# NTSB CHI97TA198: Cessna 182R, N661SP, Peoria, IL, July 6, 1997 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Final report - Date: July 6, 1997, 08:45 local (13:45 UTC) - Place: Peoria, IL - Location: 40.6936° N, 89.5890° W: Placed by OpenAirDocs: center of Peoria, IL, within about 6 miles (OpenAirDocs) - Nearby events: https://openairdocs.org/map.md?lat=40.6936&lon=-89.5890&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report February 2, 1998 - Report: Approved by Office Director - NTSB case key (mKey): 10717 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI97TA198 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/10717/pdf - Page: https://openairdocs.org/ntsb/CHI97TA198 ## Probable cause the pilot's improper use of carburetor heat and the carburetor icing conditions which existed at the time of the accident. Factors were the ditch and poles which the airplane contacted. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(partial) - nonmechanical, approach - vfr pattern - final approach - weather condition - carburetor icing conditions (cause) - carburetor heat - improper use of, pilot in command (cause) - Forced landing, emergency descent/landing - On ground/water collision with object, landing - roll - terrain condition - ditch (contributing factor) - landing gear,nose gear - overload - object - pole (contributing factor) ## Analysis While on final approach the pilot advanced the throttle; however, the engine power did not increase. A forced landing was made in a soybean field. The airplane contacted a ditch at which time the nose gear collapsed. The airplane then continued across a road where it contacted two sign posts. Post accident inspection failed to reveal any failure/malfunction which would have prevented normal operation of the engine. It was noted, however, that the spark plugs were sooted. The engine functioned normally during a test run. The temperature/dew point (68 and 56 degrees F respectively) is conductive to moderate icing at cruise power or serious icing at glide power. ## Factual narrative On July 6, 1997, at 0845 central daylight time, a Cessna 182R, N661SP, operated by the Illinois State Police, collided with the terrain and a sign post during a forced landing following a loss of engine power. The airplane was on final approach to runway 31 at the Greater Peoria Regional Airport, Peoria, Illinois, when the loss of power occurred. The commercial pilot reported minor injuries. Visual meteorological conditions prevailed. The airplane was substantially damaged. The public use flight originated from Springfield, Illinois, at 0815 cdt. The pilot stated that he had the power reduced during his approach to land. When he advanced the throttle to add power, the engine power did not change. There was not increase or decrease in power. Due to obstacles between his position and the runway he elected to make a forced landing in a soybean field just north of the approach path for runway 31. He reported he touched down in the field but it was too short. The airplane contacted a ditch at which time the nose gear collapsed. The airplane continued across a road and came to rest after contacted two sign posts. Post accident inspection of the engine by a Federal Aviation Administration Inspector failed to reveal any malfunction/failure which would have prevented normal operation of the engine although it was noted that the spark plugs were sooted. The engine was later test run by the Illinois State Police who reported that it started and ran without interruption. According to a carburetor icing probability chart, the temperature and dew point, 68 degree F. and 56 degrees F. respectively, present at the time of the accident were conducive to moderate icing at cruise power or serious icing at glide power. ## Aircraft - Registration: N661SP (not matched to a registry record) - Reported make and model: Cessna 182R - Category: Airplane - Serial number: 18268564 - Airframe hours: 6655 - Engines: Continental O-470-U reciprocating - Damage: Substantial damage - Flight: Business, Part 91 - Registered owner: Illinois State Police - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, June 19, 1997, 31 hours before - Departed: SPI, SPRINGFIELD, IL - Destination: PIA ## 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.
