A preliminary report by the National Transportation Safety Board stated that radar data showed that Greene's aircraft made a left turn, followed by a right turn and then a series of right, 360-degree turns before radar contact was lost at 10:13 a.m.
The plane was at an altitude of 7,400 feet. Greene left Snyder around 9 a.m. the same day that the aircraft went down.
The scene of the crash had a 1,000-foot debris path, according to the report, and noted that the wings, fuselage and tail section were extensively broken. Both blades of the propeller were discovered and the engine was located at the end of the path.
Searchers located the remnants of the plane and the bodies of Greene and Martinez on Nov. 30 in the northeast portion of the Mescalero Apache Reservation.
Rodger Sullenger, Winston Field Manager, previously said that Greene had contacted the Sierra Blanca Regional Airport to report he was turning around to return to Snyder after running into bad weather.
The NTSB report stated that visibility was seven miles with clouds at about 1,000 feet. Winds were 12 miles per hour.
A final report will be released after the investigation is concluded.
