What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot was conducting a maintenance check flight in the experimental aircraft at cdn airport in SC. After approximately 45 minutes, the pilot observed oil streaming from the cowling and coating the windscreen. The pilot returned to the airport, and while attempting to land, failed to lower the landing gear resulting in minor damage to the airplane. While interviewing the pilot, the inspector learned that the gear in-transit light remained on during the entire flight. The gear in-transit light and oil coated windscreen most likely distracted the pilot and allowed him to land gear up
