Location: Holland, MI
Accident Number: CEN16LA363
Date & Time: 09/03/2016, 1830 EDT
Registration: N4513S
Aircraft: CGS AVIATION HAWK AERO II
Aircraft Damage: Destroyed
Defining Event: Loss of control in flight
Injuries: 1 Serious
Flight Conducted Under: Part 91: General Aviation - Personal 

On September 3, 2016, at 1830 eastern daylight time, an experimental light sport CGS Aviation Hawk Aero II airplane, N4513S, collided with power line(s) and terrain during an en route climb following takeoff from Park Township Airport (HLM), Holland, Michigan. The airplane was destroyed. The pilot sustained serious injuries. The airplane was registered to and operated by the pilot under 14 Code of Federal Regulations Part 91 as a personal flight that was not operating on a flight plan. Day visual meteorological conditions prevailed at the time of the accident. The local flight was originating at the time of the accident.

A National Transportation Safety Board (NTSB) Pilot/Operator Accident/Incident Report (form 6120.1) was not received from the pilot.

The pilot, who was the airplane owner, stated in a telephone conversation with the NTSB Investigator-In-Charge, that the engine never stopped running and was not running at a high engine speed. During the climbout after takeoff, the engine started to sputter about 80-100 feet above ground level. The airplane "started stalling," so he pushed the nose down to increase airplane airspeed to recover from the aerodynamic stall. He said that if the airplane had not hit the power line(s), he would not have been involved in an accident.

Post-accident examination of the airplane and an engine run were performed at the pilot's hangar by a representative from the engine manufacturer and by the Federal Aviation Administration Coordinator for the accident. The engine was a Rotax 582 MOD 99, serial number 543 7309.

The examination revealed that all the spark plugs were NGK BR8ES that had removable resistor caps, which was not in accordance with the engine manufacturer's maintenance manual. The spark plug gaps were 0.29 - 0.30 inch (the engine maintenance manual specifies a gap size of 0.020 inch). All the spark plugs' electrodes exhibited a color consistent with a rich fuel mixture. The number 4-cylinder spark plug on the magneto side of the engine was loose and did not meet the torque specification in accordance with the engine manufacturer's maintenance manual.

The power takeoff and magneto sides of the engine had both carburetors equipped with larger main jets, which were 190 size jets instead of the engine manufacturer's original equipment, which were 165 size jets (higher jet numbers equate to a richer mixtures). Both carburetor chokes were blocked off and removed from service. Both jet needles clip positions were in the number 4 position and not in the number 3 position, as specified in the engine manufacturer's maintenance manual.

There were no fuel filters installed between the fuel pumps and carburetors as specified in the engine manufacturer's maintenance manual. The pneumatic fuel pump was found installed on the engine with the small drain hole near the impulse connection, positioned horizontally. The engine manufacturer's maintenance manual states that "The fuel pump should be installed in a cool place (not on the engine itself), with the small drain hole near the impulse connection towards the bottom. This hole drains oil condensate from the pump diaphragm chamber".

The gascolator was installed with industrial style (non-airplane) brass plumbing fittings and an industrial style (non-airplane) shut-off valve. Plumbers thread seal tape was present on the threads of the fuel line fittings. There was no fire sleeve on any of the fuel lines.

The fuel header tank was a white plastic container that was consistent with a water jug. The threaded cap of the header tank had a fuel system quick release type connector attached with a pick-up tube that extended to the bottom of the container. When the quick release type connector was tested, it leaked a substantial amount of air into the fuel system.

The engine manufacturer's maintenance manual stated: "Quick release type connectors can cause air leaks and produce fuel flow restrictions and possible blockage sites" "the tiniest flaw in any joint will cause air to be sucked into the fuel system, considerably reducing the capacity of the fuel pump. Air leaks are much more dangerous when the fuel tank is mounted below the fuel pump and carburetors"

The engine was run for several minutes with multiple throttle inputs during which no anomalies in engine power occurred.

Following the accident, the engine manufacturer issued a publication, "Two-Stroke Safety Issues", which in part discussed fuel system air leaks and the use of quick release connectors in the fuel system.

PARK TOWNSHIP, MI -- A 60-year-old Delton man was seriously injured when the engine on an ultralight aircraft quit, causing it to strike wires and overturn at the Ottawa County Fairgrounds.

Michael Kerr was taken to Holland Hospital with reported head and neck injuries following the 5:56 p.m. crash Saturday, Sept. 3.

Ottawa County sheriff's deputies said Kerr had taken off at the nearby Park Township Airport in a 2004 Gemini Twin ultralight aircraft when he began to experience engine trouble.

Kerr intended to fly to Wayland.

He turned the aircraft in hopes of landing in a grassy field at the fairgrounds at 1286 Ottawa Beach Road.

The engine then quit and he tried to glide the aircraft to the ground.

Ottawa County sheriff's investigators said the ultralight hit a light pole and wires surrounding the infield to the grandstand area. It then overturned and crashed.

The Federal Aviation Administration was called to investigate the crash.
