Mitsubishi Aircraft Corp. announced on March 4 that test flights have started in the United States of its Mitsubishi Regional Jet (MRJ) 90, the first Japanese-made passenger jet.

The flights are being conducted as the company enters the final stages of getting clearance from the central government. In the tests, pilots from the transport ministry checked the operation of the jet's engines on March 3.

The testing was supposed to start at the end of January, but was delayed due to various reasons including the partial shutdown of the U.S. government, bad weather and a delay in preparing the jet, according to Mitsubishi Aircraft.

Mitsubishi Aircraft is aiming for starting delivery of its much-delayed 90-seat passenger jet in the middle of 2020.
