# NTSB CHI99LA067: Baker Fisher Horizon, N793DB, Bolivar, MO, January 16, 1999 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: January 16, 1999, 10:50 local (15:50 UTC) - Place: Bolivar, MO - Coordinates: 37.60046, -93.410499 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=37.6005&lon=-93.4105&mi=10 - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report September 7, 2000 - Report: Approved by Office Director - NTSB case key (mKey): 45615 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=CHI99LA067 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/45615/pdf - Page: https://openairdocs.org/ntsb/CHI99LA067 ## Probable cause The pilot's improper use of carburetor heat which resulted in carburetor icing and subsequent loss of engine power. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, cruise - weather condition - carburetor icing conditions (contributing factor) - fuel system,carburetor - ice (cause) - carburetor heat - improper use of, pilot in command (cause) - Forced landing, emergency descent/landing - On ground/water collision with object, landing - roll - object - fence (contributing factor) - terrain condition - none suitable (contributing factor) ## Analysis The pilot reported that after about 20 to 30 minutes of flying the engine began to lose power. He checked the magnetos, added carburetor heat, and changed throttle settings, but it did not restore engine power. The pilot said that he executed a forced landing into a field but it was too short and the airplane struck a fence. The pilot reported that he thought the 'engine problem was caused by carburetor ice. Flying at 1,000 feet there was not enough time for the carburetor heat to clear the ice.' The temperature was 44 degrees Fahrenheit and the dew point was 34 degrees Fahrenheit. According to a carburetor icing probability chart, the conditions were conducive for carburetor icing. ## Factual narrative On January 16, 1999, at 1050 central daylight time, an experimental Baker Fisher Horizon One, N793DB, sustained substantial damage during a forced landing when it hit a fence during landing roll. The pilot reported a loss of engine power. The private pilot received minor injuries. The 14 CFR Part 91 flight departed Bolivar Airport, Bolivar, Missouri, on a local flight. Visual meteorological conditions prevailed and no flight plan was filed. The pilot reported that after about 20 to 30 minutes of flying the engine began to lose power.

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.
