# NTSB IAD97LA042: Cessna 310F, N1761G, Bridgeport, CT, January 17, 1997 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: January 16, 1997, 22:25 local (Jan 17, 1997, 03:25 UTC) - Place: Bridgeport, CT - Location: 41.1635° N, 73.1262° W: Placed by OpenAirDocs at BRIDGEPORT/SIKORSKY (BDR), within about a mile (OpenAirDocs) - Nearby events: https://openairdocs.org/map.md?lat=41.1635&lon=-73.1262&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report October 30, 1998 - Report: Approved by Office Director - NTSB case key (mKey): 28173 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=IAD97LA042 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/28173/pdf - Page: https://openairdocs.org/ntsb/IAD97LA042 ## Probable cause the pilot's inadequate compensation for wind conditions, and his failure to maintain directional control of the airplane during the landing roll. Related factors were: the pilot's misunderstanding of the wind conditions, and the resultant quartering tail wind. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - light condition - night - weather condition - crosswind (contributing factor) - weather condition - tailwind (contributing factor) - communications - not understood, pilot in command (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - directional control - not maintained, pilot in command (cause) - ground loop/swerve - On ground/water collision with object, landing - roll - object - vasi light/system ## Analysis On a night cross-country flight, the pilot accepted a visual approach to his destination. He requested information for the active runway, but was told the tower was closed. The controller stated that the last reported wind was, '0154 Zulu, two eight zero at one two gusts at one seven.' The pilot reported that he misunderstood the controller and thought the 'wind was 010 degrees at 29 knots.' The pilot landed on runway 6, and stated that 'shortly after touch down, a strong quarterly tailwind pushed the aircraft off (the right side) of the runway.' Before stopping, the airplane struck the VASI at the approach end of runway 24. The wind was recorded as 290 degrees at 21 knots with gusts to 28 knots. ## Factual narrative On January 16, 1997, at 2225 eastern standard time, a Cessna 310F, N1761G, was substantially damaged when it collided with the Visual Approach Slope Indicator System (VASI) on landing rollout at the Sikorsky Memorial Airport, Bridgeport, Connecticut. The commercial pilot and passenger were not injured. The airplane was registered to Duncan Air Service and operated by Flint Aviation Services, Inc., located at the Bishop International Airport, Flint, Michigan. Night visual meteorological conditions prevailed and a instrument flight rules flight plan was filed for the positioning flight conducted under 14 CFR Part 91. The pilot received a weather briefing from Lansing Flight Service Station and departed Bishop International Airport, about 2000. In the local Bridgeport area, the pilot accepted a visual approach and requested information for the active runway at Sikorsky Memorial Airport. The Air Traffic Controller responded, "they (tower) are closed, I don't know what the active is. The last reported wind at 0154 Zulu, two eight zero at one two gusts at one seven." The pilot acknowledged the controller and switched to the airport's unicom frequency. The pilot reported that he miss heard the controller and thought the "wind was 010 degrees at 29 knots." The pilot landed on runway 06 (4,677 feet long/150 feet wide) and stated, "shortly after touch down, a strong quarterly tailwind pushed the aircraft off (the right side) of the runway." Before stopping, the airplane struck the VASI at the approach end of runway 24. Afterwards, the pilot taxied the airplane to the tie down area. A review of the Sikorsky Memorial Airport Aviation Routine Weather Report indicated the wind was 290 degrees at 21 knots with gusts to 28 knots. ## Aircraft - Registration: N1761G (not matched to a registry record) - Reported make and model: Cessna 310F - Category: Airplane - Serial number: 310R1223 - Airframe hours: 5888 - Engines: Continental IO-520-M 285 horsepower reciprocating - Damage: Substantial damage - Flight: Positioning, Part 91 - Registered owner: Flint Aviation Inc. - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, December 16, 1996, 87 hours before - Departed: FNT, FLINT, MI - Destination: BDR - Flight plan: IFR - Airport: BDR, Bridgeport Sikorsky Mem, runway 6, 4,677 × 150 ft, asphalt ## Flight crew As NTSB recorded them.

Collided w ith VASI on landing rollout. Quartering tailwind pushed 310 off runway. Misunderstood wind direction. From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
