# NTSB DEN04LA128: Beech 95-B55, N120F, Roosevelt, UT, August 20, 2004 - Type: NTSB accident investigation - Classification: Accident · Minor injuries · Limited investigation · Final report - Date: August 20, 2004, 06:30 local (12:30 UTC) - Place: Roosevelt, UT - Coordinates: 40.279907, -109.999298 (estimated) - Nearby events: https://openairdocs.org/map.md?lat=40.2799&lon=-109.9993&mi=10 - Phase of flight: [Enroute](https://openairdocs.org/ntsb-phases/400) (OpenAirDocs' grouping) - Highest injury: Minor injuries - Injuries: 1 minor - Status: Completed, report March 30, 2005 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 59960 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DEN04LA128 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/59960/pdf - Page: https://openairdocs.org/ntsb/DEN04LA128 ## Probable cause the loss of engine power for undetermined reasons. A contributing factor was the lack of suitable terrain for a forced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - nonmechanical, climb - reason for occurrence undetermined (cause) - Forced landing, emergency descent/landing - In flight collision with object, emergency landing - object - tree(s) - In flight collision with terrain/water, descent - uncontrolled - terrain condition - none suitable (contributing factor) - terrain condition - ground ## Analysis According to the pilot, the left engine began to run rough shortly after departing runway 07. He noticed a loss in indicated fuel pressure and within a few moments, the left engine lost power and then quit. The pilot made several unsuccessful attempts to restart the engine. The pilot attempted an immediate left turn to return to the airport. The 270-degree left turn resulted in a loss of altitude and improper line-up with runway 25. The pilot completed a 90-degree right turn as the airplane crossed the airport's access road. The airplane continued to descend as it struck several trees and impacted terrain southwest of the airport. The impact separated both engines and the nose and main landing gear assemblies from the fuselage. Approximately 3 feet of the outboard section of each wing was crushed upwards and aft. According to an FAA inspector, the mixture was in the full rich position and the fuel boost pumps were off. Although the airplane's right wing was compromised, there was visible fuel in the left wing. ## Factual narrative On August 20, 2004, at approximately 0630 mountain daylight time, a Beech 95-B55, N120F, piloted by a private pilot, was substantially damaged during a forced landing after takeoff from Roosevelt Municipal Airport (74V), Roosevelt, Utah. The pilot, the sole occupant on board, received minor injuries. Visual meteorological conditions prevailed at the time of the accident. The personal cross-country flight was being conducted under the provisions of Title 14 CFR Part 91 without a flight plan. The flight was originating at the time of the accident. According to the pilot, the left engine began to run rough shortly after departing runway 07. He noticed a loss in indicated fuel pressure and within a few moments, the left engine lost power and then quit. The pilot said that he adjusted the mixture and made several unsuccessful attempts to restart the engine. The pilot attempted to return to the airport, but he was unable to maintain altitude, and was forced to land in a field southwest of the airport. According to an FAA inspector, the pilot attempted an immediate left turn to return to the airport. The 270-degree left turn resulted in a loss of altitude and improper line-up with runway 25. The pilot completed a 90-degree right turn as the airplane crossed the airport's access road. The airplane continued to descend as it struck several trees and impacted terrain southwest of the airport. The impact separated the nose and main landing gear assemblies from the fuselage. Approximately 3 feet of the outboard section of each wing was crushed upwards and aft. Both engines were separated from the airplane. According to the inspector, the pilot stated that he visually checked both tanks for fuel before takeoff. During the initial climb, the pilot kept the mixture in the full rich position and did not turn the fuel boost pumps on after the left engine began to run rough. Although the airplane's right wing was compromised, there was visible fuel in the left wing. The airplane's last annual inspection was performed on March 3, 2004, at a tachometer reading of 416.8 hours. The tachometer reading at the time of the accident was 417.3 hours. According to the inspector, the pilot's logbook showed approximately 1,268 hours of flight time, of which 326 hours were in a Beech 95-B55, including 7.2 hours since March 18, 2004, that was logged in N120F. On November 17, 2004, an examination of the left engine revealed that the engine's oil pan and exhaust manifold were crushed upward, the intake manifold was crushed aft and the left magneto was separated from the engine. Due to impact damage, a test-run of the engine could not be accomplished. The propeller spinner was crushed aft and twisted in a counter-clockwise direction. Both propeller blades showed torsional bending and chordwise scratches. Engine continuity was confirmed. The pilot did not provide a Pilot Operator Aircraft Accident Report (NTSB form 6120.1/2) for this accident. ## Aircraft - Registration: [N120F](https://openairdocs.org/deregistered/N120F-2013-08-05), registration cancelled 2013-08-05, S/N TC-684, built 1964 (OpenAirDocs) - Reported make and model: Beech 95-B55 - Registry model: [Beech 95-B55 (T42A)](https://openairdocs.org/model/beech-95-b55-t42a) (registry code 1152706) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: TC-684 - Airframe hours: 4491 - Engines: Continental IO-470 reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Leon Ross Drilling and Construction Inc. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 3, 2004, 0.5 hours before - Departed: 74V, Roosevelt, UT - Destination: GJT, Roosevelt, UT - Airport: 74V, Roosevelt Municipal ## 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.
