A FACTOR RELATED TO THE ACCIDENT WAS: INADEQUATE VISUAL LOOKOUT BY THE PILOT OF THE JUMP AIRCRAFT. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, cruise - normal - light condition - sunglare - identification of aircraft on radar - not attained, atc personnel(dep/apch) (cause) - traffic advisory - not issued, atc personnel(dep/apch) (cause) - radar traffic information service - not used, pilot in command - visual lookout - inadequate, pilot of other aircraft (contributing factor) - object - other person - Airframe/component/system failure/malfunction, cruise - normal - vertical stabilizer surface - foreign object damage - vertical stabilizer surface - separation - Loss of control - in flight, cruise - normal - aircraft control - not possible - In flight collision with terrain/water, descent - uncontrolled ## Analysis A PIPER PA-28, N3011F, WAS IN VFR CRUISE FLIGHT HEADING EASTBOUND AT ABOUT 5700' MSL, AS A CESSNA 210 (PARACHUTE JUMP PLANE) HAD JUST COMPLETED A CLEARING TURN TO A WESTBOUND HEADING, INTO THE SUN, AT 7300' MSL. A PARACHUTIST JUMPED FROM THE JUMP PLANE & STRUCK THE VERTICAL STABILIZER OF THE PA-28 AFTER A FEW SECONDS OF FREE FALL. CONTROL OF THE PA-28 WAS LOST, & IT CRASHED IN AN UNCONTROLLED DESCENT. THE JUMP PLANE WAS IN RADAR & RADIO COMMUNICATION WITH AIR TRAFFIC CONTROL (ATC) IN ORDER TO RECEIVE TRAFFIC ADVISORIES PER THE FAA ATC CONTROLLER'S HANDBOOK. THE PA-28 WAS RECORDED ON RADAR. NO ADVISORIES WERE ISSUED TO THE JUMP PLANE AFTER THE PILOT CALLED '1 MINUTE PRIOR TO JUMP.' TESTS SHOWED THAT ONE TRANSCEIVER IN THE PA-28 WAS TUNED TO 120.30 MHZ; A WARNING FOR PARACHUTE JUMPING WAS GIVEN OVER THIS FREQUENCY. A 1/8' PARACHUTE SYMBOL (COLORED BLUE) WAS DEPICTED ON THE SECTIONAL CHART AND WAS SUPERIMPOSED OVER A RIVER (ALSO COLORED BLUE). THE CONTROLLER WAS RECEIVING ON-THE-JOB TRAINING FROM A FULL PERFORMANCE CONTROLLER. ## Factual narrative HISTORY OF FLIGHT On November 21, 1993, about 1356 hours eastern standard time, a Piper PA-28-161, N3011F, collided with a free-falling parachutist while in cruise flight over the Northampton Airport, Northampton, Massachusetts. The airplane subsequently impacted terrain during an uncontrolled descent and was destroyed. The certificated private pilot and the three passengers were fatally injured, and the parachutist received serious injuries. The airplane was operated by Red Hook Air Service, Red Hook, New York. The personal flight originated in Red Hook and was destined for Bedford, Massachusetts. Visual meteorological conditions prevailed and a flight plan was not filed for the flight. According to the operator, the accident airplane departed the Red Hook Sky Park about 1300 hours for a round-trip, cross country flight. The purpose of the flight was to return the son of the pilot and the son's acquaintance to the Boston area after a weekend at the pilot's home in Rhinebeck, New York. An acquaintance of the pilot was also on board and intended to return to Rhinebeck with the pilot. No record of communications between the pilot of the accident airplane and any FAA facility were found. As the flight of the accident airplane proceeded eastbound in cruise flight toward Boston, another airplane, N50442, a Cessna 210, departed from the Northampton Airport. The airplane was a "jumper" airplane with five sport parachutists and the pilot on board. According to the operator of the jumper airplane, the purpose of the flight was to drop five parachutists in free fall over the Northampton Airport. Four of the five parachutist on board were to jump as two pairs of "tandem" jumpers. The solo jumper was not attached to anyone and was designated as the "spotter"; he was to guide the pilot over the jump zone and jump out of the airplane first. The flight was the fifth jumper flight of the day. According to FAA air traffic control (ATC) voice recordings, the pilot of the jumper airplane contacted Bradley Approach Control at 1347:21 hours immediately after departing from the Northampton Airport. The pilot reported that he was at 1,800 feet and climbing to 8,000 feet "... with jumpers." The controller, having already issued a discrete transponder code for the previous four jumper flights, provided a traffic advisory and requested that the jumper airplane "... report one minute prior ..." to releasing the jumpers. According to the jumper airplane pilot: I climbed and circled (to clear for traffic) for about eight minutes. My job is to put the jump plane over the 'spot'. It was pretty windy at altitude and I would estimate our ground speed to be about 45 knots when we turned onto the course for the jump run. I turned from 90 degrees onto the jump run as a final clearing turn. I did not see any other traffic. I contacted Bradley and gave them a 'one minute to jump' warning. The jumper airplane pilot also stated that he transmitted the same warning on the Northampton Airport common traffic advisory frequency (CTAF). According to ATC voice recordings, the jumper airplane pilot issued a "one minute prior" warning to Bradley Approach Control at 1355:32 hours. The controller then made the following transmission on the Approach Control frequency: "Attention all