HISTORY OF FLIGHTOn May 24, 2013, at 1710 eastern daylight time, a Piper PA34-200T, N31743, operating as Angel Flight 743, was destroyed during an in-flight breakup near Johnstown, New York. The commercial pilot and two passengers were fatally injured. Instrument meteorological conditions prevailed, and an instrument flight rules flight plan was filed for the personal flight, which departed Laurence G. Hanscom Field Airport (BED), Bedford, Massachusetts, and was destined for Griffiss International Airport (RME), Rome, New York. The flight was operated under the provisions of Title 14 Code of Federal Regulations Part 91.
The purpose of the volunteer medical transport flight was to return the patient and his spouse from the Boston, Massachusetts, area to their home in New York. The flight departed BED at 1603, and the pilot contacted air traffic control (ATC). Radar contact was established at 1604, and the flight was incrementally cleared to a cruise altitude of 8,000 feet msl.
At 1630, ATC advised the pilot of an area of moderate to occasionally heavy precipitation along the airplane's route of flight. The pilot indicated that he "[had] the weather upload" and was aware of the precipitation. ATC instructed the pilot to advise if he required a deviation around the weather, and the pilot acknowledged. About 15 minutes later, the pilot requested and was issued a 20-degree left deviation for precipitation.
At 1643, ATC asked the pilot if he was able to turn back on course. The pilot requested to fly to the very high frequency omni-directional range (VOR) at Albany International Airport (ALB), Albany, New York, and then stated that he could resume the planned course. After passing ALB, the pilot was cleared direct to ROOMS intersection. The pilot acknowledged, and established the airplane on an approximate 290-degree track toward the intersection.
At 1703, the pilot was issued a frequency change to the Syracuse, New York approach control facility. The pilot subsequently contacted ATC on the new frequency and advised that he had the current weather information at RME. The controller advised the pilot of areas of light to moderate precipitation along the airplane's route and suggested a deviation to avoid the precipitation; however, the pilot elected to stay on course to ROOMS, then planned to turn left to fly direct to the Utica VOR in Utica, New York, before proceeding to RME.
Around 1708, ATC noted that the airplane had begun a right turn to the north from its established track toward ROOMS. When ATC queried the pilot about the deviation, he replied, "Yeah I turned the wrong way here I'm sorry I thought I loaded the…approach correctly but I didn't it turned me toward the wrong [unintelligible]…." ATC provided the pilot with a heading of 280 degrees to return on course, which the pilot acknowledged by replying, "two eight zero." About this time, the airplane initiated a descending left turn, and radar contact was lost about one minute later.
Radar data showed the airplane established on a track of about 290 degrees toward ROOMS intersection at an altitude of 8,300 feet. About 1707, approximately five miles southeast of ROOMS, the airplane began a gradual right turn to the north. At 1708, the airplane turned north-northeast and continued on that track for about one minute before beginning a descending left turn. The last three recorded radar targets, between 21:09:01 and 21:09:19, showed the airplane at altitudes of 8,200 feet, 7,800 feet, and 6,700 feet respectively. The last recorded radar return placed the airplane about 1,500 feet west of the main wreckage.
A witness near the accident site reported that she observed the airplane in a steep bank at an altitude "around 1,000 feet" as it flew southwest in the direction of the Garoga Reservoir, located about 7 miles west-northwest of Johnstown, New York. She reported that the left wing was missing from the airplane. As it disappeared from her view behind a row of trees, she heard an "explosion," then ran across the road to render assistance to any victims.
Another witness, who was canoeing with a friend on the reservoir at the time of the accident, stated that he heard a "loud whining noise like an engine at full throttle." As he watched the airplane descend and grow closer, he heard a "loud bang" and subsequently observed it break apart. He stated that he saw an engine falling, and that it impacted land. "Bolts and other small parts" fell around the canoe, and the men rowed away to avoid being hit. The witness saw the fuselage descending, and heard it impact the water, but could not see where it impacted.
