# NTSB CHI95LA099: Cessna 152, N4598B, Waukesha, WI, March 9, 1995 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: March 9, 1995, 17:52 local (23:52 UTC) - Place: Waukesha, WI - Coordinates: 43.020969, -88.290313 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=43.0210&lon=-88.2903&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report November 25, 1996 - Report: Approved by Office Director - NTSB case key (mKey): 9848 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI95LA099 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/9848/pdf - Page: https://openairdocs.org/ntsb/CHI95LA099 ## Probable cause the student pilot's failure to maintain directional control during an aborted takeoff. A factor was the snow covered ground which contributed to the airplane nosing over as it departed the runway. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - aborted - directional control - not maintained, pilot in command (cause) - ground loop/swerve - inadvertent, pilot in command - On ground/water encounter with terrain/water, takeoff - aborted - terrain condition - snow covered (contributing factor) - Nose over, takeoff - aborted ## Analysis THE SOLO STUDENT PILOT WAS PERFORMING TOUCH-AND-GO LANDINGS, LANDED LONG AND ABORTED THE TAKEOFF PORTION. WINDS WERE FROM 50 DEGREES LEFT OF THE NOSE AT 5 KNOTS, AND THE RUNWAY WAS DRY. DIRECTIONAL CONTROL WAS NOT MAINTAINED, THE AIRPLANE DEPARTED THE RIGHT EDGE OF THE RUNWAY, AND FLIPPED OVER WHEN THE WHEELS DUG INTO SNOW. ## Factual narrative On March 9, 1995, at 1752 central standard time (CST), a Cessna 152, N4598B, operated as a rental aircraft by Waukesha Flying Service, Inc., of Waukesha, Wisconsin, departed the right side of runway 18 at Waukesha County Airport (UES) and was substantially damaged. Visual meteorological conditions existed at the time of the accident, and winds were from 130 degrees at 5 knots. No flight plan was filed, and the student solo instructional training flight was conducted under 14 CFR Part 91. The tower controller stated that the flight originated from UES and entered the closed traffic pattern at 1715 CST. During the accident landing, the airplane landed approximately 1,500 feet down the 3,599 foot long by 75 foot wide runway. The controller stated that it appeared the pilot attempted to abort his takeoff and veered off the runway near the departure end of runway 18. The student pilot stated that he was performing practice touch and go landings and attempted to abort a takeoff. He reported that as the airplane departed the runway edge, the wheels entered deep snow, the airplane became partially airborne, yawed approximately 100 degrees left, and came to rest upright. The pilot was uninjured, the propeller was bent, and the left wingtip was deformed. The pilot did not describe, nor were any mechanical anomalies found with the airplane. ## Aircraft - Registration: [N4598B](https://openairdocs.org/deregistered/N4598B-2019-09-06), registration cancelled 2019-09-06, S/N 15283548, built 1979 (OpenAirDocs) - Reported make and model: Cessna 152 - Registry model: [Cessna 152](https://openairdocs.org/model/cessna-152) (registry code 2071835) (OpenAirDocs) - Registry engine: [Lycoming 0-235 series](https://openairdocs.org/engine/lycoming-0-235-series) (registry code 41505, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 15283548 - Airframe hours: 5477 - Engines: Lycoming O-235-L2C 110 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Waukesha Flying Service, Inc - Airworthiness certificate: Standard, Utility - Last inspection: Annual, February 14, 1995, 27 hours before - Airport: UES, Waukesha County, runway 18, 3,599 × 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.
