude that we are booking right now.”
The development of tactical capabilities will continue over the next two to three years, but Enders says the effort is “very much in the court of the engine-makers, to outfit this aircraft with a very robust, long-living engine and propeller gearbox.”
Airbus also identifies “technical issues related to the aluminium alloy used for some parts within the aircraft”, and “recurring cost convergence issues and finally some delays, escalation and cost overruns in the development programme” as also affecting the A400M. It also has made an “updated assumption of export orders during the launch contract phase”.
Despite the challenges, Enders says Airbus Defence & Space is now “making good progress”, and that the Atlas is demonstrating “impressive performance” with the air forces of France, Germany, Malaysia, Turkey and the UK. France’s recently-accepted MSN33 is “an aircraft that you can send into harm’s way – not just a better freighter”, he says.
