Narrative Report
On January 30, 2006 at 06:29 PM, Olathe - Palwaukee experienced a crash involving Cessna 421B Golden Eagle II, operated by H K Golden Eagle Inc., with the event recorded near Chicago-Executive (Palwaukee) Illinois.
The flight was categorized as private and the reported phase was landing (descent or approach) at a airport (less than 10 km from airport) 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: 1, crew fatalities: 1, passengers on board: 3, passenger fatalities: 3, other fatalities: 0.
The listed crash cause is human factor. The airplane was destroyed and the occupants fatally injured when it impacted the ground during approach to landing. Examination of the airplane, its engines and propellers, revealed no anomalies that were determined to have existed prior to impact. The propellers were found to have been in their normal operating range and neither propeller was in a feathered position. The quill shafts of both engines showed evidence of damage due to the production of torque. A sound spectrum examination of audio transmissions showed signatures that both engines were operating during the last two radio transmissions from the airplane. Based on radar data, communications and meteorological information obtained during the investigation, the airplane was operating in visual meteorological conditions below an overcast layer of clouds. The radar data showed the airplane as it approached the airport and as it entered a left hand traffic pattern for runway 34. Radio communications confirmed that the airplane had been cleared for a left hand traffic pattern to runway 34. The radar data showed the airplane as it made a turn to the left while its speed decreased to about 82 knots calibrated airspeed as of the last received radar return. This radar return was about 0.1 nautical miles from the accident site and 0.8 nautical miles and 216 degrees from the approach end of runway 34. The airplane owner's manual listed stall speeds ranging from 81 to 94 knots calibrated airspeed for airplane configurations including gear and flaps up to gear down and flaps 15 degrees, and bank angles from 0 to 40 degrees. Flap position could not be determined because the flap chain had separated from the flap drive motor. The owner's manual also listed an approach speed of 103 knots.
Aircraft reference details include registration N920MC, MSN 421B-0884, year of manufacture 1974.
Geospatial coordinates for this crash are approximately 42.1172°, -87.9013°.
