Location: Ponca City, OK
Accident Number: CEN17LA251
Date & Time: 07/02/2017, 1430 CDT
Registration: N2463H
Aircraft: CODY HAWKINS JA30 SUPERSTOL
Aircraft Damage: Substantial
Defining Event: Fuel contamination
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Personal
Analysis
The private pilot was conducting a local flight in an experimental airplane. During takeoff, the pilot thought that the airplane's performance was sluggish. The pilot indicated that the airplane started to lose lift, so he reduced the control stick input. He maneuvered the airplane around trees, but the airplane continued to descend, so the pilot decided to land. The airplane made a hard landing, causing the airplane's landing gear to collapse because it was sideloaded, and the airplane then skidded into a tree.
During a postaccident examination, a repair station noted contamination in one of the fuel jets and both carburetors. After replacing the fuel jet and cleaning the carburetors, the engine produced normal power. The cause of the contamination could not be determined.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be:
Contamination of the fuel system, resulting in a partial loss of engine power and subsequent off-airport landing.
Findings
Aircraft
Fuel - Fluid condition (Cause)
Fuel injector nozzle - Damaged/degraded (Cause)
Fuel control/carburetor - Damaged/degraded (Cause)

Factual Information
On July 2, 2017, about 1430 central daylight time, an Cody Hawkins JA30 SuperSTOL airplane, N2463H, collided with trees and terrain near Ponca City, OK. The private rated pilot and passenger were not injured, and the airplane sustained substantial damage. The airplane was registered to and operated by a private individual under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Visual meteorological conditions prevailed for the flight, which operated without a flight plan. The local flight was departing from a private field at the time of the accident.
According to information provided by the pilot, during the initial climb, the airplane's performance felt sluggish. The pilot added that the airplane started to lose lift, so the he reduced back stick pressure. The pilot maneuvered around trees and descended into terrain. The airplane's landing gear was side-loaded during the landing and collapsed. The airplane then slid to a stop. Substantial damage was sustained to the fuselage and wings.
The Rotax 914 UL2-01 engine was transported to a repair facility to be returned to service. The mechanic reported that when he functionally tested the engine, it run "rough." Further inspection of the engine found a fouled fuel jet and contaminants in the carburetors. The source of the contaminants could not be determined. After the cleaning the carburetors and replacing the idle jet, the engine produced normal power.
