The maker of Japan's first jet airliner is counting on bullet train specialists to prevent further delays in completing the plane.

Mitsubishi Aircraft Corp. has brought in rail project managers from parent Mitsubishi Heavy Industries Ltd. to tighten control of the Mitsubishi Regional Jet project and boosted engineers on the project by 30 percent to 1,300, President Teruaki Kawai said in a recent interview.

The moves are to help prevent the development bottlenecks that have slowed the commercial plane's introduction by about four years.
