This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
On March 11, 2014, about 0910 Hawaiian standard time, a special light sport Revo Evolution Trikes weight-shift control aircraft, N98EV, impacted terrain and was consumed by fire in Kekaha, Hawaii. Birds in Paradise, LLC., owned by the accident pilot, was operating the trike under the provisions of 14 Code of Federal Regulations (CFR) Part 91. The certified light sport instructor and student pilot sustained fatal injuries; the trike was destroyed. Visual meteorological conditions prevailed and no flight plan was filed for the instructional flight. The trike departed Port Allen Airport, Hanapepe, Hawaii about 0850 and the introductory flight was intended to take 60 minutes before returning to the airport.
A second Birds in Paradise certificated flight instructor (CFI) was giving instruction in another trike while flying in close proximity with the accident trike. He stated that about 0615 that morning he met up with the accident pilot at the company's facilities. They began to take their respective trikes out of the hangar and he noticed the accident pilot was on a ladder routing compressed air into the accident trike's fuel vent. The second pilot commented to the accident pilot that the fuel cap was still affixed on the tank and removed it for him, which produced a "pop" sound from the compressed air escaping the system. They wheeled the trikes over to the staging area and greeted their student pilots shortly thereafter. After fitting the students with flight suits and helmets, the pilots gave them a briefing and departed around 0850.
After departure, the accident pilot told the second pilot that he was going "on company," meaning that they would communicate to one another on the company frequency 123.450; this was the last transmission the CFI heard from the accident pilot.
Approaching the Barking Sands class D airspace, the second pilot transmitted over the company frequency that he was switching to the Barking Sands frequency to receive a clearance from the control tower, to transition through their airspace as a flight of two.
As the CFI's trike was approaching the northwest side of Polihale Beach , he descended to about 600 feet above ground level (agl) and observed the accident trike about 1,000 feet agl and 75 feet away horizontally at his 1-o'clock position; that was the last time he saw the accident trike flying. The CFI and his student performed two near-360 degree turns over the ocean and attempted to contact the accident pilot over the radio. They noticed smoke on the base of the ridgeline and maneuvered over to the area.
The trike came to rest at the base of a ridgeline about one nautical mile east of Polihale State Park. The main wreckage was consumed by fire but all major structural components were located within the wreckage debris area. The accident pilot had recently had problems with the fuel system suctioning the fuel supply out of the main vent line (located in the belly of the aircraft). In an effort to rectify the problem, he routed the vent line up the mast and through the keel pocket toward the trailing edge.
The wreckage and a camera were recovered for further examination.

A first training flight ... in formation and/or close proximity to another aircraft.
Really? I don't think that there is any sane CRI or jury that would consider this a real training flight.

We pilots hope the FAA fixes this by enforcing the current regulations instead of prohibiting flight training in S-LSA aircraft!

According to information from the FAA, commercial operators of these aircraft may use them for flight instruction but not for sightseeing purposes, and in 2011 operators on the island — including Charlebois — were given a warning after it was found some operators were “trying to get around the air tour prohibition by offering scenic flights under the guise of ‘introductory flight instruction’.”
The FAA warning came in the wake of several fatalities during the previous few years.
Another FAA safety meeting was held with Charlebois and the other operators in 2013.
It would be a HUGE stretch to call this a training flight :ignore:
