The National Transportation Safety Board released preliminary findings in the investigation of a fatal plane crash near Perry on July 1.
A review of Federal Aviation Administration air traffic control records showed the 1987 Beech Bonanza was climbing from 7,000 feet to 14,000 feet when the pilot reported losing an engine.
Air traffic control lost radar contact with the plane and all communications at 1,000 feet.
The small plane crashed nose-first into a field in rural Jefferson County in clear weather, the NTSB report said.
New York couple Gregory Collis, 56, and his wife, Pindi Williams, 54, were both killed on impact.
Investigators found the plane’s propeller buried about a foot into the ground.
The plane’s wreckage was transported to a secure hangar for further investigation.
The plane had taken off from Charles B. Wheeler Downtown Airport in Kansas City and was on its way to St. Johns Industrial Air Park in St. John’s Ariz.
