# NTSB DEN00LA105: Froelich Lancair IV, N493K, Bountiful, UT, June 8, 2000 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: June 8, 2000, 08:45 local (14:45 UTC) - Place: Bountiful, UT - Coordinates: 40.890617, -111.929786 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=40.8906&lon=-111.9298&mi=10 - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report January 18, 2001 - Report: Approved by Office Director - NTSB case key (mKey): 49382 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DEN00LA105 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/49382/pdf - Page: https://openairdocs.org/ntsb/DEN00LA105 ## Probable cause The loss of power for undetermined reasons and the pilot's unsuccessful remedial action (dive to avoid the power line). Contributing factors were the power line, the tires and the fence. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - nonmechanical, descent - fluid,fuel - excessive flow/output (contributing factor) - Forced landing, emergency descent/landing - In flight collision with object, landing - roll - object - wire,transmission (contributing factor) - terrain condition - none suitable (cause) ## Analysis The pilot descended from 10,500 feet msl (above mean sea level) to 6,500 feet msl in preparation for landing, using 15 inches of manifold pressure. When he advanced the throttle, there was no response from the engine, and the tachometer indicated 1,660 rpm. The destination airport was 7 miles away and the airplane was at 1,300 feet agl, so he decided to make a forced landing in an open field. Unable to glide over power lines ahead, he dove under and clipped one of the lines with the vertical stabilizer. The airplane then struck a pile of tractor tires, went through a fence, and spun around. Postaccident inspection by an FAA inspector revealed fuel in the line leading to the spider. The pilot said he suspected he lost power due to a flooded engine. ## Factual narrative On June 8, 2000, approximately 0845 mountain daylight time, a Froelich Lancair IV, N493K, registered to and operated by the pilot, was substantially damaged when it collided with terrain during a forced landing in Bountiful, Utah. The commercial pilot, the sole occupant aboard, received a minor injury. Visual meteorological conditions prevailed, and no flight plan had been filed for the personal flight being conducted under Title 14 CFR Part 91. The flight originated at Tooele, Utah, approximately 0820. According to the pilot's accident report, he descended from 10,500 feet msl (above mean sea level) to 6,500 feet msl in preparation for landing, using 15 inches of manifold pressure. When he turned south and advanced the throttle, there was no response from the engine, and the tachometer indicated 1,660 rpm (revolutions per minute). Skypark Airport was 7 miles to the south and the airplane was at an altitude of 1,300 feet agl (above ground level). He decided to make a forced landing in an open field. Unable to glide over power lines ahead, the pilot dove the airplane under and clipped one of the power lines, tearing off the top portion of the rudder. The airplane then stuck a pile of tractor tires, went through a fence, and spun around. Postaccident inspection by an FAA inspector revealed fuel in the line leading to the spider. The pilot said he suspected he lost power due to a flooded engine. ## Aircraft - Registration: [N493K](https://openairdocs.org/deregistered/N493K-2003-04-22), registration cancelled 2003-04-22, S/N LIV065, built 1995 (OpenAirDocs) - Reported make and model: FROELICH LANCAIR IV - Registry model: [Froelich Robert E LANCAIR IV](https://openairdocs.org/model/froelich-robert-e-lancair-iv) (registry code 05601FK) (OpenAirDocs) - Registry engine: [Amateur-built UNKNOWN ENG](https://openairdocs.org/engine/amateur-built-unknown-eng) (registry code 99999) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: LIV065 - Airframe hours: 305 - Engines: Continental TSIO-550-B1B 350 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Robert E.

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.
