Narrative Report
On January 10, 1988 at 10:17 AM, Pontiac - Pontiac experienced a crash involving Swearingen SA226T Merlin III, operated by American Way Service Corporation, with the event recorded near Pontiac-Oakland County Michigan.
The flight was categorized as training and the reported phase was takeoff (climb) at a airport (less than 10 km from airport) crash site.
3 people were known to be on board, 3 fatalities were recorded, 0 survivors were identified or estimated. This corresponds to an estimated fatality rate of 100.0%.
Crew on board: 3, crew fatalities: 3, passengers on board: 0, passenger fatalities: 0, other fatalities: 0.
The listed crash cause is technical failure. Aircraft was scheduled for an instructional flight. During the weather briefing, the CFI told the FSS specialist that the flight would include engine out practice. Witness statements indicate that the aircraft rolled sharply to the right and nosed down after attaining about 100 feet of altitude during the climb after takeoff. The aircraft struck the ground left prop and left wing tip first, in an inverted flight attitude. During the post accident investigation, the right engine power lever was subjected to lab exam and it was found that the lower aft part of the lift gate detent was worn. This created a ramping effect between the rounded edge of the lift gate and the flight idle stop. A worn lift gate detent would allow the power lever to inadvertently be moved into the beta range, causing asymmetrical drag and degraded airplane performance, particularly in critical phases of flight. All three occupants were killed.
Aircraft reference details include registration N800AW, MSN T-403, year of manufacture 1981.
Geospatial coordinates for this crash are approximately 42.6389°, -83.2910°.
