Несчастный А-340 в Тулузе

Выдержка из официального документа Airbus, выпущенного после аварии в Тулузе.

    FOR ABOUT 3 MINUTES BEFORE THE END OF THE EVENT, ALL FOUR ENGINES EPR WAS BETWEEN 1.24 AND 1.26 WITH PARKING BRAKE ON AND WITHOUT GROUND CHOCKS. THE ALTERNATE BRAKE PRESSURE WAS NORMAL. (WITH PARKING BRAKE ON, BRAKE PRESSURE IS SUPPLIED BY ALTERNATE).
     13 SECONDS BEFORE THE IMPACT THE AIRCRAFT STARTED TO MOVE. WITHIN 1 OR 2 SECONDS THE CREW APPLIED BRAKE PEDAL INPUTS AND SELECTED PARKING BRAKE OFF. THESE ACTIONS LED THE NORMAL BRAKE PRESSURE TO INCREASE TO ITS NORMAL VALUE.
     2 SECONDS PRIOR BEFORE THE IMPACT, ALL 4 ENGINE THRUST LEVERS WERE SELECTED TO IDLE.
     THE AIRCRAFT IMPACTED THE CONTAINMENT WALL AT A GROUND SPEED OF 30 KTS.

     THERE IS NO EVIDENCE OF ANY AIRCRAFT SYSTEM OR ENGINE MALFUNCTION.
     AIRBUS REMINDS ALL OPERATORS TO STRICTLY ADHERE TO AMM PROCEDURES WHEN PERFORMING ENGINE GROUND RUNS. ENGINE GROUND RUNS AT HIGH POWER ARE NORMALLY CONDUCTED ON A SINGLE ENGINE WITH THE ENGINE IN THE SAME POSITION ON THE OPPOSITE WING OPERATED AT A LIMITED THRUST SETTING TO AVOID DAMAGE TO THE AIFRAME.

     WHEEL CHOCKS ARE TO BE INSTALLED THROUGHOUT THE TEST.


В двух словах - никаких отказов не было, двигатели гоняли без установки колодок под колеса...
