Four people were uninjured Saturday when the single-engine plane they were traveling in landed in a field in Shirley, officials said.

According to Police Chief Steve Januszkiewicz, the Mastic Fire Department responded to an accident report at the corner of Sunset Drive and Forrest Avenue shortly before 4 p.m.

“They eventually flew through the fence and landed in a field next to the property,” he said at Brookhaven Calabro Airport. “Everyone was outside, there were four occupants, they all came out unharmed.”

A Suffolk County police spokesman confirmed a report of a plane crash at 3:53 p.m., but did not provide details of the incident or the identity of the pilot.

It is unclear if the plane took off or landed at Calabro Airport. According to the Federal Aviation Administration, the plane is registered to a company in Patchogue.

In a statement Saturday, FAA officials confirmed that the single-engine Piper PA-24 with four people on board landed in the field. The agency is investigating the incident, officials said.

Januszkiewicz said about 25 volunteer firefighters and Mastic Ambulance responded to the call with two fire trucks. Crews worked to contain a small fuel spill, he said.

“We have just confirmed that the power has been turned off and the fuel lines have been shut off,” he said.

The two-runway airport is maintained by the City of Brookhaven General Aviation Department and sees more than 50,000 takeoffs and landings each year, according to the city’s website.
