Probable cause

Fuel starvation induced power loss, a compromised fuel vent system, and improper installation of the plumbing in the fuel vent system.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Loss of engine power(partial) - nonmechanicalTakeoff - initial climb
Loss of engine power(total) - nonmechanicalManeuvering - turn to landing area (emergency)
Fluid,fuel - starvationCause
Fuel system,line fitting - separationCause
Maintenance,installation - improperCompany/operator managementCause
Forced landingDescent - emergency
On ground/water encounter with terrain/waterLanding - roll
Terrain condition - ditch

Analysis

After takeoff and at an altitude of approximately 200 feet AGL, the engine began to lose power. Power continued to decay and the pilot initiated a left turn to return for landing on runway 35. As power continued to decrease the pilot realized that he would not be able to continue his turn sufficiently to align with the runway. A forced landing was made and the airplane collided with a depression between the runway and taxiway. According to the pilot, a fuel line separated from a 't' fitting in the fuel vent system, causing the power loss.
