Accident Details
Probable Cause and Findings
The non-instrument rated pilot's loss of control at night in instrument flight conditions due to spatial disorientation. A factor was the pilot's in-flight decision not to inform the controller that he was not instrument rated.

HISTORY OF FLIGHT
On August 17, 2007, at 2021 eastern daylight time, a Cirrus SR20, N869CD registered to a private owner, operating as a 14 CFR Part 91 personal flight deployed the Cirrus Airframe Parachute System (CAPS) after encountering instrument flight conditions (IFR) while descending to land at Nantucket Memorial Airport, Nantucket, Massachusetts. Instrument meteorological conditions prevailed at the time of the accident. No flight plan was filed however a full weather briefing was obtained before departing on the visual flight rules flight. The airplane received substantial damage. The non-instrument rated private pilot received serious injuries and one passenger received minor injuries. The flight originated from Westchester County Airport, White Plains, New York, on August 17, 2007, at 1901.
The Nantucket Tower controller stated the pilot established initial radio contact at 2010. The controller informed the pilot to continue for runway 24 and pointed out traffic. The pilot reported at 2012 that he had the traffic in sight. At 2013, the controller received a PIREP of a " low layer forming above the approach to runway 24." The controller advised the pilot at 2014 that the airport was going IFR, and switched the pilot to Cape Approach. The pilot informed the controller that he was capable of executing the instrument landing system (ILS) approach.
Review of transcripts between the pilot and Cape Approach revealed the pilot made initial radio contact at 2015, and requested the ILS runway 24 approach at Nantucket. Cape Approach asked the pilot for his current heading and the pilot replied 150. The controller informed the pilot to continue on the heading and expect a left downwind for the ILS approach. The pilot asked the controller if he wanted him to climb, and the controller suggested 2,000 feet, and the pilot acknowledged the altitude.
The controller stated at 2016: 43, "November nine charlie delta confirm that you are IFR equipped and qualified." The pilot replied, " Nine Charlie delta we are uh IFR qualified." At 2016: 50, the controller instructed the pilot to climb and maintain 2,000 feet and to turn left heading 090. The pilot replied, "Nine Charlie delta two thousand turning right two nine zero." The controller replied at 2017:03, "November nine Charlie delta roger you're cleared to Nantucket via heading uh zero seven zero climb and maintain two thousand." The pilot replied, "Nine Charlie delta right uh zero seven zero at two thousand." The controller replied at 2017:54, "November nine Charlie delta turn left heading zero six zero expect the ILS approach runway two four advise with new ATIS kilo." The pilot replied, "Nine charlie delta turning right to zero six zero we will pick up kilo." The controller stated at 2018:06, "Nine charlie delta that's not a right turn sir should be a left turn left turn heading uh zero six zero looks like you went right on the last turn so just turn left a gradual left turn to zero six zero." The pilot replied, nine charlie delta a gradual left turn to zero six zero. At 2019:37 the controller asked the pilot to say his type of aircraft. The pilot replied at 2019:39, "Cirrus I had to pull the parachute." The controller replied, November nine charlie delta are you able to make it to the airport sir. The pilot stated, "No the parachute on the plane its going to come down." The controller replied at 2020:02, "November nine charlie delta roger low altitude alert check your altitude immediately and uh advise if you need any further assistance it appears that you are over land at this time." There were no other radio transmissions between the pilot and the controller.
The pilot told the NTSB investigator during an interview that he informed the controller that he was instrument-qualified because he was getting concerned. His wife was six months pregnant and he feared they would end up in the water. The pilot stated he was struggling to keep the airplane level; he was in instrument conditions in a black hole with out a visible horizon or ambient light. The pilot further stated, "I became spatially disoriented and pulled the chute." When the pilot was asked if there was anything mechanically wrong with the airplane or the flight instruments, the pilot stated no.
PERSONNEL INFORMATION

WRECKAGE AND IMPACT INFORMATION
The wreckage was located in the vicinity of a United States Coast Guard loran signal tower adjacent to a residence in Siassconset Massachusetts, and 5 miles southeast of the Nantucket Memorial Airport. The airplane collided with a guy wire supporting the 650-foot tall loran signal tower on a heading of 040-degrees magnetic. Two pieces of parachute material were observed entangled on one of the loran guy wires. The airplane came to rest on a heading of 323-degrees magnetic.
The upper and lower engine cowling was partially separated from the airframe. The engine assembly was partially separated from the firewall and displaced to the left about 20-degrees. Both upper engine mount welds separated between the firewall bolt attachment points and the first welded joint along the steel tubing. The lower two engine mounts remained attached to the firewall. The lower left section of the firewall was displaced aft, and the lower right side of the firewall was displaced in the forward direction and to the left. All engine accessories remained attached to the engine except for the starter, No. 2 alternator and right magneto. The fuel supply line to the fuel distribution manifold was disconnected and fuel was present in the fuel line. The nose wheel assembly separated from the nose landing gear strut at the fishmouth. The nose wheel was located in a 5-inch hole 7-feet in front of the wreckage.
The engine was equipped with an engine monitoring system. The primary flight display (PFD) and the internal compact flash memory module from the multi-function display (MFD) were removed and sent to the NTSB Vehicle Recorders Laboratory for further examination. Examination revealed the PFD and the MFD memory card were not damaged. A binary copy of the memory card was made in the NTSB laboratory, and the copy was read out using a bench MFD. The PFD was connected to a bench MFD and downloaded. The raw PFD download file was sent to the manufacturer for decoding into ASCII text. The decoded file was so...
