CHINO, CA (AP) — Authorities say nobody was hurt when a small passenger jet with three people on board struck a hangar while taxiing at Chino Airport.

Federal Aviation Administration Ian Gregor says the pilot apparently lost control during an engine test Thursday.

The San Gabriel Valley Tribune reports mechanics were checking the engine, and plane's tires were on chocks. For an unknown reason, the jet came off the chocks, and it crashed halfway into the hangar at the Encore Jet Center.

Firefighters shut off electricity because of a concern of leaking fuel, but no leak was confirmed.

Four adjacent hangars and businesses within those hangars were evacuated. No injuries were reported.

The incident is under investigation.
