A contributing factor was the check pilot's failure to completely configure the airplane for a single engine go-around in a timely way. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power, go-around (vfr) - reason for occurrence undetermined (contributing factor) - 1 engine - In flight collision with terrain/water, go-around (vfr) - aircraft performance,engine out capability - deteriorated - remedial action - delayed, check pilot (contributing factor) - terrain condition - ground ## Analysis The airplane impacted terrain following a loss of engine power during a go-around on final approach. The check airman, who was giving a multiengine check ride to a private pilot, asked the pilot to conduct a short field landing. The check airman believed that they were too low while on final approach, with the landing gear and flaps extended. He asked the pilot if he thought everything was O.K. The pilot did not respond, so the check airman initiated a go-around by applying full power and retracting the landing gear. During the application of power for the go-around, the left engine failed to produce full power. The airplane veered to the left and its left wing impacted the ground. Pertinent sections of the pilot's operating handbook for the Beech B95 were reviewed. The recommended approach speed for a short field landing is 82 mph indicated airspeed, while best single engine rate of climb airspeed (Vyse) is 100 mph indicated. The procedure specified for a single engine go-around is as follows: 1) Apply full power to operating engine; 2) retract landing gear and close cowl flaps on dead engine; 3) retract flaps to half extension initially, then fully retract the flaps as soon as practical thereafter. The single engine rate of climb chart predicts a 160-foot-per-minute positive climb at the pressure altitude and temperature existing at the accident site; however, this performance is predicated on the airplane being in the following configuration: 1) at Vyse; 2) gear and flaps retracted; 3) inoperative engine's propeller feathered; 4) 5-degree bank into the operating engine. Any deviation from the listed single engine climb configuration would result in a degradation of the climb performance. Given that the airplane was likely in an energy deficient state some 15 to 18 mph below best single engine climb airspeed and not in the proper configuration for a single engine go-around when the loss of power in the left engine became apparent, a successful outcome for the maneuver was in doubt. The aircraft and left engine were examined by FAA inspectors with assistance by certificated mechanics; however, the reason for the left engine's failure to respond could not be determined. ## Factual narrative On November 29, 2001, at 0919 Pacific standard time, a Beech B95, N2012C, collided with terrain following a loss of engine power during a go-around at Henderson Executive Airport, Henderson, Nevada. Neither the check airman/examiner nor the pilot-rated student were injured; the airplane was substantially damaged. The flight was being operated by Sheble Aviation, Henderson, under the provisions of 14 CFR Part 91 as a multiengine check ride flight. Visual meteorological conditions prevailed, and a company flight plan had been filed. The flight originated at Henderson about 0745 as a local area check ride. According to the check airman, he was giving a multiengine check ride to the pilot and asked him to conduct a short field landing. The check airman believed that the pilot was too low on the approach with full flaps extended. He asked the pilot if he thought everything was O.K. He did not receive a response, so he "intervened" and told the control tower that they were executing a go-around. The check pilot applied full power and retracted the landing gear, but delayed flap retraction until they had a climb established. Upon application of the power, the left engine "failed to produce full power" and they were unable to reach the runway or conduct the go-around. The airplane's left wing impacted the ground and the airplane spun around. The airplane came to rest upright facing the northeast approximately 100 yards to the left of the runway threshold. Pertinent sections of the pilot's operating handbook for the Beech B95 were reviewed. The recommended approach speed for a short field landing is 82 mph indicated airspeed, while best single engine rate of climb airspeed (Vyse) is 100 mph indicated. The procedure specified for a single engine go-around is as follows: 1) Apply full power to operating engine; 2) retract landing gear and close cowl flaps on dead engine; 3) retract flaps to half extension initially, then fully retract the flaps as soon as practical thereafter. The single engine rate of climb chart predicts a 160-foot-per-minute positive climb at the pressure altitude and temperature existing at the accident site; however, this performance is predicated on the airplane being in the following configuration: 1) at Vyse; 2) gear and flaps retracted; 3) inoperative engine's propeller feathered; 4) 5-degree bank into the operating engine. Any deviation from the listed single engine climb configuration would result in a degradation of the climb performance. The Federal Aviation Administration (FAA) inspectors (airworthiness and operations) who responded to the accident site reported finding the engine controls (mixtures, propellers, and throttles) in the full forward position. The magneto switches were found in the OFF position, but the pilots reported turning them off prior to exiting the airplane. The landing gear handle was in the retracted position and the landing gear appeared to be retracted. The flap handle was in the retracted position and the flaps appeared to be retracted. Both fuel selector valves were selected to the main fuel tanks and both tanks contained a large quantity of fuel. The FAA airworthiness inspector reviewed the airplane's maintenance records. The left engine had the left magneto replaced the day before the accident. The airworthiness inspector asked a mechanic to check the left engine's magneto-to-engine timing, which revealed no anomalies. ## Aircraft - Registration: [N2012C](https://openairdocs.org/deregistered/N2012C-2003-02-19), registration cancelled 2003-02-19, S/N TD-430, built 1960 (OpenAirDocs) - Reported make and model: Beech B95 - Registry model: [Beech B95](https://openairdocs.org/model/beech-b95) (registry code 1153404) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: TD-430 - Airframe hours: 9429.9 - Engines: Lycoming O-320-A1A 180 horsepower reciprocating; Lycoming O-360-A1A 180 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Sheble Aviation - Registered owner: Wolfe Leasing Company, Inc. - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, August 28, 2001 - Departed: HND, Henderson, NV - Flight plan: Company VFR - Airport: HND, Henderson Executive, runway 17L, 5,000 × 75 ft, asphalt ## Flight crew As NTSB recorded them.
