# NTSB CHI07CA103: Cessna 172S, N967SP, Naples, FL, April 14, 2007 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: April 14, 2007, 10:43 local (14:43 UTC) - Place: Naples, FL - Coordinates: 26.151388, -81.771942 - Nearby events: https://openairdocs.org/map.md?lat=26.1514&lon=-81.7719&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report August 30, 2007 - Report: Approved by Office Director - Parties: Federal Aviation Administration, Miami FSDO - NTSB case key (mKey): 65665 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI07CA103 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/65665/pdf - Page: https://openairdocs.org/ntsb/CHI07CA103 ## Probable cause The pilot's failure to maintain directional control of the airplane during landing. A contributing factor to the accident was the runway marker 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 - directional control - not maintained, pilot in command (cause) - On ground/water collision with object, landing - object - airport sign/marker (contributing factor) ## Analysis The airplane veered off the left side of the runway during landing and hit a runway marker sign. The pilot reported that the airplane touched down on runway 14 (5,000 feet by 100 feet, asphalt) with "left aileron in" and "slight" right rudder because winds were from approximately 110 degrees magnetic. After touchdown, she applied full engine power and additional right rudder because the airplane was not established on the runway centerline. The airplane veered to the left and the pilot "reduced power to idle and braked." The right main landing gear collided with a runway marker sign which caused the gear assembly to separate from the airplane. The left brake, nose wheel steering and rudder operation were tested and found to operate as designed. ## Factual narrative The airplane veered off the left side of the runway during landing and hit a runway marker sign.
