# NTSB ANC98LA090: Cessna 206G, N456TA, Aleknagik, AK, July 1, 1998 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: July 1, 1998, 15:45 local (23:45 UTC) - Place: Aleknagik, AK - Coordinates: 59.240711, -158.620498 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=59.2407&lon=-158.6205&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report July 2, 1999 - Report: Approved by Office Director - NTSB office: Alaska Regional Office - NTSB case key (mKey): 43061 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ANC98LA090 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/43061/pdf - Page: https://openairdocs.org/ntsb/ANC98LA090 ## Probable cause The pilot's failure to attain a proper touchdown point during landing. A factor associated with the accident is the presence of a variable wind condition, and the pilot's decision not to perform a go-around. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, landing - roll - weather condition - variable wind (contributing factor) - proper touchdown point - not attained, pilot in command (cause) - go-around - not performed, pilot in command (contributing factor) - Nose over, landing - roll - terrain condition - drop-off/descending embankment ## Analysis The certificated commercial pilot was landing on a remote gravel runway. During a telephone conversation with the National Transportation Safety Board investigator-in-charge, on July 1, 1998, the pilot reported that while landing to the west, he inadvertently flew further down the runway and landed about midfield of the 1,150 feet long runway. He stated that after touchdown he was unable to stop the airplane before it went down an embankment at the end of the runway, and nosed over. In his written statement to the NTSB dated September 1, 1998, the pilot reported that while landing to the west, he encountered an unexpected 'wind change' from the east. He said that the tailwind caused the airplane's ground speed to accelerate, and after touchdown, he was unable to stop prior to reaching the runway end. The airplane's left wing sustained substantial damage. ## Factual narrative On July 1, 1998, about 1545 Alaska daylight time, a wheel equipped Cessna 206G airplane, N456TA, sustained substantial damage while landing at the Aleknagik Airstrip, Aleknagik, Alaska.

In his written statement to the NTSB dated September 1, 1998, the pilot reported that while landing to the west, he encountered an unexpected "wind change" from the east. He said that the tailwind caused the airplane's ground speed to accelerate, and after touchdown, he was unable to stop prior to reaching the runway end. The airplane's left wing sustained substantial damage. The pilot noted that there were no preaccident mechanical anomalies with the airplane. ## Aircraft - Registration: [N456TA](https://openairdocs.org/deregistered/N456TA-2013-07-18), registration cancelled 2013-07-18, S/N U20605034, built 1979 (OpenAirDocs) - Reported make and model: Cessna 206G - Registry model: [Cessna U206G](https://openairdocs.org/model/cessna-u206g) (registry code 2073356) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: U2060503 - Airframe hours: 6746 - Engines: Continental IO-520F 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Arctic Circle Air, doing business as Arctic Circle Air - Registered owner: Arctic Air Group, Inc. - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, June 9, 1998, 61 hours before - Departed: DLG, DILLINGHAM, AK - Flight plan: VFR - Airport: Z35, Aleknagik Mission School, runway 27, 1,150 × 35 ft, gravel ## Flight crew As NTSB recorded them.

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.
