The left fuel vent check valve was installed correctly, and the line was free of obstructions from the inlet into the tank.
Examination of the right fuel supply revealed the fuel tank outlet screen was clean.
The fuel vent interconnect was separated, but the line was free of obstructions from the left to right side.
Examination of the airframe fuel supply revealed the fuel strainer did not contain any fuel; the screen was clean but the bowl contained brown colored dust.

Examination of the empennage revealed it was displaced to the right with the leading edge of the horizontal stabilizer contacting the right side of the empennage.
The vertical stabilizer with attached rudder and right horizontal stabilizer remained attached, while the left horizontal stabilizer and elevator were separated but found in close proximity to the main wreckage.
Examination of the left horizontal stabilizer revealed a semi-circular dent on the leading edge near the root; the left elevator was pulled from the torque tube.
The elevator trim tab actuator was extended 1-11/16 inches as measured from the housing to the center of the rod end attach bolt, which equated to tab trailing edge 4 degrees up.
Examination of the engine revealed all cylinders and the oil sump remained attached, although the oil sump was breached and crushed.
The carburetor and attached airbox were impact separated but remained attached by the control cables.
The throttle was partially open and the mixture control was near the full rich position.
An impact mark on the mixture stop boss adjacent to the "R" position was noted; the mixture control cable broke during removal.
The inlet fitting of the carburetor was broken off and the carburetor bowl did not contain any fuel.
Further inspection of the carburetor revealed a gap was noted between the throttle body and bowl near the accelerator pump.
The carburetor was retained for further examination.
Crankshaft, camshaft, and valve train continuity, and thumb suction and compression were confirmed to cylinder Nos.
1, 2, and 4.
Continuity was also observed to the rear of the engine.
The No.
3 cylinder intake pushrod was dented aft, which precluded movement of the intake valve.

Slight chordwise scratches were noted on the cambered side of the blade, and nicks were noted on the leading edge.
Fuel Information The airplane was last fueled on September 19, 2015.
According to fueler, both fuel tanks were filled with 100 low lead fuel to the top of each filler neck opening.
The airplane had not been operated between the fueling and the departure of the accident flight.
Immediately after the accident, fuel operations at VGC were suspended.
Subsequent checks of airport fuel samples for specific gravity and contaminates did not reveal any anomalies.
Further, there were no reports of fuel related issues from other airplanes that were fueled from the same source as the accident airplane.
Weight and Balance Information The latest weight and balance dated May 28, 2015, indicated that the airplane's empty weight was 1,086.29 pounds.
Estimated weight calculations that were performed based on a full fuel load at takeoff, and the weights of the pilot and passenger (140 pounds each) reported during autopsy, revealed that the airplane was operating within its weight limitations at takeoff.
An external examination of the pilot, and an autopsy of the passenger were performed by Onondaga County Medical Examiner, Syracuse, New York.
