Investigation Docket - National Transportation Safety Board:

Location: Loveland, Colorado
Accident Number: CEN19FA143
Date & Time: May 15, 2019, 12:48 Local
Registration: N60RK
Aircraft: Beech 60 
Aircraft Damage: Destroyed
Defining Event: Loss of engine power (total)
Injuries: 1 Fatal
Flight Conducted Under: Part 91: General aviation - Ferry


The commercial pilot was relocating the multiengine airplane following the completion of an extensive avionics upgrade, which also included the installation of new fuel flow transducers. As the pilot neared the destination airport, he reported over the common traffic advisory frequency that he had "an engine out [and] smoke in the cockpit." Witnesses observed and airport surveillance video showed fire emanating from the airplane's right wing. As the airplane turned towards the runway, it entered a rightrolling descent and impacted the ground near the airport's perimeter fence.

The right propeller was found feathered. Examination of the right engine revealed evidence of a fire aft of the engine-driven fuel pump. The fuel pump was discolored by the fire. The fire sleeves on both the fuel pump inlet and outlet hoses were burned away. The fuel outlet hose from the fuel pump to the flow transducer was found loose. The reason the hose was loose was not determined. It is likely that pressurized fuel sprayed from the fuel pump outlet hose and was ignited by the hot turbocharger, which resulted in the inflight fire.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
A loss of control due to an inflight right engine fire due to the loose fuel hose between the engine-driven fuel pump and the flow transducer.

On May 15, 2019, at 1248 mountain daylight time, a Beech 60, N60RK, was destroyed when it collided with terrain during an emergency landing at Northern Colorado Regional Airport (FNL), Loveland, Colorado. The pilot was fatally injured. The airplane was registered to Majeste Air LLC, and was being operated as a Title 14 Code of Federal Regulations (CFR) Part 91 personal flight. Visual meteorological conditions existed at the accident site at the time of the accident, and no flight plan was filed for the flight which originated from Rocky Mountain Metropolitan Airport (BJC), Broomfield, Colorado, about 1230, was destined for FNL.

The airplane had been at BJC since July 2017 for the installation of new avionics which included a primary flight display (PFD); multi-function display (MFD); a backup to the electronic flight instrument system (EFIS); two navigation, communication, and GPS units, a transponder, audio panel, and associated wiring.

According to individuals who performed work on the airplane, a Hobbs meter oil hose was installed, as well as a longer fuel line in order to use the same mounting locations for the fuel flow transducers. This was only required on the right engine because of the location of air conditioning compressor.

Three engine runs were conducted after the work was completed. The first test run revealed an oil leak in the left engine oil pressure transducer. The line was retorqued and the two subsequent engine runs revealed no anomalies. In a telephone conversation about 2 weeks before the accident, the pilot stated that he was applying for a Federal Aviation Administration (FAA) ferry permit because the airplane's annual inspection had expired. The pilot arrived at the airport about 1130. He did not have a ferry permit and no ferry permit inspection was conducted.

At 1217, the pilot contacted BJC ground control and requested a "high-speed taxi" before takeoff. The request was granted, and the pilot made the high-speed taxi on runway 12L. He was subsequently cleared for takeoff at 1226.

At 1247, the pilot reported on the FNL common traffic advisory frequency that he was on the left downwind leg for runway 15 and that he had "an engine out [and] smoke in the cockpit." The pilot of another airplane advised that he could see the fire and that the runway was clear. The accident pilot replied, "I've got a fire. I'm gonna land it pretty darn quick. Please have the trucks come on out." There were several ground witnesses, one of which said that the airplane's right wing was on fire before the accident.

A video taken by an airport security camera showed the airplane on a base leg for runway 15. Fire could be seen on the right side of the airplane. The airplane completed two full rolls as it descended before impacting a dry retention pond about ¼-mile from the approach end of the runway.

The airplane came to rest upright on a magnetic heading of 072° at an elevation of 4,869 ft mean sea level (msl).

The right engine was located about 40 ft northeast of the main wreckage. The right wing was separated just outboard of the right nacelle and came to rest on a heading of 192°. Fire had consumed the inboard right wing, which was oriented on a heading of 020°. The left wing was also destroyed by fire; it was oriented on a magnetic heading of 204°.

The rudder and right elevator were destroyed by fire, but the left elevator was intact and oriented on a magnetic heading of 090°. The fuselage and instrument panel were destroyed by fire. Control cable continuity was established to all flight controls from their attach points through tensile overload failures. The flap actuators were consumed by fire. The left main landing gear was found in the retracted position. The nose landing gear and right main landing gear were separated during the impact sequence. The actuating arm indicated that the landing gear was extended.

Continuity and compression were established on the right engine except for cylinder Nos. 1, 3 and 5 due to impact damage, A significant area of thermal damage was observed in the vicinity of the engine-driven fuel pump. The fuel line from the pump to the fuel flow transducer was loose and could be moved by hand. The fuel strainer screens clean, but each bowl contained burnt material. Both fuel selector valves were positioned on the main tanks. Continuity and compression were established on the left engine. The magnetos were thermally damaged and did not spark.

The right propeller remained attached to the engine and was in the feathered position. Two blades were straight and unremarkable; the third blade exhibited S-bending. The left propeller remained attached to the left engine. One blade remained attached to the hub and was bent slightly forward at midspan. The other two blades separated from the hub; one blade was straight, the other was fractured at midspan.

The left side of the right engine sustained heavy impact damage. The turbocharger pipes were displaced to the right, and the flange bolts were sheared off to the right. The air conditioning hoses were completely consumed by fire. There was evidence of fire aft of the engine-driven fuel pump. The fuel pump was discolored by fire. The fire sleeves on both the fuel pump inlet and outlet hoses were burned away. The fuel outlet hose to the flow transducer was loose. 

Medical And Pathological Information

An autopsy was performed on the pilot by the Larimer County Chief Medical Examiner in Loveland, Colorado. The cause of death was attributed to blunt force and thermal injuries.

Toxicological screening performed by FAA's Forensic Sciences laboratory found no evidence of carboxyhemoglobin or ethanol in blood, or drugs in urine. A cyanide test was not performed.


  1. The engines on the Duke are 380 up each

    1. Not this one chief. Please take note that the engines were not the original Lycoming TIO-541-B4 380hp but instead the reduced 310hp Lycoming TIO-541-E1C4 engines. Why the current or previous owner(s) chose to lose 140hp of power available on a notorious handful of an aircraft in engine out ops is anyone's guess. Cost maybe. But I sure wouldn't have done that in this beast.

    2. More time between overhaul. And less cost.

    3. Well I figured it had to be cost related, but if you find TBO costs to be a little high for the aircraft/powerplant the originals were, then you are buying more aircraft that you can afford for your MRO budget. Never mind the impact on performance loss (specifically in single engine ops at the worst time).
