A380 soll nächste Woche zum Jungfernflug starten

Mi, 20 Apr '05

Toulouse - "Der erste Flug des A380 ist für die Woche ab dem 25. April vorgesehen", teilte Airbus mit und präzisierte damit frühere Aussagen. Der genaue Tag stehe noch nicht fest, hieß es weiter. Das hänge auch vom Wetter ab. Bereits seit vergangener Woche laufen in Toulouse Roll- und Bremsversuche mit dem größten Passagierflugzeug aller Zeiten.

Ursprünglich sollte der Testflug bereits Anfang April stattfinden. Airbus-Chef Noel Forgeard hatte Spekulationen zurückgewiesen, die Verschiebung könnte den Zeitplan für die Erstauslieferung 2006 durcheinander bringen. Bei einem so langfristig angelegten Projekt komme es auf "ein paar Tage oder Wochen" nicht an, sagte der Manager

Die TT62 Alekto fliegt

Do, 23 Feb '05

Gut 2 Jahre arbeitete das Team der High Performance Aircraft GmbH & Co. KG (HPA) auf diesen Termin hin. Nun hatte das Luftfahrtbundesamt die vorläufige Verkehrszulassung erteilt, und bei den benötigten guten Wetterbedingungen war es am 22.02.2005 soweit.

Der Testpilot Gerard Guilaumaud startete zum ersten Mal die TT62 auf der Bahn in Heringsdorf auf Usedom. Mit moderater Geschwindigkeit flog er zunächst in niedrigen Höhen über die Insel.

Jury Blames Textron Lycoming for Airplane Engine Failures

Thu, 17 Feb '05

Orders Company to Pay $96 Million

A jury in Grimes County, Texas has found Textron Lycoming liable for fraud, and ordered the company to pay approximately $96 million to Navasota, Texas-based Interstate Southwest Ltd. The verdict came Tuesday following seven weeks of trial in State District Judge Jerry Sandel's 278th Judicial District Court in Anderson, TX.

The jury's award includes $9,725,650 in actual damages and another $86,394,763 in punitive damages. In addition, the verdict effectively precludes Lycoming from pursuing a $173 million indemnity claim against Interstate, which it had previously filed in a Pennsylvania court.

"This is a total victory for our side," says attorney Marty Rose, who represents Interstate Southwest. "Between the verdict and its impact on the indemnity claim -– we couldn't have hoped for a better result."

The case revolves around a number of small airplane engine failures that occurred when the airplanes' crankshafts broke in flight. Between 2000 and 2002, there were 24 failures and 12 deaths in Cessnas, Pipers and other airplanes with Lycoming aircraft engines. Interstate Southwest supplied Lycoming with the crankshaft forgings for those engines.

Following the failures, Lycoming launched an investigation aimed at determining the cause. Its conclusion was that Interstate Southwest had overheated the forgings, weakening the steel.

But attorneys for Interstate, Rose and Hal Walker, found a different cause. Their experts were able to determine that Lycoming's design for the crankshafts, which dates back to smaller, lower horsepower engines built 40 years ago, was inadequate for the larger, higher horsepower engines that failed. 

They also found that by adding Vanadium to the steel -– something Lycoming decided to do just before the failures began -– the company further limited the amount of stress the crankshafts could withstand. Lycoming had added Vanadium to make the steel harder and reduce the number of machining operations, ultimately saving the company money. 

Ultimately, jurors agreed with lawyers for Interstate, and found that even Lycoming's investigation of the crankshaft failures was fraudulent.

"The jurors found the combination of poor design and Vanadium pushed these crankshafts beyond their limits," says Hal Walker. "That's why these planes crashed, and not, as Lycoming claimed, because Interstate overheated the forgings."