A third witness near the accident site described hearing the airplane circle the area "from the south to the east to the north and then to the west." He stated that the engines sounded as though they were "revving" up and down. He then heard the sound of an explosion, and observed parts of the airplane falling to the ground. PERSONNEL INFORMATIONThe pilot, age 70, held a commercial pilot certificate with ratings for airplane multiengine land and instrument airplane, and a private pilot certificate with ratings for airplane single engine land and sea. His most recent Federal Aviation Administration third class medical certificate was issued on May 16, 2013.
Review of the pilot's personal flight logs indicated that he had completed a 1.2-hour combined flight review and instrument proficiency check in November 2012. In the six months preceding the accident flight, the pilot logged about 53 total hours of flight time, of which about 9 hours were in actual instrument meteorological conditions (IMC). All of the flight time in actual IMC was logged in the 30 days prior to the accident flight. At the time of the accident, the pilot had logged about 1,746 total hours of flight time, of which over 1,000 hours were in the accident airplane make and model. AIRCRAFT INFORMATIONThe airplane was manufactured in 1978 and registered to the pilot in 1998. It was equipped with two Continental TSIO-360 turbocharged, reciprocating engines, each of which produced 200 horsepower. Review of maintenance logs indicated that the most recent annual inspection was completed on March 3, 2013 at a total aircraft time of 3,505.4 hours. At the time of the accident, the airplane had accumulated a total time of 3550.6 hours. METEOROLOGICAL INFORMATIONThe 1653 weather observation at RME, located about 40 miles northwest of the accident site, included winds from 330 degrees magnetic at 8 knots, 10 statute miles visibility in light rain, broken cloud layers at 2,300 and 2,800 feet, overcast clouds at 3,700 feet, temperature 7 degrees C, dew point 4 degrees C, and an altimeter setting of 30.06 inches of mercury.
Schenectady County Airport (SCH), Schenectady, New York, was located about 27 miles to the east-southeast of the accident site. A human-augmented report issued at 1645 included wind from 320 degrees at 8 knots gusting to 16 knots, 7 statute miles visibility, overcast clouds at 2,600 feet, temperature 8 degrees C, dew point 7 degrees C, and an altimeter setting of 29.96 inches of mercury.
ALB was located approximately 36 miles to the east-southeast of the accident site. The 1651 observation included wind from 310 degrees at 9 knots, 1.5 statute miles visibility, runway 1 visual range variable between 5,000 and 6,000 feet, rain, mist, and overcast clouds at 800 feet, variable between 500 and 1,100 feet.
An upper air sounding retrieved from a rawinsode launch at 2000 in Albany, New York indicated that the majority of the troposphere was stable or conditionally unstable. A temperature inversion was noted between 5,700 and 7,400 feet. The freezing level was approximately 4,300 feet, with the potential for moderate icing near 10,000 and 14,000 feet. A wind profile indicated a generally northerly wind from 1,000 feet to 7,500 feet, with magnitudes between 12 and 24 knots, and a potential for significant turbulence near 7,500 feet.
Weather radar imagery from Albany, New York, about the time of the accident, depicted light values of reflectivity over much of the area surrounding the accident site with moderate values immediately to the west and southwest of the accident site. Imagery identified the presence of "big drops" of rain in the vicinity of the accident site, with wet snow and snow pellets to the west of the accident site, indicative of melting snow in the area.
Airmen's Meteorological Information (AIRMET) advisories, issued at 1645 for IMC and mountain obscuration, moderate turbulence below 8,000 feet, and moderate icing between the freezing level and 22,000 feet, were valid for the region surrounding the accident site.
The Area Forecast for northeastern New York issued at 1331 and valid for the accident time predicted overcast cloud ceilings at 1,000 to 2,000 feet with cloud tops to 18,000 feet, surface visibility 3-5 miles, light rain, and mist.
There were no records of the pilot obtaining a weather briefing from Lockheed Martin Flight Services, DTC DUAT, or CSC DUATs weather information services. Review of data provided by a third-party internet flight planning and weather briefing service showed that the pilot filed the flight plan for the accident flight about 1020 the morning of the accident. The pilot also accessed a weather radar summary map for the route of the accident flight at this time. AIRPORT INFORMATIONThe airplane was manufactured in 1978 and registered to the pilot in 1998.
