Narrative Report
On October 15, 2006 at 01:03 PM, Oklahoma City - Orlando experienced a crash involving Rockwell Grand Commander 690, operated by Jon Peter Olsen, with the event recorded near Antlers Oklahoma.
The flight was categorized as private and the reported phase was flight at a plain, valley crash site.
4 people were known to be on board, 4 fatalities were recorded, 0 survivors were identified or estimated. This corresponds to an estimated fatality rate of 100.0%.
Crew on board: 2, crew fatalities: 2, passengers on board: 2, passenger fatalities: 2, other fatalities: 0.
The listed crash cause is human factor. Approximately 37 minutes after departing on a 928-nautical mile cross-country flight under instrument flight rules, the twin-engine turboprop airplane experienced an in-flight break-up after encountering moderate turbulence while in cruise flight at the assigned altitude of FL230. In the moments preceding the break-up, the airplane had been flying approximately 15 to 20 knots above the placarded maximum airspeed for operations in moderate turbulence. The airplane was found to be approximately 1,038 pounds over the maximum takeoff weight listed in the airplane's type certificate data sheet (TCDS). The last radar returns indicated that the airplane performed a 180-degree left turn while descending at a rate of approximately 13,500 feet per minute. There were no reported eyewitnesses to the accident. The wreckage was located the next day in densely wooded terrain. The wreckage was scattered over an area approximately three miles long by one mile wide. An examination of the airframe revealed that the airplane's design limits had been exceeded, and that the examined fractures were due to overload failure.
Aircraft reference details include registration N55JS, MSN 690-11195, year of manufacture 1974.
