# NTSB ANC06CA010: Cessna 180H, N91399, Anchorage, AK, November 20, 2005 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: November 20, 2005, 12:30 local (16:30 UTC) - Place: Anchorage, AK - Coordinates: 61.213611, -149.844451 - Nearby events: https://openairdocs.org/map.md?lat=61.2136&lon=-149.8445&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report February 28, 2006 - Report: Approved by Office Director - NTSB office: Alaska Regional Office - NTSB case key (mKey): 62855 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ANC06CA010 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/62855/pdf - Page: https://openairdocs.org/ntsb/ANC06CA010 ## Probable cause The pilot's failure to maintain directional control during the takeoff roll, which resulted in the airplane encountering a snow berm, and nosing over. A factor associated with the accident was the snow berm. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - roll/run - directional control - not maintained, pilot in command (cause) - On ground/water encounter with terrain/water, takeoff - roll/run - terrain condition - berm (contributing factor) - Nose over, takeoff - roll/run ## Analysis The solo private pilot of the Title 14 CFR Part 91 flight was taking off to practice touch and go landings in a tailwheel equipped airplane. The pilot reported the wind was from the left at 5 knots, and as he began the takeoff roll, the airplane veered to the left, and he was unable to maintain directional control. The airplane subsequently collided with a snow berm on the left side of the runway and nosed over. He said there were no known mechanical anomalies with the airplane prior to the accident. The airplane received damage to the right wing, vertical stabilizer, and propeller. ## Factual narrative The solo private pilot of the Title 14 CFR Part 91 flight was taking off to practice touch and go landings in a tailwheel equipped airplane.
