He estimated that the swells were 5 to 10 ft high with crests 20 feet apart.

The crew performed the procedures for a restart with EPECS FAIL light and multiple other starts that were unsuccessful.Ībout 8,000 ft mean sea level, the crew committed to ditching in the ocean.Ībout 1600, after preparing the survival gear, donning life vests, and making mayday calls on VHF 121.5, the PIC performed a full flaps gear up landing at an angle to the sea swells and into The engine did not restart and grinding sounds and a loud bang were heard. The propeller never unfeathered and multiple CAS warning lights illuminated, including the EPECS FAIL light ( Engine and Propeller Electronic Control System). The crew secured the engine and attempted another air start. The propeller unfeathered and the engine started however, it did not reach flight idle and movement of the power control lever did not affect the engine. The CP went back to her crew seat and they commenced the pilot operating handbook’s emergency checklist procedures for emergency descent and then loss of engine power in flight. The PIC immediately placed the fuel boost pumps from AUTO to ON. The PIC stated that the crew alerting system (CAS) fuel low pressure light illuminated about 5 to 15 seconds after the transfer pumps were turned off, and then the engine lost power and the propeller auto feathered. When she determined that all of the usable fuel was transferred, and fuel still remained in the pressurized fuel line, she turned the transfer pumps to off and before she could access the transfer and tank valves, the engine surged and flamed out.
The crew was concerned about introducing air into the engine as they emptied the rear ferry tank, so the PIC placed the ignition switch to ON.Īccording to the copilot (CP), she went to the cabin to monitor the transparent fuel line from the transfer pumps to ensure positive fuel flow while she transferred the last of the available rear tank fuel to the main fuel line. At that time, the rear ferry fuel tank was almost empty, and the forward tank was about 1/2 full. The pilots each stated that the ferry fuel system worked as designed during the flight and they utilized the operating procedures that were supplied by the installer.Ībout 5 hours after takeoff, approaching ETNIC intersection, the PIC climbed the airplane to flight level 280. The aircraft departed Santa Maria about 1000. The ferry fuel supply line was connected to the factory installed ferry fuel line fitting at the left wing bulkhead, which then fed directly to the main fuel line through a check valve and directly to the turbine engine. The installed system was ground and flight checked before the trip. The final system consisted of 2 aluminum tanks, 2 transfer pumps, transfer and tank valves, and associated fuel lines and fittings. The system was modified with the addition of two 30 psi fuel transfer pumps that could overcome the ferry system check valve.

About 1 month before the trip, the pilot hired a ferry company to install an internal temporary ferry fuel system… The crew attempted the first transoceanic flight on November 2, but the ferry fuel system did not transfer properly, so the crew diverted to Merced Airport ( KMCE), California. The manufacturer had an auxiliary ferry fuel line and check valve installed in the left wing before delivery. Leg was planned for 10 hours from Santa Maria Airport ( KSMX), California to Hilo Airport ( PHTO), Hawaii. …the pilot-in-command (PIC), who was also the ferry company owner….and another pilot were ferrying a new airplane from California to Australia.