aircraft one minute to parachute jumping vicinity of Northampton Airport surface to eight thousand feet." No advisories were issued by the controller to the jumper airplane pilot concerning the accident airplane. Also, no communications were made by the accident airplane with either Bradley Approach Control or the Northampton CTAF. According to the solo parachutist on the jump airplane, he was the first to jump out of the jumper airplane. He stated that he received the "door open" sign from the pilot, opened the door, and looked out to "fine tune" the pilot's course over the jump zone. He stated that he did not observe any other air traffic in the area as he was looking out the door. He then jumped out of the airplane. About five to six seconds later, he observed "... an airplane coming right at me. I was coming from above it - angling down towards it." He stated that he thought he would miss the airplane, but "... hit the tail ..." instead. He then deployed his parachute and floated toward the drop zone. He stated that as he was floating, he observed the accident airplane "... about 200 feet above the ground, going in totally out of control." A ground witness located at the Northampton Airport reported that as he was observing the jumper airplane, he noticed the accident airplane heading in the "... totally opposite direction ..." of the jump airplane. He observed the first parachutist jumping out of the jumper airplane and striking the rudder of the accident airplane. He observed "... a rudder piece fall off ..." and then saw sparks. He stated that it was "... only a few seconds from the time the jumper came out to the time he hit the Piper." The ground witness also stated: The Piper stayed level for a second or two [after it was hit], then it banked to the right, then to the left, then to the right again. It kept on spiralling down to the right in a really nose down attitude. It looked almost inverted as it got closer. The tailcone looked intact, but there was no rudder. There was no fire or smoke as it descended. I saw it until it disappeared behind trees. At 1356:43 hours, a sound similar to the tone of an emergency locator transmitter (ELT) was recorded on the ATC voice recording. At 1357:04 hours, the jumper airplane pilot transmitted "jumpers away" to Bradley Approach Control. At 1357:08 hours, Bradley Approach Control issued a traffic advisory to the jump airplane, stating that traffic was "one mile east of your position altitude indicating two thousand six hundred." At 1358:29 hours, the jumper airplane pilot issued a "MAYDAY" to Bradley Approach control and reported that he had just witnessed an airplane accident. The accident occurred during the hours of daylight at 42 degrees 19.34 minutes North, and 072 degrees 35.50 minutes West. PERSONNEL INFORMATION The pilot of the accident airplane, age 49, was issued a private pilot certificate with a rating for airplane single engine land on February 2, 1992. According to his personal flight logbook, he had accumulated a total of 177 hours of flight time, all in type. He received an FAA third class medical certificate on July 28, 1993. The pilot of the jumper airplane, age 28, was a certificated airplane transport pilot and certified flight instructor. He reported that he had logged over 3,000 hours of flight time. He was employed by the operator of the jumper airplane for six months preceding the accident. The solo parachutist who struck the tail of the accident airplane, age 51, held an "A" sport parachute rating. He stated that he had accumulated about 37 sport parachute jumps during the preceding two years. According to the FAA, the ATC specialist who was providing advisories to the jumper airplane was receiving on-the-job training at the time of the accident. A full performance ATC specialist was designated as his instructor at the time of the accident. METEOROLOGICAL INFORMATION The reported surface weather observation at Bradley International Airport, located about 24 nautical miles south of the accident site, three minutes prior to the accident was: "sky clear, visibility 20 miles, temperature 46 degrees F, dewpoint 19 degrees F, wind 220 degrees at 14 knots, altimeter 30.23 inches Hg." At the time of the accident, the true bearing to the sun at 7,000 feet mean sea level (msl) was 214.9 degrees. The altitude of the sun was 21.3 degrees of declination. ## Aircraft - Registration: [N3011F](https://openairdocs.org/deregistered/N3011F-1994-05-02), registration cancelled 1994-05-02, S/N 287916211 (OpenAirDocs) - Reported make and model: PIPER PA-28-161 - Registry model: [Piper PA-28-161](https://openairdocs.org/model/piper-pa-28-161) (registry code 7102803) (OpenAirDocs) - Category: Airplane - Serial number: 28-7916211 - Airframe hours: 4212 - Engines: Lycoming O-320-D3G 160 horsepower reciprocating - Damage: Destroyed - Flight: Personal, Part 91 - Operator: Drobot, George Jr., doing business as Red Hook Air Service - Registered owner: Drobot, George Jr. - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, August 25, 1993, 68 hours before - Departed: 46N, RED HOOK, NY - Destination: BED, BEDFORD, MA ## Flight crew As NTSB recorded them.
