Raneille, WV, USA
N8923Y
PIPER PA-30
The pilot departed on the first of two flights toward his home airport during day visual meteorological conditions. He stopped en route about 4 hours later, then departed shortly before midnight (accident time zone) toward his final destination in night visual meteorological conditions. About 3 hours later, the airplane impacted trees and rising terrain during night marginal visual meteorological conditions. Radar data indicated that during the last 3 minutes of flight, the airplane flew a serpentine course at varying low level altitudes. On the morning before the accident, the pilot obtained a computer-based weather briefing, which included deteriorating weather conditions along the route, and instrument meteorological conditions beyond the accident site. The pilot subsequently received about 1 hour 30 minutes of dual instruction in the newly-purchased airplane, and following that, the instructor attempted to persuade him to spend the night. The pilot responded that he didn't want to wait because of the deteriorating weather along the latter part of his route, but agreed to stop overnight along the way. The pilot later told another person that he would continue to his destination. The time from when the pilot obtained a weather briefing until the accident was about 16 hours; however, it is unknown if or when the pilot may have rested, how fatigued he may have been, or if it affected the outcome. Although the pilot held an instrument rating, he had not flown in actual instrument conditions for about 18 years prior to the accident. Post-accident examination of the airplane's airframe, flight controls, propellers, engine assemblies and accessories revealed no mechanical anomalies, and damage to the propellers indicated that both engines were under power at impact. The serpentine flight path and the wreckage path indicated the likelihood that the airplane was in controlled flight when it impacted the trees.
HISTORY OF FLIGHT On November 23, 2009, at 0234 eastern standard time (EST), a Piper PA-30, N8923Y, registered to and operated by a private owner, as a 14 Code of Federal Regulations Part 91 personal flight, was substantially damaged when it collided with trees while descending in mountainous terrain in the vicinity of Rainelle, West Virginia. Night marginal visual meteorological conditions prevailed in the vicinity of the accident site, and no flight plan was filed. The certificated commercial pilot was killed. The flight departed, Kennett Memorial Airport (TKX), Kennett, Missouri, for Stafford Regional Airport (RMN), Stafford, Virginia, at 1727 Central Standard Time (CST). The airplane did not arrive at its destination and was reported as missing to the Air Force Rescue Coordination Center on November 28, 2009. The airplane wreckage was located by the West Virginia Civil Air Patrol on December 1, 2009. Review of Fort Worth Center radar data confirmed that the airplane initially departed Dalhart Municipal Airport (DHT), Dalhart, Texas DHT at 1727 CST. Radar data obtained from Memphis Center revealed the airplane landed at TKX at 2118 CST. After departing TKX, the airplane was observed on radar at 4,800 feet, northeast of the airport at 2248 CST. The airplane was last observed by Indianapolis Center in the vicinity of the accident site. Radar data also indicated that during the last 3 minutes of contact, the airplane flew a serpentine course, and that it climbed from 3,300 feet to 3,900 feet, before it descended to 3,300 feet and contact was lost. PERSONNEL INFORMATION The pilot, age 52, held a commercial pilot certificate issued on April 8, 2004, with ratings for airplane single-engine land, airplane multiengine land, helicopter, and instrument airplane. In addition, the pilot held a second-class medical certificate, issued on October 2, 2009, with no restrictions. The pilot indicated on his application for the medical certificate that he had 1,575 total flight hours. According to the previous owner, who sold the airplane to the accident pilot on August 28, 2009, the pilot had accumulated 50 hours of multiengine time in Beech airplanes. The pilot did not have any flight time in the PA-30. The pilot obtained 1 hour 30 minutes of flight instruction from a certificated flight instructor (CFI) at DHT, before departing on the accident flight. The pilot’s logbooks were located at the crash site. The pilot indicated he had accumulated 1,672.9 total flight hours; of which, 1336.1 hours were in airplane single-engine land, and 61.0 hours in airplane multiengine land. The pilot flew 7.3 hours in the PA-30 after his "check out" on November 22 and 23, 2009. The pilot logged 215 hours of night flight, and his last recorded night flight before the accident was on October 18, 2009. The pilot logged 179.2 hours of actual instrument flight, and his last recorded instrument flight was on December 29, 1991. The pilot logged 268.5 total hours of helicopter