This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

On September 1, 2012, about 1100 eastern daylight time, a Cirrus SR22, N221DV, was substantially damaged when it impacted trees during a landing attempt at Falmouth Airpark (5B6), Falmouth, Massachusetts. The flight instructor was fatally injured, and the student pilot and passenger were seriously injured. Visual meteorological conditions prevailed, and no flight plan had been filed for the flight from Tweed-New Haven Airport (NVN), New Haven, Connecticut. The instructional flight was conducted under the provisions of 14 Code of Federal Regulations Part 91.

While the student pilot and a passenger survived the accident, due to the extent of their injuries, they could not be interviewed. According to several witnesses, the airplane completed a right downwind for runway 7. The final approach over trees was described as "unstable, with rocking wings," and one witness asked another if he thought the airplane was going to go around.

Exact recollections differed, but in general, witnesses recalled that as the airplane neared the runway, there were some additions and reductions in power. The airplane started veering to the left, there was an addition of power, and the left wing almost hit the ground. The airplane then touched down in the grass to the left of the runway, went through the last section of a wooden fence, entered some woods and burst into flames.

An examination of the accident site revealed skid marks in the grass to the left of the runway, with the mark attributed to the position of the left main landing gear appearing first. The marks commenced about 80 feet left of the runway, 300 feet from the approach end, and headed about 030 degrees magnetic, toward the woods. The airplane's left wing was found separated from the rest of the airplane at the first large tree in the woods, and the airplane came to rest about 80 feet beyond that tree, upside down.

The airplane was mostly consumed by fire. Evidence of all flight control surfaces was found at the scene, and continuity was confirmed from the cockpit along the lengths of all flight control cables. The flap actuator indicated that the flaps were at 50 percent.

The engine exhibited severe fire damage, and the crankshaft could not be rotated. Two of the three metal propeller blades exhibited torsional bending, and one blade could be rotated in the hub. The third propeller blade was straight, but had cut into the propeller spinner toward the direction of rotation. The spinner also had a large concave indentation in it, similar in shape to a tree trunk.

Data chips were not recovered from the primary flight display and multifunction display, which were charred and jelled together. The tail-mounted remote data module was recovered and forwarded to the NTSB Recorders Laboratory; however, the unit was thermally damaged internally and no data extraction was possible. The unit's memory chip was then extracted and attempts to restore it are ongoing.
