A pilot and passenger were killed in a single-engine plane crash as it approached the Hancock County-Bar Harbor Airport in Trenton on Thursday afternoon.

Maine State Police identified the pilot as Michael Leibowitz, 71, of Charleston, South Carolina, and the passenger as Christina Chung, 57, of Livingston, New Jersey.

The plane crashed and caught fire at the end of a runway, airport manager Leroy Muise said in a release. Regional first responder services were immediately notified and extinguished the fire before recovering the victims.

“We wish to thank all emergency response personnel from the many agencies that assisted us today, along with the members of the public that kindly detoured as requested,” Muise said in the statement.

The aircraft, a Cirrus SR22, is registered to Miller High Life Aviation LLC in Charleston, South Carolina, according to records from the Federal Aviation Administration.

It crashed around 12:25 p.m. and had taken off about two hours earlier from Morristown Municipal Airport in New Jersey. The cause of the crash remains under investigation by the National Transportation Safety Board, an FAA spokesperson said.

An investigator was expected Friday to examine the plane and document the scene, according to an NTSB spokesperson. The plane will then be recovered for further evaluation. Investigators will also review information like air traffic control communications, flight track data, weather reports, witness statements, and conduct a 72-hour background of the pilot to determine if they were safe to operate the flight.

The NTSB spokesperson said any witnesses or anyone with information that could be relevant to the investigation should contact the board at witness@ntsb.gov.

NTSB investigations take between one to two years, but a preliminary report with information is expected within 30 days of the accident.

A spokesperson for the sheriff’s office directed questions about the crash and victims to Maine State Police. Department of Public Safety spokesperson Shannon Moss said state police were assisted by the state fire marshal’s office, local fire departments and the Hancock County Sheriff’s Office. She referred additional questions to the FAA and NTSB.
