Emergency crews responded after a two-engine plane landed without its landing gear at the Portland International Jetport Thursday morning.

By 10:45 a.m., the small aircraft was on the runway on its belly. Fire and emergency personnel surrounded the craft.

A city spokeswoman said no one was injured and there was no fire.

Runways at the Jetport will be closed for one to two hours until the plane can be removed, city spokeswoman Jessica Grondin said in an email.

Grondin advised passengers and people meeting them to check with individual airlines about delays.

Eight flights have been affected so far, either by being delayed, diverted or canceled, according to the Jetport’s website. Arriving flights have been diverted to Manchester, New Hampshire, or Boston.

The plane is registered to Air New England LLC of Waterville, a small commercial carrier, according the Federal Aviation Administration’s database. That model, a Beechcraft Baron 58, is a two-engine propeller driven plane that accommodates up to five passengers and cruises at around 210 mph.

This particular aircraft was first certified as airworthy in 1973, according to the FAA.

A woman who answered the phone at Air New England declined to offer comment and said questions were being referred to company executives.
