HISTORY OF FLIGHT On December 15, 2011, about 1530 Alaska standard time, a Cessna U206G airplane, N252AL, sustained substantial damage when it impacted ocean waters shortly after takeoff from Runway 01 at the Nanwalek Airport, Nanwalek, Alaska. The airplane was being operated by Smokey Bay Air, Homer, Alaska, as a visual flight rules (VFR) scheduled commuter flight under 14 Code of Federal Regulations Part 135. The pilot and three passengers sustained minor injuries. Visual meteorological conditions prevailed at the time of the accident, and company flight following procedures were in effect. The flight originated from the Homer Airport about 1445, with a stop in Port Graham, Alaska. In a written statement to the National Transportation Safety Board (NTSB), the pilot stated that the wind at the airport was from the east at 12 to 15 knots, and the runway was covered with approximately 3 inches of slush, with as much as 6 inches in the potholes. He said that there was enough contamination that extra power was required to taxi the airplane. During the takeoff roll on runway 01, the airplane’s acceleration was degraded due to the runway contamination, but it became airborne near the midpoint of the runway. He stated that as he was making a left turn, the airplane encountered a strong downdraft. With full power applied to the engine and the airplane’s pitch attitude set to best angle of climb, he said the airplane was still descending approximately 500 feet per minute. When he realized that the airplane was not going to climb, he reduced the engine power to idle and ditched the airplane approximately 100 feet from the shore. After the airplane entered the water, the pilot and three passengers evacuated the airplane through the pilot’s door and began to swim to shore, where they were assisted by local bystanders. Another pilot that was at the north end of the airport said he saw the airplane takeoff in a nose high attitude, “as you would expect of a soft-field takeoff.” He stated that the airplane continued in a very nose high attitude until it descended below his line of sight, at which time he went to his airplane and radioed another pilot flying in the area, and informed him that an airplane was down near Nanwalek. PERSONNEL INFORMATION The pilot, age 38, held a commercial pilot certificate with airplane single-engine land, multiengine land, and instrument airplane ratings. His most recent second-class medical certificate was issued on October 24, 2011, which contained the limitation that he must wear corrective lenses for distant vision. In the Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1) submitted by the operator, the pilot’s aeronautical experience was listed as 1,987 flight hours, with 462 flight hours in the accident airplane make and model. The report noted that in the preceding 90 and 30 days prior to the accident, the pilot accrued a total of 200 flight hours and 53 flight hours. A review of company training records revealed that the pilot completed his initial ground training on April 22, 2011. On April 26, 2011, the pilot completed his initial flight training in Cessna 206 airplanes. Once the pilot completed the company's training program and passed a check ride, the pilot was officially hired, then assigned to fly Cessna 206 airplanes from the company base in Homer. The pilot's most recent FAA Part 135.293 and 135.299 checks, administered by a FAA Operations inspector from the Anchorage Flight Standards District Office (FSDO), were on December 15, 2011, the morning of the accident flight. The pilot's normally scheduled duty day was from 0730 to 2130. In the three days prior to the accident, the pilot was off duty. On the accident date of December 15, the pilot started his duty day at 0730, and flew a total of 2.4 hours before the accident. AIRCRAFT INFORMATION The six-seat, high-wing airplane was manufactured in 1976. The airplane was equipped with a Continental IO-520-F engine, rated at 300 horsepower, driving a Hartzel 3-bladed, all-metal, constant-speed propeller (model number HC-C3YF-1RF). At the time of the accident, the airplane had a total time in service of 3,895 flight hours. A review of the maintenance records showed that maintenance personnel last completed an inspection of the airframe and engine under the continuous airworthiness inspection program on November 19, 2011. The engine had a total time in service of 1,245 hours at the last inspection. METEOROLOGICAL INFORMATION There is no official weather reporting at the Nanwalek airport. The nearest official weather reporting station is the Seldovia airport (PASO), 9 nautical miles northeast of Nanwalek. At 1453, the PASO Aviation Routine Weather (METAR) was reporting: Wind, 170 degrees (true) at 3 knots; visibility, 10 statute miles; sky condition, 5,000 feet scattered, 7,500 feet broken; altimeter, 29.19 inHg. At 1540, the PASO METAR was reporting: Wind, 170 degrees (true) at 10 knots, gusting to 15 knots; visibility, 4 statute miles in light rain; sky condition, 1,800 feet broken, 3,900 feet broken; altimeter, 29.21 inHg. An unofficial weather reporting station is located near the Nanwalek airport, and is used by pilots as supplemental weather information. At 1417, the unofficial weather station was reporting wind from 076 degrees (true) at 8 knots, gusting to 16 knots. COMMUNICATIONS There were no communications between air traffic control and the accident airplane. Another pilot employed by the operator was also on the ground at the Nanwalek airport when the accident airplane was arriving. The pilot on the ground reported that he relayed weather and airport conditions to the accident pilot over the Nanwalek UNICOM frequency. AIRPORT INFORMATION The Nanwalek airport is a public-use airport, owned and maintained by the State of Alaska. The airport is tightly constrained by terrain and water on all sides, and the 