FLUVANNA COUNTY, Va. (CBS19 NEWS) -- The National Transportation Safety Board has released its preliminary report on a plane crash that killed two people in Fluvanna County earlier this month.

The crash occurred just before 9 a.m. on May 5, killing the pilot and a passenger.

Preliminary air traffic control information shows the Rockwell International 690A was at a cruise altitude of 20,000 feet when it reversed its course.

A controller asked the pilot if there was a problem and was reportedly told that the plane’s autopilot system stopped working.

Officials say there were no further communications from the plane.

A witness told NTSB and Federal Aviation Administration investigators that he was in his house when he heard a thunder-like noise that got louder.

When he went outside and looked up, he saw a plane flying “on its left side and on fire in the middle.”

The plane crashed into trees and the ground in a wooded area across the street from the witness’ house on Miles Jackson Road.

The report says the wreckage was scattered over three and a half miles.

The left wing, left engine, and left propeller were badly burned. These pieces were all found at the main wreckage site.

The right wing was found about a quarter of a mile north. It was also fire damaged.

The right engine and propeller have not been found.

The plane’s vertical and horizontal stabilizers were found about ¾ of a mile north of the main wreckage site.

NTSB says preliminary weather observations showed cloudy conditions in the area from the surface to above 30,000 feet.

There was also the potential for rime and mixed icing between 12,000 feet and 25,000 feet.

The pilot has been identified as 63-year-old John Latham, and the passenger has been identified as 73-year-old Niiben Ayivorh.
