Aviation Accident Preliminary Report -  National Transportation Safety Board: 

Location: Kodiak, AK
Accident Number: ANC16LA062
Date & Time: 09/09/2016, 1130 AKD
Registration: N91AK
Injuries: 3 Serious
Flight Conducted Under: Part 135: Air Taxi & Commuter - Non-scheduled

On September 9, 2016, about 1130 Alaska daylight time, a float-equipped, de Havilland DHC-2 (Beaver) airplane, N91AK, sustained substantial damage during a collision with water, following a loss of control shortly after takeoff from Uganik Lake, about 35 miles west-southwest of Kodiak, Alaska. The airplane was registered to Redemption, Inc., Kodiak, and operated as Flight 43 by Island Air, Kodiak, as a visual flight rules (VFR) scheduled commuter flight under the provisions of 14 Code of Federal Regulations (CFR) Part 135.  Of the three occupants on board, the commercial pilot and two passengers all sustained serious injuries. Visual meteorological conditions prevailed, and company flight following procedures were in effect. Flight 43 originated in Kodiak about 1100, with a preplanned, intermediate stop at Uganik Lake, before continuing to the flights scheduled stops in Amook Bay and Zachar Bay, Alaska.

During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on September 9, the operator's director of maintenance stated that the purpose for the intermediate stop at Uganik Lake was to drop off a maintenance technician. He added that a company owned Cessna 185 had landed at Uganik Lake earlier in the day and damaged a float, and the maintenance technician was called in to inspect the float prior to the airplane returning to Kodiak. He said that after landing, the accident pilot met the crew of the Cessna 185 on the western shore of Uganik Lake, where he dropped off the maintenance technician, and then he then departed for Amook Bay. 

Witnesses reported seeing the accident airplane back-taxi to the east before it eventually turned around to start the takeoff run to the west, and towards an area of rising, tree-covered terrain. The witnesses consistently reported that after the airplane became airborne, it began a gradual left turn to avoid the rising terrain ahead. As the airplane flew closer to the rising terrain, the left turn steepened, and the airplane began a steep nose down descent. The airplane subsequently struck the shallow waters on the western end of Uganik Lake, and it came to rest partially submerged. The airplane sustained substantial damage to the wings and fuselage.  

The witnesses reported gusty wind conditions, from the west, estimated to be between 15 to 25 knots.

Coast Guard assets based in Kodiak rescued three people Friday after an aircraft crashed near the island community.

Watchstanders at the 17th Coast Guard District command center were alerted to the crash by an electronic locator beacon from a de Havilland Canada DHC-2 Beaver floatplane at 12:20 p.m., according to a Coast Guard release.

The beacon placed the floatplane crash near Unigak Lake, located on Kodiak Island about 35 miles southwest of Kodiak.

Two Coast Guard aircrews responded, arriving at the scene of the crash at about 1:30 p.m.

One of the survivors, a woman whose name wasn't given, was hoisted onto a rescue helicopter and flown to Kodiak Municipal Airport, where emergency medics were waiting, the Coast Guard said.

A rescue swimmer with one of the crews assessed and cared for the two remaining survivors. One had possibly broken a hip while the other suffered a head injury, officials said.

Weather near the crash was reported to be winds around 20 miles per hour and 10 miles of visibility.

An official with the National Transportation Safety Board could not immediately be reached Friday evening.
