Mitsubishi Heavy Industries Ltd. is considering sharply scaling back its staff and budget for developing the first domestically manufactured passenger jet, effectively freezing the operation amid a slump in demand caused by the novel coronavirus pandemic, sources close to the matter said Thursday.

The Japanese firm's subsidiary Mitsubishi Aircraft Corp. has been developing a small aircraft called the Mitsubishi SpaceJet, previously known as the Mitsubishi Regional Jet. Its initial delivery to All Nippon Airways Co., originally planned for 2013, has been postponed to 2021, or possibly later, due to problems with parts and a lack of technical experts.

The new passenger jet, if successfully launched, would be the first commercial aircraft manufactured in Japan in half a century following the YS-11 turboprop plane by Nihon Aircraft Manufacturing Corp.

Mitsubishi Heavy is expected to announce the decision on Oct. 30 when it unveils a new medium-term business strategy, the sources said.

Delivery of the Mitsubishi SpaceJet has been delayed six times so far despite around 1 trillion yen ($9.6 billion) having already been poured into the development of the airplane.

The SpaceJet is designed to carry around 90 passengers with what the company calls "game-changing" fuel efficiency. Mitsubishi Heavy will likely continue aiming for a type certificate for the jet, the sources said.

In the business year through last March, Mitsubishi Heavy posted an operating loss for the first time in two decades due to ballooning SpaceJet development costs.

In May, President Seiji Izumisawa said the company would review the development schedule "as a whole" and unveiled a plan to more than halve spending for the project to about 60 billion yen in fiscal 2020 through next March.

Mitsubishi Heavy is likely to decide what to do with the regional jet development while assessing the demand for flights.

Even before the coronavirus pandemic, many airline companies had shifted their focus to smaller aircraft due to their fuel efficiency amid rising awareness of climate change.

But airlines are now struggling as the pandemic has led many countries to impose travel restrictions.

Mitsubishi Heavy, a manufacturer of fighter jets and rockets, launched the regional jet project in 2008 and the maiden flight took place in November 2015.
