# NTSB CHI07CA175: Luscombe 8A, N45468, London, OH, June 20, 2007 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Data collection · Final report - Date: June 20, 2007, 09:30 local (13:30 UTC) - Place: London, OH - Coordinates: 39.932777, -83.461944 - Nearby events: https://openairdocs.org/map.md?lat=39.9328&lon=-83.4619&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report July 25, 2007 - Report: Approved by Office Director - NTSB case key (mKey): 66156 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI07CA175 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/66156/pdf - Page: https://openairdocs.org/ntsb/CHI07CA175 ## Probable cause The pilot's failure to maintain directional control of the airplane and the pilot's inadequate compensation for the crosswind which resulted in a ground loop and subsequent collision with a taxiway sign. Factors contributing to the accident include the crosswind and the taxiway sign. ## 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 - directional control - not maintained, pilot in command (cause) - ground loop/swerve - encountered, pilot in command - terrain condition - runway - weather condition - crosswind (contributing factor) - compensation for wind conditions - inadequate, pilot in command (cause) - On ground/water collision with object, landing - roll - object - airport sign/marker (contributing factor) - landing gear,main gear - overload ## Analysis The pilot was landing the tailwheel aircraft on runway 27 (4,001 feet by 75 feet, asphalt) with a right-hand crosswind. The pilot stated that upon touchdown "contact came before alignment was complete" and the airplane turned to the right. The pilot reported that he "overcompensated and got into an oscillation" and the airplane ground looped. The airplane departed the right side of the runway and struck a taxiway sign. The pilot stated in his accident report that the accident could have been prevented by performing a go around. Wind conditions reported at an airport, located 15 nautical miles east of the accident site, were: 350 degrees at 8 knots. ## Factual narrative The airplane was substantially damaged when it ground looped and impacted a taxiway sign following a landing on runway 27 (4,001 feet by 75 feet, asphalt). The pilot reported that as he was on final he was crabbing into the wind to maintain the runway centerline. When he approached the runway, he applied aileron into the wind and left rudder "to align with the centerline and cancel drift." The pilot reported that he contacted the runway before the alignment was complete and the airplane turned to the right. The pilot reported that he "over-compensated and got into an oscillation" and the airplane ground looped. The airplane subsequently departed the right side of the runway and struck a taxiway sign. The pilot stated in his accident report that the accident could have been prevented by performing a go around. Wind conditions reported at Bolton Field Airport, 15 nautical miles east of the accident site, near the time of the accident were: Wind 350 degrees at 8 knots. ## Aircraft - Registration: [N45468](https://openairdocs.org/aircraft/N45468), registered now, S/N 1995, built 1946 (OpenAirDocs) - Reported make and model: Luscombe 8A - Registry model: [Luscombe 8A](https://openairdocs.org/model/luscombe-8a) (registry code 8190104) (OpenAirDocs) - Registry engine: [Continental A&C75 series](https://openairdocs.org/engine/continental-a-c75-series) (registry code 17005, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 1995 - Airframe hours: 2578.1 - Engines: Continental A75-8 75 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, October 1, 2006 - Departed: 04I, Columbus, OH - Destination: London, OH - Airport: UYF, Madison County, runway 27, 4,001 × 75 ft, asphalt ## 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.
