Factors were, the pilot/owners failure to obtain an annual condition inspection, and the corn crop. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Airframe/component/system failure/malfunction, cruise - maintenance,annual inspection - not obtained, pilot in command (contributing factor) - lubricating system,oil tubing - failure (cause) - Loss of control - in flight, landing - flare/touchdown - stall - intentional, pilot in command - In flight collision with terrain/water, emergency descent/landing - precautionary landing - performed, pilot in command - unsuitable terrain or takeoff/landing/taxi area - encountered, pilot in command (contributing factor) - terrain condition - crop (contributing factor) ## Analysis The airplane was damaged during a precautionary landing after an oil line failure during flight. The pilot said that the plastic oil line from the engine to the oil pressure gauge failed. He said that thick smoke and oil were present and he elected to land the airplane before a fire could start. He said that there were only corn fields and he stalled the airplane about 10 feet above the ground during the precautionary landing. He stated that the airplane hit the ground and the shoulder harness attachment broke loose. The pilot/owner reported that the most recent annual condition inspection was performed on July 5, 1998. ## Factual narrative On September 16, 2002, at 1810 central daylight time, an amateur-built Bailey DSA-1, N304MB, owned and piloted by a private pilot, was substantially damaged during a precautionary landing after an oil line failure during flight.
