the pilots of The problem aircraft A220 are allowed to enter in the flight not full boost. The manufacturer Airbus, Canada, and the canadian aviation safety authority have issued the appropriate instructions.
This has been released on Monday by the Federal office for civil aviation (Foca). The new Airbus aircraft, the Swiss have suffered margins in the last few months, several Engine. In August, about a machine lost on the way to London via France engine parts and had to be in Paris between land.
in mid-October, the Swiss groundete the entire fleet of C-Series, such as the A220 is also known. After an inspection of the 29 aircraft were back in operation. The engines were in perfect condition, informed the Swiss at the time.
Now, the investigation has revealed first clues as to the cause of the problems. In the plot statement, the pilots are instructed to type at a height of 29 000 feet to a maximum of 94 percent thrust. The automatic thrust control must be switched off.

get flights in high altitude at full thrust could lead to a failure of the engine, and damage to the aircraft, i.e. in the so-called airworthiness Directive. The thrust limitation is recorded in the new flight manual of the A220.

in Addition, the aircraft in weather conditions in which icing of the aircraft is possible, not over 35’000 feet altitude to be flown. According to the manufacturer, the Turning on of the deicing system can lead to this height, the Overheating of the engine and set off the fire alarm, which leads to an abort of the flight.
About the underlying cause for the engine problems no information is provided. The investigations continued, according to the airworthiness Directive. A safe flight is ensured the operation, said Swiss Chef Thomas Klühr in an Interview with the “look”. But it would be a better feeling when you know the exact cause already.

The airworthiness Directive had been issued on the basis of the experience of the Swiss, it was said to the Foca on request. It was a further precautionary measure which had been taken in connection with the engine problems.
The Swiss has introduced two weeks ago, a flight height limit, as the airline announced on request. Since then, the A220 no longer fly up to 29’000 feet. The airworthiness Directive has therefore no impact on the flight of Swiss. On the basis of which findings the airline, the measures taken, not shared with you.
The Swiss was the first customer of the C-Series, flies for 2016 with machines of this type. The 29 aircraft make up almost half of the Europe of the airline fleet. These come from the canadian firm Bombardier, has sold its medium-haul jets, in the meantime, to Airbus. Therefore, the machine also received the Airbus nomenclature A220. The engines are manufactured by Pratt & Whitney. (red./sda)
