# NTSB CHI06CA228: Piper PA-18, N2396J, Waukesha, WI, August 7, 2006 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: August 7, 2006, 13:00 local (18:00 UTC) - Place: Waukesha, WI - Coordinates: 43.047222, -88.236114 - Nearby events: https://openairdocs.org/map.md?lat=43.0472&lon=-88.2361&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 31, 2006 - Report: Approved by Office Director - NTSB case key (mKey): 64340 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI06CA228 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/64340/pdf - Page: https://openairdocs.org/ntsb/CHI06CA228 ## Probable cause The pilot's inadequate compensation for the crosswind and failure to maintain directional control which resulted in a groundloop. Factors included the closed runway and the crosswind condition. ## 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) - compensation for wind conditions - inadequate, pilot in command (cause) - ground loop/swerve - encountered, pilot in command - airport facilities,runway/landing area condition - closed (contributing factor) - weather condition - crosswind (contributing factor) ## Analysis The tailwheel equipped airplane ground looped during the landing rollout. The pilot reported that he had performed two stop and go landings at another airport before landing at the accident airport. He reported that runway 18/36 was closed and runway 28 was the active runway. He reported that he noticed that the windsock was "straight out" indicating that the winds were from the south creating a left crosswind landing. He reported that during the landing rollout "the aircraft ground looped to the right hitting the left wing on the runway." About 15 minutes prior to the accident, the reported winds were 340 degrees at 5 knots. ## Factual narrative The tailwheel equipped airplane ground looped during landing rollout.
