Sumitomo Precision Products has delivered its first landing gear to Mitsubishi Aircraft for its MRJ regional jet programme.

The landing gear will be loaded on the aircraft's iron bird rig for in-house function tests and will not be used on the flight test aircraft, says Mitsubishi.

The landing gear delivered consists of components such as shock strut, tire assembly and braking system. It was delivered after design and manufacturing phases following the engineering specifications issued by Mitsubishi.

The gear's basic mechanical movements and interfaces with electronic signals will be confirmed repeatedly during tests to ensure its durability. The tests will be conducted at Mitsubishi Heavy Industries' test facility in Nagoya, says the airframer.

With the delivery of this landing gear, Mitsubishi will also be able to conduct advanced tests on the iron bird preparing for the first flight.

"The delivery of this landing gear and related systems required both large-scale and highly precise, complex manufacturing procedures, the achievement of which is testimony to the steady progress of the MRJ programme," says Mitsubishi.

In April, Mitsubishi announced that the first flight of the MRJ will be delayed by over a year to the fourth quarter of 2013. Its first delivery has also been pushed back by a year to the summer of 2015.

The airframer said that it needed to "confirm respective fabrication processes" and to "provide sufficient time for technical studies", hence the delay.
