# NTSB LAX07CA132: Cessna U206-C, N29100, Cottonwood, ID, April 22, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: April 22, 2007, 12:00 local (18:00 UTC) - Place: Cottonwood, ID - Coordinates: 46.5, -116.433334 - Nearby events: https://openairdocs.org/map.md?lat=46.5000&lon=-116.4333&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report June 27, 2007 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 65636 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX07CA132 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/65636/pdf - Page: https://openairdocs.org/ntsb/LAX07CA132 ## Probable cause The pilot's misjudgment of distance/speed, which resulted in a overshoot of the runway in tailwind conditions and subsequent nose over. Factors in the accident were the tail wind condition and the short runway. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - roll - weather condition - tailwind (contributing factor) - terrain condition - short runway/landing area (contributing factor) - distance/speed - misjudged, pilot in command (cause) - Nose over, landing - roll - terrain condition - soft ## Analysis The airplane overran the landing strip and nosed over. As the airplane approached the destination, the pilot performed three passes over the airstrip and noted that the windsock indicated light winds (about 5 knots). In light of the airstrip having a slope, the pilot opted to land in an upslope direction with a tailwind on the 700-foot-long grass runway. On the landing roll he applied brake pressure, but was unable to stop before continuing off the landing strip surface. The airplane encountered deep, soft sand and nosed over, coming to rest inverted. The pilot exited the airplane and noted that the windsock indicated a moderate tailwind. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or engine. ## Factual narrative The airplane overran the landing strip and nosed over. In both a written statement and in oral interviews, the pilot reported that the purpose of the flight was for the non-paying passenger to take pictures at the destination airstrip. As the airplane approached the destination, the pilot performed three passes over the strip and noted that the windsock indicated light winds (about 5 knots). The airstrip was sloped upward to the south. The pilot opted to land to the south, with a tailwind. He made a normal approach and touchdown. On the landing roll he applied brake pressure, but was unable to stop before continuing off the landing strip surface. The airplane encountered deep sand and nosed over, coming to rest inverted. The pilot exited the airplane and noted that the windsock indicated moderate tail winds. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or engine. ## Aircraft - Registration: [N29100](https://openairdocs.org/deregistered/N29100-2013-10-29), registration cancelled 2013-10-29, S/N U206-1072, built 1968 (OpenAirDocs) - Reported make and model: Cessna U206-C - Registry model: [Cessna U206C](https://openairdocs.org/model/cessna-u206c) (registry code 2073332) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 1072 - Engines: Continental IO-520-F4B reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Departed: S80, Grangeville, ID - Destination: Cottonwood, ID - Flight plan: Company VFR - Airport: NONE, Salmon Bar, runway 18, 700 × 40 ft, grass/turf ## Flight crew As NTSB recorded them.
