# NTSB CHI06CA222: Rockwell S2R, N7982V, Park Rapids, MN, July 30, 2006 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Data collection · Final report - Date: July 30, 2006, 07:30 local (12:30 UTC) - Place: Park Rapids, MN - Coordinates: 46.900554, -95.073059 - Nearby events: https://openairdocs.org/map.md?lat=46.9006&lon=-95.0731&mi=10 - Phase of flight: [Maneuvering](https://openairdocs.org/ntsb-phases/450) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report October 31, 2006 - Report: Approved by Office Director - Parties: Minneapolis, MN - NTSB case key (mKey): 64332 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI06CA222 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/64332/pdf - Page: https://openairdocs.org/ntsb/CHI06CA222 ## Probable cause A loss of engine power for undetermined reasons and the inadequate airspeed during the forced landing which resulted in a stall/mush. A factor was the low altitude at which the airplane was being operated. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, maneuvering - aerial application - altitude - low (contributing factor) - reason for occurrence undetermined (cause) - Forced landing, emergency descent/landing - In flight collision with terrain/water, descent - uncontrolled - airspeed - inadequate, pilot in command (cause) - stall/mush - Nose down, other ## Analysis The airplane collided with the terrain and nosed down, following a loss of engine power during an aerial application flight. The pilot reported he made two swath runs over the field he was spraying. He stated that during the turn at the end of the second pass, the engine started to lose power. The pilot reported that he made a turn to the right to avoid a farm and checked the magnetos to no avail. He stated that he made another turn to avoid another farm and trees along the flight path. The pilot reported that he decided to land in a pasture and that turbulence was encountered when the airplane descended below the tree level. He reported that the airplane impacted the ground due to the loss of the headwind. The airplane contacted the terrain on the main gear, nosed down, and spun around 180 degrees before coming to rest. The reason for the loss of engine power was undetermined. ## Factual narrative The airplane collided with the terrain and nosed down, following a loss of engine power during an aerial application flight.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
