# NTSB SEA06CA190: Coltrin RV-6, N566JH, Burley, ID, September 27, 2006 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: September 27, 2006, 13:00 local (19:00 UTC) - Place: Burley, ID - Coordinates: 42.542221, -113.764167 - Nearby events: https://openairdocs.org/map.md?lat=42.5422&lon=-113.7642&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 1 uninjured - Status: Completed, report February 26, 2007 - Report: Approved by Office Director - Parties: FAA FSDO - NTSB case key (mKey): 64864 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=SEA06CA190 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/64864/pdf - Page: https://openairdocs.org/ntsb/SEA06CA190 ## Probable cause A loss of engine power due to the malfunctioning of the carburetor. A factor was the airplane nosing over due to the rough/uneven terrain. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - mech failure/malf, approach - vfr pattern - base turn - fuel system,carburetor - failure (cause) - Forced landing, emergency descent/landing - Nose over, landing - roll - terrain condition - rough/uneven (contributing factor) ## Analysis The pilot said he had entered downwind for landing and had pulled the throttle back to idle prior to turning base. While on base, he pushed the throttle forward to clear the engine; the engine did not respond. The pilot changed fuel tanks, checked boost pump, and manipulated the throttle with no engine response. He performed a forced landing to a potato field and the aircraft flipped inverted immediately after touchdown. The left horizontal stabilizer and the vertical stabilizer were bent and wrinkled. The pilot said that the engine's carburetor had been worked on within the year and he believes the power loss was due to the malfunctioning of the carburetor. ## Factual narrative On September 27, 2006, at approximately 1300 mountain daylight time, a Coltrin RV-6 experimental homebuilt airplane, N566JH, was substantially damaged when it flipped inverted following a forced landing attempt near the Burley Municipal Airport, Burley, Idaho. The commercial pilot, the sole occupant on board, was not injured. The pilot/owner was operating the airplane under Title 14 CFR Part 91. Visual meteorological conditions prevailed for the personal local flight which had originated approximately 50 minutes before the accident. The pilot had not filed a flight plan.

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.
