Напоследък наистина лош късмет за Airbus:
Seven injured in Airbus A330 test flight depressurisation
Seven occupants of an Air Mauritius Airbus A330-200 aircraft were taken to hospital after a depressurisation incident yesterday (21 November).
The twin-jet, the first of two A330s ordered by the carrier last year was performing a customer-acceptance flight from Toulouse, the final step in the process before an aircraft is delivered. It had been due to be formally received by Air Mauritius in the next few days.
Ten people were on board the aircraft: three Airbus personnel, six from Air Mauritius and one representative of a supplier. Two pilots and an observer were in the cockpit at the time, while the others were moving around the cabin.
"While in the cruise there was a sudden decompression," says a spokeswoman for Airbus. "When it happened it was so sudden that there was no time for [those in the cabin] to grab oxygen masks. Some became dizzy and unconscious."
There is no firm information on the altitude of the A330 at the time. Standard procedures following decompression include performing a swift descent to an altitude of around 10,000ft where atmospheric oxygen density is sufficiently high.
Seven people were taken to hospital as a precaution although all but one have since been released. The Airbus spokeswoman describes the occurrence as a "minor incident" and says none of the occupants suffered serious injuries.

Iberia indicates Quito overrun A340 will be repaired
Iberia is leaning towards repairing the Airbus A340-600 badly damaged in a runway overrun at Quito in Ecuador two weeks ago, although the carrier has yet to reach a final decision.
The 18-month old jet, owned by the carrier, suffered damage to its left-hand engines and undercarriage during the 9 November accident.
A spokeswoman for Iberia says: “We think it will be repaired. But this is still to be decided.”
Investigators, engineers and assessors have been examining the jet in order to decide how to remove it from the accident site, at the northern end of Quito Airport’s runway 17/35.

Toulouse A340 throttles not idled until 2s before wall collision
Flight-recorder information from the Airbus A340-600 involved in the Toulouse ground-test accident last week shows that the aircraft’s engines were not retarded to idle until two seconds before the jet struck its test-pen wall.
The aircraft, which had been performing an engine and brake test, was travelling at around 30kt (55km/h) at the time of impact.
French investigators have determined that the A340-600, which was undergoing pre-delivery checks, was being held at standstill with the parking brake on and all four Rolls-Royce Trent 500 powerplants running with a relatively high engine pressure ratio of 1.24-1.26.
Wheel chocks were not inserted under the aircraft at the time of the 15 November accident.
In an information telex to operators Airbus states that high-thrust engine ground runs are normally only performed on one powerplant at a time, with the corresponding engine on the opposite wing running at limited thrust to counterbalance. It adds that wheel chocks should be installed during such tests.
While the parking brake is set, the A340’s alternate brake system provides the brake pressure. This pressure was normal during the Toulouse A340’s engine run.
Investigation agency Bureau d’Enquetes et d’Analyses states that the aircraft, for as-yet undetermined reasons, began to move forward after the engines had been running for about 3min.
The Airbus communication says the crew applied brake-pedal input within 1-2s of the initial movement and switched off the parking brake; the regular braking system’s pressure rose to its normal level.
But Airbus adds that all four engine thrust levers were only retarded to their ‘idle’ setting about 2s before the aircraft collided with the wall. By that point the aircraft had been in motion for around 11s.
“There is no evidence of any aircraft system or engine malfunction,” says Airbus vice-president for flight safety Yannick Malinge. “Airbus reminds all operators to strictly adhere to [aircraft maintenance manual] procedures when performing engine ground runs.”
Investigations are still continuing into the accident which destroyed the aircraft and injured several of the nine personnel on board. The jet had been scheduled for delivery to Etihad Airways on 21 November.
