# NTSB CHI98LA226: Cessna 150H, N50433, Osceola, WI, June 28, 1998 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: June 28, 1998, 15:45 local (20:45 UTC) - Place: Osceola, WI - Coordinates: 45.310321, -92.689117 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=45.3103&lon=-92.6891&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 2 minor - Status: Completed, report February 15, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 10940 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI98LA226 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/10940/pdf - Page: https://openairdocs.org/ntsb/CHI98LA226 ## Probable cause the student pilot's incomplete preflight, and the instructor pilot's inadequate supervision of the student's preflight. Factors were the fuel contaminated with water, and the roadway encountered during the forced landing rollout. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - nonmechanical, takeoff - initial climb - fuel system - contamination,water (contributing factor) - aircraft preflight - improper, dual student (cause) - supervision - inadequate, pilot in command(cfi) (cause) - Forced landing, emergency descent/landing - On ground/water encounter with terrain/water, landing - roll - terrain condition - roadway/highway (contributing factor) - Nose over, landing - roll ## Analysis In the written statement the instructor said that during the preflight the student found water in the fuel. He indicated that there was additional fuel drawn in an attempt to remove the water. He said he was confident that no water was left in the system. After conducting some touch and go landings, and during initial climb, the engine suffered a total loss of power. A forced landing was conducted in an area where the airplane impacted a roadway and nosed over. A subsequent examination of the gascolator found about 80% water contained in the sample drawn from that location. ## Factual narrative On June 28, 1998, at 1545 central daylight time, a Cessna 150H, N50433, experienced a loss of engine power during an initial climb during takeoff from the Osceola Airport, Osceola, Wisconsin. The flight instructor pilot and commercial pilot (student) received minor injuries. The airplane sustained substantial damage. The aircraft was being operated as an instructional flight under 14 CFR Part 91 and had been performing touch & go landings. Visual meteorological conditions prevailed and no flight plan was filed. The flight was departing with the intended destination of Blaine, Minnesota, when the accident occurred.. According to a written statement by the pilot, water was found while draining fuel during the pre-flight check. Several sumps were performed to remove water and contaminants from the fuel. The pilot stated they were very confident no water could be left in the system. After performing a touch and go landing at Osceola, Wisconsin, at 200 feet the engine sputtered and quit. The instructor took over the controls and conducted a forced landing. On rollout, the airplane impacted a road and nosed over. During a subsequent post accident investigation, a fuel sample taken from the gascolator revealed approximately 80% water in the sample. The inspector's report is attached as an addendum to this report. ## Aircraft - Registration: [N50433](https://openairdocs.org/deregistered/N50433-1998-09-21), registration cancelled 1998-09-21, S/N 15069300 (OpenAirDocs) - Reported make and model: Cessna 150H - Registry model: [Cessna 150H](https://openairdocs.org/model/cessna-150h) (registry code 2071818) (OpenAirDocs) - Category: Airplane - Serial number: 15069300 - Airframe hours: 4025 - Engines: Continental O-200-A 100 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Gail Erickson - Airworthiness certificate: Standard, Normal; Standard, Utility - Last inspection: Annual, February 27, 1998, 37 hours before - Departed: OEO, OSCEOLA, WI - Destination: ANE, BLANE, MN ## Flight crew As NTSB recorded them.
