# NTSB CHI06CA166: Piper PA-28-140, N1910T, Walworth, WI, June 25, 2006 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: June 25, 2006, 12:00 local (17:00 UTC) - Place: Walworth, WI - Coordinates: 42.531387, -88.654998 - Nearby events: https://openairdocs.org/map.md?lat=42.5314&lon=-88.6550&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report October 3, 2006 - Report: Approved by Office Director - Parties: FAA-Milwaukee FSDO - NTSB case key (mKey): 64102 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI06CA166 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/64102/pdf - Page: https://openairdocs.org/ntsb/CHI06CA166 ## Probable cause The pilot's delay in initiating a go-around and the resulting failure to maintain clearance to the vehicle on the adjacent roadway. The short length of the runway selected by the pilot and the vehicle were contributing factors. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight collision with object, go-around (vfr) - go-around - delayed, pilot in command (cause) - clearance - not maintained, pilot in command (cause) - terrain condition - short runway/landing area (contributing factor) - object - vehicle (contributing factor) - In flight collision with terrain/water, go-around (vfr) - terrain condition - ground ## Analysis The airplane was substantially damaged when the right wing struck a vehicle on a roadway adjacent to the runway during a go-around attempt. The pilot and passenger reported no injuries. The pilot stated that he entered a left downwind for runway 36 (2,108 feet by 100 feet, turf). He noted that the downwind, base and final traffic pattern legs were "normal." He reported that the final approach flown would have allowed the airplane to touchdown within the initial one-third of the runway length. He stated, "Close to touchdown I experienced a float and what I believe was a strong wind shear." He reported that he applied full engine power and initiated a go-around, however, the right wing tip subsequently struck a minivan on an adjacent roadway. The airplane continued approximately 600 feet and came to rest in a cornfield. The pilot reported no malfunctions or failures with the airplane prior to the accident. He noted that the accident might have been avoided by initiating a go-around "at the first sign of any trouble especially on a runway that is only 2100 [feet] long." ## Factual narrative The airplane was substantially damaged when the right wing struck a vehicle on a roadway adjacent to the runway during a go-around attempt. The pilot and passenger reported no injuries. The pilot stated that he entered a left downwind for runway 36 (2,108 feet by 100 feet, turf) at Big Foot Airfield (7V3), Walworth, Wisconsin. He noted that the downwind, base and final traffic pattern legs were "normal." He reported that the final approach flown would have allowed the airplane to touch down within the initial one-third of the runway length. He stated, "Close to touch down I experienced a float and what I believe was a strong wind shear." He reported that he applied full engine power and initiated a go-around, however, the right wing tip subsequently struck a minivan on an adjacent roadway. The airplane continued approximately 600 feet and came to rest in a cornfield. The pilot reported no malfunctions or failures with the airplane prior to the accident. He noted that the accident might have been avoided by initiating a go-around "at the first sign of any trouble especially on a runway that is only 2100 [feet] long." ## Aircraft - Registration: [N1910T](https://openairdocs.org/aircraft/N1910T), registered now, S/N 28-7125464, built 1971 (OpenAirDocs) - Reported make and model: Piper PA-28-140 - Registry model: [Piper PA-28-140](https://openairdocs.org/model/piper-pa-28-140) (registry code 7102802) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 28-7125464 - Airframe hours: 4899 - Engines: Lycoming O-320-E2A 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Utility; Standard, Normal - Last inspection: Annual, December 1, 2005 - Departed: UES, Waukesha, WI - Destination: 7V3, Walworth, WI - Airport: 7V3, Big Foot Airfield, runway 36, 2,108 × 100 ft, grass/turf ## Flight crew As NTSB recorded them.

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.
