# NTSB ANC03LA113: Cessna 206, N710MH, Chalkyitsik, AK, September 11, 2003 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: September 10, 2003, 18:00 local (Sep 11, 2003, 02:00 UTC) - Place: Chalkyitsik, AK - Coordinates: 68.476112, -142.442504 - Nearby events: https://openairdocs.org/map.md?lat=68.4761&lon=-142.4425&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor, 2 uninjured - Status: Completed, report April 28, 2004 - Report: Approved by Office Director - NTSB office: Alaska Regional Office - Parties: Federal Aviation Administration - NTSB case key (mKey): 57920 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ANC03LA113 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/57920/pdf - Page: https://openairdocs.org/ntsb/ANC03LA113 ## Probable cause The pilot's inadequate compensation for wind conditions, and his failure to maintain adequate airspeed during takeoff, which resulted in an in-flight collision with brush, and subsequent stall of the airplane. Factors associated with the accident were a crosswind, high vegetation (brush), and an inadvertent stall. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with terrain/water, takeoff - initial climb - terrain condition - high vegetation (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - weather condition - crosswind (contributing factor) - Loss of control - in flight, takeoff - initial climb - airspeed(vs) - not maintained, pilot in command (cause) - stall - inadvertent, pilot in command (contributing factor) - In flight collision with terrain/water, descent - uncontrolled - terrain condition - rough/uneven ## Analysis The commercial pilot was departing from a 1,500 foot-long gravel-covered site, which required a correction for a strong right crosswind. Just after takeoff, the airplane drifted to the left, and the main landing gear wheels struck a stand of brush. The airplane subsequently descended towards an area of rough and uneven terrain. As the pilot was attempting to gain altitude, the airplane stalled, and the nose wheel struck a large ditch at the departure end of the site. The airplane nosed over, and sustained structural damage to the wings, fuselage, and empennage. According to the company owner, there were no preaccident mechanical anomalies with the airplane. ## Factual narrative On September 10, 2003, about 1800 Alaska daylight time, a wheel-equipped Cessna 206 airplane, N710MH, operated by Circle Air, Central, Alaska, as a Title 14, CFR Part 135 on-demand charter flight, sustained substantial damage when it collided with an area of rough, uneven terrain and nosed over during an attempted takeoff from a remote off-airport site located about 100 miles northeast of Chalkyitsik, Alaska. The flight operated in day visual meteorological conditions, and company flight following procedures were in effect. Of the three people aboard, the commercial certificated pilot and one passenger received no injuries; the other passenger sustained a minor injury. The flight originated at the off-airport site, and was en route to the Circle Hot Springs Airport, Circle, Alaska. In a written statement, the owner of the company reported that the pilot was departing from a 1,500 foot-long gravel-covered site, which required a correction for a strong right crosswind. She reported that just after takeoff, the airplane drifted to the left, and the main landing gear wheels struck a stand of brush, and the airplane began to descend onto an area of rough and uneven terrain. She said that as the pilot was attempting to gain altitude, the airplane stalled, and the nose wheel struck a large ditch at the departure end of the site. The airplane subsequently nosed over, and sustained structural damage to the wings, fuselage, and empennage. According to the company owner, there were no preaccident mechanical anomalies with the airplane. ## Aircraft - Registration: [N710MH](https://openairdocs.org/aircraft/N710MH), registered now, S/N U20602383, built 1974 (OpenAirDocs) - Reported make and model: Cessna 206 - Registry model: [Cessna U206F](https://openairdocs.org/model/cessna-u206f) (registry code 2073333) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: U20602383 - Airframe hours: 3692 - Engines: Continental IO-520-F 300 horsepower reciprocating - Damage: Substantial damage - Flight: Part 135 - Operator: Dawn E.
