From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Aircraft engine failed while holding, crashed in a wooded area. (.4)the dual student stated that they were holding in IMC conditions at 4,000 feet mean sea level (MSL) when minneapolis air route traffic control center (ARTCC) cleared them for the approach. ' we were told overfly the airport at 4,000 feet on the localizer back course and then intercept the ILS. As I left the holding pattern, the engine shook violently for 2 to 3 seconds, followed by complete engine failure. I established a glide and declared an emergency with ARTCC.' The pilots attempted to restart the engine. The airplane broke out of the clouds at approximately 500 feet above the ground and over a forest. The dual student said, 'I looked for the least dense area and headed for that site. We began encountering the trees just as I was attempting to stall the plane. We came to rest in a wooded, swampy area.' Examination of the wreckage revealed no anomalies. According to department of transportation/FAA/CT-82/44 publication: light aircraft piston engine carburetor ice detector/warning device sensitivity/effectiveness, June 1982, caruretor icing probability chart; the temperature (21 degrees fahrenheit) and dew point (16 degrees fahrenheit) at the time the airplane lost power places the probability for carburetor icing in the 'icing-glide and cruise power' area of the chart. (-23) while holding in IMC at a power setting of 2200 RPM engine lost power to 900 RPM. The pilot stated he accomplished the emergency checklist including the application of carb. Heat to no avail. The aircraft impacted and skidde through 60 yards of 11/2 to 2" diameter trees. The impact sheared off the nose gear, bent the prop, collapsed both left and right wing leading edges and sheared off 18" of the right stabilizer. Post accident investigation and inspection of the engine by FAA inspector c. ebert indicated the engine started and ran normal.
