A factor was a partial loss of power in the left engine due to a loose oil line. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(partial) - mech failure/malf, climb - to cruise - engine shutdown - performed, pilot in command - 1 engine - failure,partial - lubricating system,oil line - loose (cause) - Loss of engine power(total) - nonmechanical, descent - emergency - reason for occurrence undetermined (cause) - 1 engine - failure,total - Forced landing, descent - emergency - In flight collision with terrain/water, emergency landing - terrain condition - grass ## Analysis The pilot completely fueled the airplane prior to departure. After takeoff, while climbing through 16,000 feet msl, to reach a cruising altitude of 23,000 feet, the left manifold pressure gauge began to fluctuate. The pilot then noticed oil streaking from the left engine cowling, and shut down the left engine. The pilot notified ATC and began to fly back toward the departure airport; however, about 1 minute 40 seconds after securing the left engine, the right engine experienced a total loss of engine power. The pilot stated that he had not touched the right fuel selector prior to the loss of power in the right engine. The pilot attempted to restart the right engine using a checklist and cross-feeding the right engine to the left main fuel tank, but the right engine did not restart. With no success to restart the right engine, the pilot attempted to restart the left engine, but was unable to do so. During the restart attempts, the airplane's engine driven vacuum instruments failed, which included the attitude indicator. The ATC controller was providing the pilot vectors toward an ILS approach to a suitable alternate airport. Due to instrument meteorological conditions between 1,200 feet and 14,500 feet, the controller had to provide no-gyro turns to the pilot in an attempt to maintain a safe attitude. The pilot was unable to glide to the runway, and performed a forced landing to a field about 3 miles south of the alternate airport. Examination of the left engine revealed that the oil line was found separated from the number two cylinder, but the threads remained intact. The number six cylinder exhibited damage consistent with oil starvation. However, no discrepancies were noted with the right engine. ## Factual narrative On July 9, 2003, at 1313 eastern daylight time, a Beech BE-56TC, N156DK, was substantially damaged when it impacted a field during a forced landing, following a loss of engine power while climbing near Bethany, West Virginia. The certificated private pilot was seriously injured. Visual meteorological conditions prevailed for the flight that departed Wood County Airport (PKB), Parkersburg, West Virginia, at 1238. An instrument flight rules flight plan was filed for the planned flight to Watertown International Airport, Watertown, New York. The personal flight was conducted under 14 CFR Part 91. The pilot stated that he "topped off" the fuel tanks prior to departure. While climbing through 16,000 feet msl, to reach a cruising altitude of 23,000 feet, the left manifold pressure gauge began to fluctuate. He then noticed oil streaking from the left engine cowling. The pilot shut down and secured the left engine, and advised Air Traffic Control (ATC) that he wanted to return to PKB. About "a minute or so" after the pilot had secured the left engine, the right engine lost all power. The pilot added that he had not touched the right fuel selector after takeoff. Review of recorded communications between the pilot and ATC revealed that he reported a total loss of power in the right engine approximately 1 minute and 40 seconds after reporting a loss of power in the left engine. The pilot verified that the right throttle lever, right mixture lever, and right propeller lever were properly set, and then moved the right mixture lever full forward as a precaution. He verified the magnetos and fuel boost pump were "ON," and that the right fuel selector was "ON" for the right main fuel tank. However, the right engine did not restart. The pilot then attempted to start the right engine as if he were on the ground, utilizing the start checklist. He also attempted to cross-feed the right engine to the left main fuel tank. With no success to restart the right engine, the pilot attempted to restart the left engine, but was unable to do so. During the restart attempts, the airplane's engine driven vacuum instruments failed, which included the attitude indicator. The ATC controller provided the pilot vectors toward the ILS Runway 03 approach to Wheeling Ohio County Airport (HLG), Wheeling, West Virginia. However, due to instrument meteorological conditions between 1,200 feet and 14,500 feet, the controller had to provide "no-gyro" turns to the pilot in an attempt to maintain a safe attitude. The pilot was unable to glide to the runway, and performed a forced landing to a field about 3 miles south of HLG. During the landing, the right main landing gear collapsed, and the wings, fuselage, and empennage sustained substantial damage. A Federal Aviation Administration inspector examine the airplane with a representative from the engine manufacturer. On the left engine, an oil line was found separated from the number two cylinder, but the threads remained intact. The number six cylinder exhibited a lack of continuity and damage to the piston and connecting rod, consistent with oil starvation. Examination of the right engine did not reveal any pre-impact mechanical malfunctions. Thumb compression was obtained on all cylinders, and engine continuity was confirmed. Adequate oil remained in the right engine, and the right engine driven fuel pump contained residual fuel. Continuity was confirmed for the right engine driven fuel pump, and the fuel nozzles appeared absent of debris. The fuel screen was removed from the fuel injection servo. The screen was absent of residual fuel and debris. When the right engine magnetos were tested, they produced spark at all leads. Examination of the spark plugs did not reveal any anomalies. ## Aircraft - Registration: [N156DK](https://openairdocs.org/deregistered/N156DK-2005-07-18), registration cancelled 2005-07-18, S/N TG21, built 1967 (OpenAirDocs) - Reported make and model: Beech BE-56TC - Registry model: [Beech 56TC](https://openairdocs.org/model/beech-56tc) (registry code 1152736) (OpenAirDocs) - Registry engine: [Lycoming TI0-541 series](https://openairdocs.org/engine/lycoming-ti0-541-series) (registry code 41536, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: TG21 - Airframe hours: 2189 - Engines: Lycoming TIO-541 380 horsepower reciprocating; Lycoming TIO-540 SER 380 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Mark A.

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.
