National Transportation Safety Board releases preliminary report on Collinsville plane crash

The National Transportation Safety Board has released its preliminary report of a April 7 plane crash in downtown Collinsville.

The small plane had left Tulsa International Airport  April 7 on its way to Manhattan Regional Airport in Kansas, when it went down in the backyard of a vacant home in Collinsville.

Chris Gruber, Kansas State University director of development for the College of Veterinary Medicine and Ronald Marshall, a retired doctor from Manhattan, Kan. and the plane's registered owner, were killed in the crash.

The report found that communications with TUL were normal "with the last acknowledgment from the pilot was that the airplane was cleared to 6,000 feet." No emergency or distress calls were sent from the pilot prior to the crash.

An FAA spokesperson said air control originally lost contact with the airplane about seven minutes after it took off, then lost a visual of the plane on its radar about nine miles north of Tulsa.

NTSB reported the aircraft reached 4,100 feet before a descending right turn, was seen on the radar. During that turn, the plane disappeared from the radar.

The NTSB report shows the airplane's impact left a crater about 10 feet in diameter and about four feet deep. Pieces of the plane were found in the crater and scattered around the area.

"A post-crash fire consumed part of the fuselage and rear stabilizer," NTSB reports.

The NTSB investigation is ongoing.