rotorcraft. The pilot logged 24.5 hours in the last 90 days and 14.7 hours in the last 30 days; of which, 8.8 hours were in the PA-30, including the accident flight. The pilot’s last flight review was on November 15, 2009. AIRCRAFT INFORMATION The four-seat, multiengine, low-wing monoplane, serial number 30-1996, was manufactured in 1969. It was powered by two Lycoming IO-320-C1A, 160-horsepower engines and equipped with Hartzell model HC-E2YL-2RBS constant-speed propellers. A review of the airframe maintenance records revealed the last annual inspection was performed on November 20, 2009. At the time of the inspection, the tachometer time on the left engine was 810.8 hours and the right engine tachometer was 1,668.64 hours. The left tachometer was destroyed. The right tachometer at the accident site indicated 1,677.54 hours. The airplane had flown 8.75 hours since the last annual inspection. The total airframe hours at the time of the accident were 8,566.15 hours. The left and right engines were overhauled on July 7, 1991. The left engine had accumulated 1,964.44 hours since overhaul, and the right engine had accumulated 1,945.58 hours since overhaul. All new cylinder assemblies were installed on both engines on November 12, 2008. The combustion air heater decay test was completed on April 3, 2008. The pitot static and transponder inspections were completed on March 21, 2008. The airplane was "topped off" with 61.7 gallons of 100 low lead fuel before the pilot departed TKX. METEOROLOGICAL INFORMATION At 0934 CST, the pilot obtained a full Direct Users Access Terminal System (DUATS) weather briefing. The briefing included a Terminal Area Forecast (TAF) for Charlottesville-Albemarle Airport (CHO), Charlottesville, Virginia, located along the approximate direct route of flight, and about 110 nautical miles east of the accident site. According to the TAF, at 0100 EST, the ceiling was expected to be 700 feet overcast, with visibility 2 miles in mist. At 0400 EST, the ceiling was expected to be 500 feet overcast, with visibility 1 mile in rain and mist. Weather along the pilot’s route of flight included visual meteorological conditions (VMC) until entering Kentucky and West Virginia, where the weather conditions changed to marginal VMC (MVMC) with low ceilings and rain showers. The closest weather reporting sites to the accident were Raleigh County Memorial Airport (BKW), Beckley, West Virginia, located 22 miles southwest of the accident site at an elevation of 2,504 feet mean sea level (msl) and Greenbrier Valley Airport (LWB), Lewisburg, West Virginia, located 24 miles southeast of the accident site at an elevation of 2,302 feet msl. Both airports reported MVFR conditions in light to moderate rain, with broken to overcast ceilings between 1,300 feet to 1,500 feet above ground level (agl). The BKW observation, at 0151, included winds from 120 degrees at 11 knots, gusting to 20 knots, visibility 4 miles, moderate rain and mist, ceiling broken at 4,900 feet agl, overcast at 6,000 feet, temperature 5 degrees Celsius, dew point temperature 4 degrees Celsius, and altimeter 30.15 inches of mercury. The remarks section indicated a peak winds of 29 knots within the hour, with .04 inches of rainfall. The next observation for BKW, at 0251, reported the rain ending at 0250 with a ceiling at 1,300 feet.

MEDICAL AND PATHOLOGICAL INFORMATION The Charleston West Virginia State Medical Examiner conducted a postmortem examination of the commercial pilot on December 2, 2009. The cause of death was multiple injuries. The Forensic Toxicology Research Section, FAA, Oklahoma City, Oklahoma performed postmortem toxicology of specimens from the pilot. The specimens were not tested for carbon monoxide or cyanide. Ethanol, 19 (mg/dl, mg/hg) was detected in the muscle and putrefaction was noted as yes. No ethanol or drugs were detected in the liver. ADDITIONAL INFORMATION According to hotel records, the pilot checked into a hotel in Amarillo, Texas, on November 19, 2009, at 1620. He did not leave a wakeup call while staying at the hotel. The pilot checked out of the hotel on November 22, 2009, at 1234, drove to Amarillo International Airport AMA), Amarillo, Texas, and turned in his rental car. According to the CFI, he picked the pilot up at AMA and they flew in the CFI's airplane to DHT where he conducted flight training with the accident pilot in the PA-30. Upon completion of the instructional flight, the pilot stated that he wanted to depart for Virginia. The CFI suggested that he stay overnight, but the pilot responded that if he "didn't get started, that weather would be too bad in the eastern part of his trip." The pilot later advised the CFI that he'd land and remain overnight in Missouri, but then informed a mechanic that he would fly the entire trip that night.
The pilot's improper decision to attempt visual flight into deteriorating night weather conditions, and his subsequent controlled flight into terrain.
