# NTSB SEA07CA219: Cessna 170 B, N3446C, Arco, ID, July 28, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: July 28, 2007, 01:15 local (07:15 UTC) - Place: Arco, ID - Coordinates: 43.605556, -113.334724 - Nearby events: https://openairdocs.org/map.md?lat=43.6056&lon=-113.3347&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report November 29, 2007 - Report: Approved by Office Director - Parties: Boise Flight Standards District Office - NTSB case key (mKey): 66321 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA07CA219 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/66321/pdf - Page: https://openairdocs.org/ntsb/SEA07CA219 ## Probable cause The pilot's failure to maintain directional control during takeoff. The crosswind condition was a factor. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - directional control - not maintained, pilot in command (cause) - weather condition - crosswind (contributing factor) - In flight collision with object, takeoff - object - fence - On ground/water encounter with terrain/water, emergency landing - ground loop/swerve - intentional, pilot in command - terrain condition - rough/uneven ## Analysis The pilot reported that he initiated the takeoff roll on runway 24, with the wind estimated to be from 315 degrees at 8-10 knots. After sufficient acceleration, the pilot moved the yoke forward in order to raise the tailwheel off the ground. As the tail began to rise, the aircraft immediately became airborne and "aggressively drifted" to the left. The pilot was unable to correct for the deviation, and flew towards the south, away from the runway heading. The aircraft then flew over a 10 foot deep depression in the ground and descended. At the end of the depression, where the terrain rose back up to ground level, the aircraft impacted a barbed wire fence. The pilot was able to set the aircraft down in a small clearing past the fence, but due to a sloped area ahead, the pilot intentionally ground looped the aircraft to the right. The aircraft nosed over, coming to rest inverted. ## Factual narrative The pilot reported that he initiated the takeoff roll on runway 24, with the wind estimated to be from 315 degrees at 8-10 knots.

(-23) Pilot encountered gusting right crosswind during takeoff roll, causing aircraft to drift left despite attempts to apply corrective controls. Aircraft… From the NTSB's public API. 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.
