NTSB summary

HISTORY OF FLIGHT On June 18, 2008, at 1001 eastern daylight time, a DeHavilland DHC-6, N656WA, operated by Wiggins Airways, was substantially damaged when it impacted terrain during a takeoff attempt from Barnstable Municipal Airport (HYA), Hyannis, Massachusetts. The certificated airline transport pilot was fatally injured. Visual meteorological conditions prevailed, and an instrument flight rules flight plan was filed for the flight, destined for Nantucket Memorial Airport (ACK), Nantucket, Massachusetts. The cargo flight was conducted under the provisions of 14 Code of Federal Regulations (CFR) Part 135. According to the operator, the airline was based in Manchester, New Hampshire, while the accident airplane and pilot were based at Hyannis. The accident flight was scheduled to depart Hyannis at 0900, but was often late in departing due to the cargo's delayed arrival to the airport. About 0800, the pilot contacted the operator via telephone in order to provide the flight's fuel and alternate destination information. At 0956, the pilot contacted air traffic control and requested clearance to taxi for departure, and was later cleared to take off from runway 24 at 1000. A witness located just outside the airport perimeter fence, and near the arrival end of runway 24, observed the airplane as it taxied. According to the witness, he found it strange that the airplane did not stop and "rev up" its engines as he thought airplanes normally did, but instead taxied on the taxiway parallel to the runway and then made a 180-degree turn onto the runway without stopping. The airplane

Probable cause

The pilot's failure to remove the flight control lock prior to takeoff. Contributing to the accident was the Federal Aviation Administration's failure to issue an airworthiness directive making the manufacturer's previously-issued flight control lock service bulletins mandatory.
