Air traffic control gave a low-altitude warning with no response before U.S. Bancorp executive Terry Dolan’s private plane crashed into a Brooklyn Park home last month, according to a federal aviation report released Friday.
A controller inside the Anoka County-Blaine Airport tower last heard Dolan — the pilot and sole person killed in the crash — acknowledge clearance to land at Runway 9 and verify the latest weather information.
As the Socata TBM700A plane began a sharp descent, Dolan failed to respond when the control tower issued a low-altitude warning and a second attempted communication three minutes later, according to the preliminary findings of the National Transportation Safety Board (NTSB).
Investigators evaluating the wreckage discovered no immediate signs of a mechanical issue with the engine or airframe, according to the report. The continuity of the flight control system was also established, the report says.
The federal NTSB released its first report since Dolan crashed his plane on March 29. He had been flying home from Naples, Fla., and stopped in Des Moines, Iowa, to refuel.
The investigation of the crash remains ongoing. The report Friday identified no probable causes and contained no medical information about Dolan.
The crash occurred a few miles from where Dolan kept his airplane at the Anoka-Blaine Airport, which houses recreational and corporate aircraft. Dolan held a private pilot license since October 2008, according to Federal Aviation Administration (FAA) records.
The airplane was flying at 3,000 feet above sea level when descent began roughly five nautical miles from the airport, according to data analyzed by NTSB investigators. Then its airspeed and descent rapidly increased as the airplane took a left turn.
