Emergency responders were searching for a small plane carrying five people that crashed in a rural part of New York State outside the Catskill Park on Sunday afternoon, the authorities said.
The plane, a single-engine Piper PA-46, crashed around 2 p.m., the Federal Aviation Administration said. The National Transportation Safety Board is leading an investigation.
It was not immediately clear what caused the crash or whether there were any injuries or fatalities. The search was initially focused on an area near Trout Creek, N.Y., which is about 45 minutes east of Binghamton, N.Y.
Sarah Taylor Sulick, a public affairs specialist at the N.T.S.B, said that “it’s our understanding that the plane has not yet been located and the local authorities are conducting a search.”
Dallis Wright, deputy coordinator for Delaware County Emergency Services, said emergency dispatchers received multiple calls Sunday that there was a plane in distress that appeared to be going down.
The National Weather Service in Binghamton issued a request for a spot forecast at around 2:30 p.m. for an aircraft search in Delaware County.
Multiple responders from local and state law enforcement agencies and fire and emergency services departments were on the ground on Sunday, using all-terrain vehicles, searching for the plane, Ms. Wright said.
A helicopter that provides critical care to patients throughout New York and Pennsylvania was also on the scene.
The missing plane left Albert S. Nader Regional Airport in Oneonta, N.Y., with five people aboard, the F.A.A. said. The plane’s final destination was not immediately clear.
