# NTSB CHI96LA016: Cessna 170B, N4555C, Oconomowoc, WI, October 25, 1995 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: October 25, 1995, 09:00 local (14:00 UTC) - Place: Oconomowoc, WI - Coordinates: 43.100223, -88.490447 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=43.1002&lon=-88.4904&mi=10 - Phase of flight: [Initial climb](https://openairdocs.org/ntsb-phases/350) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report April 18, 1996 - Report: Approved by Office Director - NTSB case key (mKey): 10139 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI96LA016 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/10139/pdf - Page: https://openairdocs.org/ntsb/CHI96LA016 ## Probable cause a loss of engine power for undetermined reasons. A factor associated with the accident was the unsuitable terrain on which to make the forced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(partial) - nonmechanical, takeoff - initial climb - reason for occurrence undetermined (cause) - Forced landing, emergency descent/landing - In flight collision with terrain/water, landing - flare/touchdown - terrain condition - none suitable (cause) - Nose over, landing - flare/touchdown ## Analysis The pilot stated he added power to initiate the climb portion of his second touch and go landing when the engine did not seem to produce adequate power (1,000 rpm). He stated he then performed a 'straight ahead engine out type emergency landing.' The airplane nosed over upon contacting a corn crop during the landing. Post accident inspection and runup of the engine failed to reveal any anomalies which would have resulted in a loss of engine power. ## Factual narrative On October 25, 1995, at 0900 central daylight time, a Cessna 170B, N4555C, flown by a private pilot nosed over in a corn field during a forced landing on takeoff from a grass strip in Oconomowoc, Wisconsin. The 14 CFR Part 91 personal flight was operating in visual meteorological conditions without a flight plan. The pilot received minor injuries. The airplane was substantially damaged. This was a local flight which originated approximately one hour prior to the acicdent. The pilot stated that after a local flight, he returned to the Oconomowoc Airstrip where he performed a touch and go on runway 09 (1,000 long, sod). He stated that after the second landing, he applied power and initiated a takeoff climb. He stated that the engine "did not seem to develope adequate power (tach aprx 1000 rpm)... ." He stated he performed a straight ahead emergency landing into a corn crop. The airplane nosed over during the landing. The airplane was inspected by a Federal Aviation Airworthiness Inspector who was able to start the engine and run it up to 1,950 to 2,000 rpm. ## Aircraft - Registration: [N4555C](https://openairdocs.org/aircraft/N4555C), registered now, S/N 25499, built 1953 (OpenAirDocs) - Reported make and model: CESSNA 170B - Registry model: [Cessna 170B](https://openairdocs.org/model/cessna-170b) (registry code 2072306) (OpenAirDocs) - Registry engine: [Continental C145 series](https://openairdocs.org/engine/continental-c145-series) (registry code 17012, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 25499 - Airframe hours: 2863 - Engines: CONTINENTAL O-300-A 145 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Kurt S.

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.
