NAGOYA, Japan - Flight tests carried out by the initial Mitsubishi Regional Jet (MRJ) test aircraft on August 27 and 28 were aborted when anomalies were detected in the signals generated by sensors monitoring the aircraft's air management systems. Two air management systems are installed in the aircraft, and a malfunction was detected in the sensors monitoring the system on the left side of the aircraft.
The air management systems did operate properly during the flights. However, Mitsubishi decided to postpone the aircraft's planned ferry flight to the United States, in order to take all possible measures to fly the MRJ in perfect condition.
Mitsubishi said that it will work with related parties to promptly move forward with the ferry flight, after completing an inspection and necessary measures.
