# NTSB NYC02LA136: Stinson 108-2, N390C, Lincoln Park, NJ, July 10, 2002 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: July 10, 2002, 11:25 local (15:25 UTC) - Place: Lincoln Park, NJ - Coordinates: 40.947223, -74.313888 - Nearby events: https://openairdocs.org/map.md?lat=40.9472&lon=-74.3139&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report July 23, 2003 - Report: Approved by Office Director - Parties: FAA/FSDO - NTSB case key (mKey): 55181 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=NYC02LA136 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/55181/pdf - NTSB docket: https://data.ntsb.gov/Docket?ProjectID=55181 - Page: https://openairdocs.org/ntsb/NYC02LA136 ## Probable cause The pilot's failure to abort the takeoff when diminished performance was noted. A factor was carburetor icing, accumulated before the takeoff attempt. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, takeoff - weather condition - carburetor icing conditions (contributing factor) - Loss of control - in flight, takeoff - initial climb - lift-off - not maintained, pilot in command - directional control - not maintained, pilot in command - In flight collision with object, takeoff - initial climb - object - aircraft parked/standing - aborted takeoff - not performed, pilot in command (cause) - In flight collision with terrain/water, takeoff - initial climb - terrain condition - drop-off/descending embankment - terrain condition - roadway/highway ## Analysis The pilot conducted a preflight inspection, started the engine, and performed magneto and carburetor heat checks. He then taxied the airplane about 1,500 feet for takeoff, and had to wait, with the engine at idle, while four other airplanes landed, and the one in front of him took off. Prior to takeoff, the pilot selected takeoff flaps and takeoff trim. During the takeoff roll, the pilot felt the airplane was not accelerating normally, but attributed it to summer temperatures. About 1,000 feet down the runway, the airplane broke ground briefly, then settled back down and became airborne again in about 100 feet. After the pilot subsequently "got it off the ground," he felt that it was not accelerating normally, so he pushed the yoke forward and raised the flaps. The airplane drifted off the left side of the runway and settled into a parked airplane before continuing up an embankment, and coming to rest partially on a road. In a statement provided several months after the accident, the pilot stated that the engine "was not running" when it settled into the parked airplane. Post-accident examination of the airplane revealed no mechanical discrepancies which could have contributed to the accident. The fuel was checked, and found to be clear, blue in color, and absent of debris. A carburetor icing probability chart revealed that ambient conditions during the time of the accident could have resulted in moderate icing at cruise power or serious icing at glide power. According to a maintenance technician, the engine was susceptible to carburetor icing on the ground due to the position of the air intake manifold. After a ground run-up subsequent to the accident, the carburetor box was cold to the touch. ## Factual narrative On July 10, 2002, at 1125 eastern daylight time, a Stinson 108-2, N390C, was substantially damaged when it struck a parked, YAK-55 during an attempted takeoff from Lincoln Park Airport (N07), Lincoln Park, New Jersey. The certificated private pilot received minor injuries. Visual meteorological conditions prevailed at the time. No flight plan had been filed for the flight, between Lincoln Park and Warwick Municipal Airport (N72), Warwick, New York. The personal flight was conducted under 14 CFR Part 91. According to the pilot, he conducted a preflight inspection, started the engine, and performed magneto and carburetor heat checks. He then taxied the airplane about 1,500 feet, to the south end of the airport for a takeoff from runway 01. He was second in line to take off, but had to wait for "a considerable time" with the engine at idle while four other airplanes landed, and the one in front of him took off. Prior to takeoff attempt, the pilot selected takeoff flaps and takeoff trim. During the takeoff roll, the pilot felt the airplane was not accelerating normally, but attributed it to summer temperatures. About 1,000 feet down the runway, the airplane broke ground briefly, then settled back onto the runway, "which was not unusual in summer." The pilot then "got it off the ground" by pulling back on the yoke, but still felt the airplane was not accelerating normally, so he raised the flaps. The airplane drifted off the left side of the runway and settled into the Yak. The airplane then continued up an embankment, and came to rest partially on a road. In a written statement provided several months after the accident, the pilot amplified his original statement: "About 1,000 feet, I broke ground briefly...and I became airborne again in another 100 feet. I glanced at the airspeed indicator and saw that the speed was below stall with flaps, and pushed the yoke forward to reduce the angle of attack, and released the flaps to increase speed. I did not notice that the engine was not running." Post-accident examination of the airplane revealed no mechanical discrepancies which could have contributed to the accident. The fuel was checked, and found to be clear, blue in color, and absent of debris. A carburetor icing probability chart revealed that ambient conditions during the time of the accident could have resulted in moderate icing at cruise power or serious icing at glide power. The airplane was equipped with a Franklin 6A-4165 series engine. According to the certificated airframe and powerplants mechanic who maintained the airplane, the engine was particularly susceptible to carburetor icing on the ground due to the position of the air intake manifold. An engine runup was completed after the accident. Immediately afterwards, the carburetor box felt cold to the touch. ## Aircraft - Registration: [N390C](https://openairdocs.org/deregistered/N390C-2005-03-30), registration cancelled 2005-03-30, S/N 108-3390, built 1947 (OpenAirDocs) - Reported make and model: Stinson 108-2 - Registry model: [Stinson 108-2](https://openairdocs.org/model/stinson-108-2) (registry code 9230406) (OpenAirDocs) - Registry engine: [Franklin 6A4165 series](https://openairdocs.org/engine/franklin-6a4165-series) (registry code 27025, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 108-3390 - Airframe hours: 748 - Engines: Franklin 6A4-165 165 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Allan G.
