• N68088 Iliamna Air Taxi Inc, Iliamna, AK. Regd 18-Jul-1994.
Accident: Iliamna, AK. 22-Jul-2009. The pilot was departing from a river, downstream, in the float-equipped airplane, on a Title 14, CFR Part 135, on demand charter flight. He said that wind conditions were calm just before starting his southerly takeoff run. Just after takeoff, as the airplane climbed to about 20 feet above the water, it stopped climbing as it neared the departure end of the site. The airplane then descended into an area of tree-covered terrain, and came to rest about 400 feet from the bank of the river. The airplane sustained substantial damage to the wings, fuselage, and empennage. The pilot reported that there were no pre accident mechanical anomalies with the airplane, and said that after the accident, he noticed occasional gusts of wind from the northwest.
The NTSB determines the probable cause(s) of this accident as the pilot's selection of an unsuitable landing/takeoff area with an unfavourable wind. ANC09CA050.
