Accident Details
Probable Cause and Findings
The failure of company maintenance personnel to ensure that the airplane's nose baggage door latching mechanism was properly configured and maintained, resulting in an inadvertent opening of the nose baggage door in flight. Contributing to the accident were the lack of information and guidance available to the operator and pilot regarding procedures to follow should a baggage door open in flight and an inadvertent aerodynamic stall.

HISTORY OF FLIGHT
On January 5, 2008, about 1343 Alaska standard time, a twin-engine Piper PA-31-350 airplane, N509FN, received substantial damage when it collided with ocean water following a loss of control shortly after takeoff from Runway 36 at the Kodiak Airport, Kodiak, Alaska. The airplane was being operated by Servant Air, Inc., Kodiak, as a visual flight rules (VFR) on-demand charter flight under the provisions of Title 14 Code of Federal Regulations (CFR) Part 135, when the accident occurred. Of the 10 people aboard, the airline transport pilot and 5 passengers died at the scene, 3 passengers sustained serious injuries, and 1 passenger sustained minor injuries. Visual meteorological conditions prevailed, and company flight following procedures were in effect. The flight was en route to Homer, Alaska.
During an initial hospital room interview with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on January 5, about 2200, a passenger related that the purpose of the flight was to transport a group of commercial fishermen from Kodiak to Homer for Russian Christmas. He added that many of the passengers were family members that lived in the same community near Homer.
The passenger stated that he was seated in the third row on the right side of the airplane. He said that shortly after becoming airborne, he saw the airplane's nose baggage door open slightly, which he said initially startled the pilot. He said that while the airplane was still over the departure end of Runway 36, the pilot initiated a shallow right turn, presumably to return to the airport. He said that as soon as the pilot started the right turn, the baggage door swung open to the full open position, and it remained in that position. The passenger said that as the airplane continued the right turn, it rolled sharply to the right, and began a rapid, nose and right wing low descent. It collided with the water adjacent to the departure end of Runway 36. The passenger said that during the collision the fuselage fragmented, and the airplane sank shortly after impact. He said that he was able to free himself from the sinking wreckage by swimming though a large void in the airplane's fuselage.
According to the contract Air Traffic Control Tower (ATCT) specialist that was on duty at the time of the accident, the accident airplane departed from runway 36, and became airborne about midway along the 5,013-foot long runway. The ATCT specialist said that as the airplane continued to climb approaching the departure end of the runway, the pilot calmly stated that he needed to return to the airport, but gave no reason for his need to return. The ATCT specialist reported that as the airplane began a right turn, it began a steep roll to the right, and descended nose-low into the water. He said that immediately after witnessing the accident, he alerted airport fire rescue crew of the accident, and contacted the U.S. Coast Guard's Air Station Kodiak, which is located adjacent to the Kodiak airport.
The ATCT specialist noted that just after the accident, another Kodiak-based operator in a float-equipped de Havilland DHC-2 Beaver airplane contacted him on the tower radio frequency and said, in part: "[Kodiak] tower, Beaver five forty five's by the Crash Harbor, um can I help there?" The ATCT specialist responded by saying: "Beaver five forty five, yeah, you may be able to uh, you may be the first one that can get to those people that are in the water, they are right off the approach end of runway one eight, just off Buskin Beach, and uh you can transition into the airspace at your discretion." The ATCT specialist said that the pilot of the float-equipped de Havilland DHC-2 went directly to the accident site, then landed near the partially submerged wreckage.
During an interview with the NTSB IIC, on January 8, the pilot of the de Havilland DHC-2 Beaver airplane reported that at the time of the accident he was doing a postmaintenance engine run following a 100-hour inspection of his airplane. He said that while parked in a bay locally known as "Crash Harbor" adjacent to the Kodiak Airport, he initially overheard the radio conversation between the accident pilot and ATCT specialist, followed by the conversations between the ATCT specialist and the fire rescue crews, so he offered his assistance.
The pilot said that once he found the partially submerged wreckage, he landed, and then taxied close as he could to the sinking wreckage. He said he discovered two passengers swimming in the water next to the submerged wreckage, and two other passengers clinging to the airplane's exposed vertical stabilizer. He said that wind conditions at the time of the rescue made it very difficult to maneuver his airplane next to the wreckage. Once he had the four severely hypothermic passengers aboard, he departed to the north, and flew directly to the Kodiak boat harbor where an ambulance was waiting. The pilot noted that when he departed the accident site, no other passengers were visible on the surface of the water.
Pilot Preflight
During an interview with the NTSB IIC on January 8, an employee of Servant Air reported that the accident pilot loaded the airplane himself, while his passengers waited in the operator's lounge. The employee noted that he watched the pilot load various items into the forward baggage area, closed and latched the baggage door, then continued loading the remaining items in the aft baggage area, and wing lockers. He said that when the pilot was done loading the airplane, he saw him do a "walk around" the entire airplane. He said that when the pilot approached the forward baggage area, the pilot slide his open left hand across the closed door, then while making a loose fist, he lightly tapped the door, just above the door's handle and lock assembly, then continued around the airplane's right wing.
