At about 10:20 AM local time, a Cirrus SR22 light aircraft collided in mid-air with Key Lime Air Flight 970, an air charter cargo flight from Salida, Colorado, operated by a Swearingen SA226-TC Metroliner over Cherry Creek State Park in Arapahoe County.

The collision destroyed a large section of the cabin of the Metroliner and damaged the empennage, but the pilot—who was the sole aircraft occupant and, based on communications with air traffic control (ATC), was initially unaware of the extent of the damage—was able to make a safe landing at Centennial Airport despite the significant damage to the fuselage and subsequent difficulties with the right-hand engine.

The pilot of the Cirrus, which was a private rental aircraft on a local flight from Centennial Airport, deployed the Cirrus Airframe Parachute System (CAPS) and made a safe parachute-assisted forced landing near Cherry Creek Reservoir; the pilot and single passenger were not injured.

[1][2] The National Transportation Safety Board determined that the accident was caused by failures of airmanship and ATC.

The SR22 pilot flew too fast in the airfield traffic pattern and overshot his turn, resulting in the SR22 crossing the extended centerline of the parallel runway where the Metroliner was on final approach for landing.
