The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
During landing, N181CS, a Dehavilland twin otter, DHC-6-200, s/n 181, departed the runway surface at approximately 30 degrees to the right of the runway centerline. Ground scarring indicated that the tail drug approximately 30 feet prior impacting the trees. The right wing impacted the trees causing the aircraft to rotate clockwise and slide to a stop with the left wing and engine and wedged between trees.
I/a/w order 8900.1 vol.7, ch.1, sec.2 dated 01/27/2012. This airworthiness portion of this accident was transferred on 09/08/2015. It was initially investigated by gso pmi richard canovai. Mr. Canovai traveled to the accident site on 09/07/2015 and accumulated data including a pilot statement that can be veiwed in the brief explanation section of this report.
The surrounding area and final placement of the aircraft at the crash site validated the description by the flight crew. The aircraft departed to the right of the runway heading by about 50 to 80 feet and contacted trees. The fuselage remained relatively intact. The right wing was first to contact the trees and the force of contact rotated the aircraft approximately 90 degrees to the flight path. The left wing then entered between two trees without much contact. The force of contact to the right wing severed the right wing from the fuselage and stayed beside the fuselage when it came to rest, severed the engine from the wing and the right propeller from the engine. These components fell to the ground in close proximity as well. Contact with trees also damaged the right side of the cockpit area, injuring the first officer s legs. The debris field was contained within a 100 foot radius of the aircraft. This aircraft crash landed upon a return flight to home base of oonc, a small airport north of rdu airport. This aircraft underwent maintenance on 08/12/2015 pertaining to the right propeller model 4AFR34C764-D, s/n 130882. This propeller was installed on the right engine by rampart personnel after an overhaul by piedmont propulsion systems located in kernersville, NC. Entries in the aircraft maintenance log on 09/04/2015 indicate a test flight was conducted after the installation with no discrepancies noted. The next mission for the aircraft required th
