# NTSB ANC01LA005: Cessna 180, N9306C, Anchorage, AK, October 8, 2000 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: October 7, 2000, 18:10 local (Oct 8, 2000, 02:10 UTC) - Place: Anchorage, AK - Coordinates: 61.15979, -149.989654 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=61.1598&lon=-149.9897&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report July 10, 2001 - Report: Approved by Office Director - NTSB office: Alaska Regional Office - NTSB case key (mKey): 50488 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ANC01LA005 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/50488/pdf - Page: https://openairdocs.org/ntsb/ANC01LA005 ## Probable cause The pilot's delay in aborting the takeoff run. A factor associated with the accident was glassy water conditions. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Overrun, takeoff - aborted - terrain condition - water,glassy (contributing factor) - aborted takeoff - delayed, pilot in command (cause) - On ground/water collision with object, takeoff - aborted - terrain condition - dirt bank/rising embankment - object - aircraft parked/standing ## Analysis The certificated commercial pilot reported that as he started a southeasterly takeoff run, using the southeast water lane, the airplane's acceleration seemed slower than normal due to glassy water conditions. He said that as he neared the end of the water lane, just before the airplane became airborne, he elected to abort the takeoff run. He said that after he closed the throttle, the airplane stayed up on the step longer than he had anticipated, and subsequently struck the lakeshore, and a moored and unoccupied Cessna 185. The pilot said that there were no preaccident mechanical anomalies with the airplane. ## Factual narrative On October 7, 2000, about 1830 Alaska daylight time, a float equipped Cessna 180 airplane, N9306C, sustained substantial damage during takeoff from the Lake Hood Sea Plane Base, Anchorage, Alaska. The certificated commercial pilot, and the one pilot-rated passenger aboard, were not injured. The airplane was being operated as a visual flight rules (VFR) personal flight under Title 14, CFR Part 91, when the accident occurred. Visual meteorological conditions prevailed, and no flight plan was filed. During an on-scene interview with the National Transportation Safety Board investigator-in-charge on October 7, the pilot reported that as he started a southeasterly takeoff run, using the southeast water lane, the airplane's acceleration seemed slower than normal due to glassy water conditions. He said that as he neared the end of the water lane, just before the airplane became airborne, he elected to abort the takeoff run. He said that after he closed the throttle, the airplane stayed up on the step longer than he had anticipated, and subsequently struck the lakeshore, and a moored and unoccupied Cessna 185, N61473. The airplane sustained substantial damage to the left wing and fuselage. The pilot said that there were no preaccident mechanical anomalies with the airplane. ## Aircraft - Registration: [N9306C](https://openairdocs.org/aircraft/N9306C), registered now, S/N 31704, built 1955 (OpenAirDocs) - Reported make and model: Cessna 180 - Registry model: [Cessna 180](https://openairdocs.org/model/cessna-180) (registry code 2072602) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 31704 - Airframe hours: 3871 - Engines: Continental O-470-50 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Kent D.