1,850 feet runway is not regularly maintained. The FAA Airport/Facility Directory, Alaska Supplement listing for the Nanwalek Airport contains the following notation: “Airport Remarks – Unattended. Runway 01-19 north 1,000 feet CLOSED indefinitely, remaining 850 feet soft.” The Alaska Department of Transportation closed the northern portion of the runway due to the fact that they deemed it unsuitable for operations, and that they had no way to provide adequate maintenance to keep the runway open. There is a contract maintenance provider in Nanwalek, and he stated that he did inspect the runway the morning of the accident, and determined that no maintenance was needed at that time. He said that the conditions were changing rapidly, and after the first airplane arrived at the airport later that day, he asked the pilot if the runway was adequate, and was told it was fine. According to the Nanwalek airport manager, it is at the contractor’s discretion to determine the runway conditions. The contractor also has the authority to issue Notices to Airmen (NOTAMs). The area surrounding the Nanwalek airport produces significant turbulence and downdrafts, especially when the prevailing wind is from the east. WRECKAGE AND IMPACT INFORMATION The airplane came to rest in the waters of English Bay, about 100 feet offshore from the northeast coast of Nanwalek. The airplane remained intact and upright, and all the airplane’s major components remained attached, with the exception of the right main landing gear wheel, which separated during the accident sequence. The right aileron and the right horizontal stabilizer were wrinkled and creased. ORGANIZATIONAL AND MANAGEMENT INFORMATION The operator is a Federal Aviation Regulations (FAR) Part 135 Air Carrier, and held scheduled commuter and on-demand operations specifications. Company facilities are in Homer. At the time of the accident, the listed Director of Operations (DO) lived in Homer, but was no longer involved with the day-to-day operations with the carrier, and they were in the process of naming a new DO. The Chief Pilot (CP) resided in Anchorage, Alaska, and regularly commuted to Homer to perform his duties. A review of the company's operations specification, issued by the FAA, indicate that flights shall only be initiated, diverted, or terminated under the authority of the director of operations, who may delegate his authority, but retains responsibility. At the time of the accident, the company president was out of town. Company Training Both initial and recurrent pilot training were accomplished in-house. Initial operating experience flights were conducted to the Nanwalek airport. In accordance with Part 135 requirements, Smokey Bay Air maintains an FAA-approved training manual. Operational Control At the time of the accident, the company used a two-pilot release method for dispatching and monitoring operational control of flights. Once it was determined that a flight was to be made, the information was passed along to the pilot-in-command (PIC) who along with another pilot, or the DO or CP in some circumstances, would determine if all the conditions for conducting that flight could be met. Under some circumstances, the DO or CP must be notified to release a flight. The company used a basic risk assessment form to determine the level of operational control needed for a specific flight. The risk assessment form prompted the pilot to look at five areas of risk (Pilot, Equipment, Weather, Runway Conditions, and Daylight Requirements), and assign each category a value (Green light, Yellow light, or Red Light). Pilots complete the risk assessment at the beginning of the day, and are required to reevaluate if any conditions change throughout the day. Any combination of 3 yellow light items required additional approval from the DO or CP. A red light item required the cancellation of the flight. (A copy of the risk assessment template is located in the public docket for this accident.) On the morning of the accident flight, the accident pilot, along with another company pilot, reviewed the weather in the area, and decided that no flights would be initiated. Around noon, the weather began to clear, so the two pilots exercised their operational control under the two-pilot release system, and flight began at approximately 1300. The two pilots completed the risk assessment form and assigned “green lights” for 4 of the 5 categories. A “yellow light” was assigned to the equipment category, but no note was made explaining the reason for the upgraded risk. A review of the risk assessment by the NTSB IIC showed that, for the conditions during the accident flight, 3 of the 5 categories should have been assigned a “yellow light” requiring additional approval from the DO or CP. Standard Operating Procedures At the time of the accident, Smokey Bay Air pilots were trained to the standard operating procedures contained in the company’s General Operations Manual. ADDITIONAL INFORMATION In the months after the accident, the operator made numerous changes to their operating procedures that benefited the safety of the flight operations. Including changes to their operational control mechanisms, having both the DO and CP in house, modifying their risk assessments, and revamping their safety policies to align with the FAA Safety Management System framework. The FAA Weather Camera Office has initiated installation of a weather camera at Nanwalek to help pilots better assess weather and airport conditions. The installation is slated to be complete in June 2013. The State of Alaska has plans to permanently close the Nanwalek Airport and to build a new airport to serve the communities of Nanwalek and neighboring Port Graham. Officials are still in the stages of acquiring land and right-of-way for the new site, and there is no definitive date that airport construction will commence.
