Ca semble se confirmer pour le A330 Cathay !
Les 2 moteurs fonctionnaient mal ! Emergency déclarée aussi !
Vu ailleurs qu'il se sont posés à 230 Knts, des raisons pour faire de la fumée au freinage !
PB d'alim de fuel, probable, contaminé peut être, ou des Fohe RR qui ont refait leur coup favori (La boule de neige balladeuse)??
J'ajoute que les calculateurs du A330 se sont peut être fourvoyés dans l'interprétation des problèmes : Irrégularités sur les 2 moteurs, qu'est ce qu'on fait, si la puissance baisse (Manque ou eau dans le kéro) quant on l'augmente ! Brrr!
Le bain salé n'est pas passé loin !
A suivre !

More facts are now coming in from Cathay Pacific's live media conference in Hong Kong. Essentially Cathay Pacific reaffirmed that the aircraft did not lose any engine power after reaching cruise altitude. Both engines did produced asymmetrical thrust while in-flight but other engine parameters remained normal and as a result the flight continued to Hong Kong as normal. Arriving close to Hong Kong, 20 minutes before arrival, engine 2 surged and it was shut down by the crew before being restarted and kept at idle. Emergency was declared and the aircraft continued for an approach into Hong Kong with engine 1 still running but there was trouble in reducing the thrust on engine 1. During the approach, engine 1 was producing thrust at 70% N1 and engine 2 was at idle. The aircraft finally touched town on the touch down zone at around 230 knots and full braking was done to stop the plane. Once the plane was stopped, the captain had a word with the fire service who confirmed there was fire and smoke coming from the tyres and a decision was made to evacuate all the passengers. In summary, the flight crews exhibited superior airmanship for being successful in getting the aircraft safely on ground in this situation.

HONG KONG—Both engines on the Cathay Pacific Airways Ltd. jet that made an emergency landing in Hong Kong on Tuesday malfunctioned during the approach to the airport, according to Hong Kong's civil aviation department, in a rare development that could have had catastrophic results.
After the pilots of the Airbus A330-300 aircraft shut off one malfunctioning engine, the aircraft's remaining engine suffered technical problems and wasn't producing the thrust needed to properly operate the plane, Director-General of Civil Aviation Norman Lo said Wednesday.
"The engine was stuck at a certain thrust level and the pilots weren't able to adjust it with their power settings," Mr. Lo said in an interview with Radio Television Hong Kong. The crew had trouble controlling the aircraft's speed, and as a result, the plane touched down at nearly double the normal speed of landing, he said.
"Based on the preliminary data we've seen, the emergency situation was very intense and the crew responded appropriately...there was just 20 minutes to react," said Mr. Lo, adding the cause of the incident is still under investigation.
While modern twin-engine jets are designed to function normally with only one engine operating, a malfunction in both engines could lead to a complete loss of thrust. Such malfunctions are extremely rare, aviation experts have said.
