What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On April 15, 2004, experimental aircraft N82LS departed on runway 21 in Borger, Texas, (bgd) at approximately 16:15 hours, CDT. After reaching pattern altitude the engine experienced high oil temperature indications along with diminished RPM. The pilot initiated a left crosswind, then initiated a downwind leg in the pattern but the engine was not producing sufficient RPM to maintain altitude. The pilot turned base leg and then short final to runway 21. The aircraft hit the sloping terrain approximately 100 feet from the threshold of the runway. The aircraft nosed over, slid for approximately 100 feet, and came to rest inverted at the threshold of runway 21. There was no injury to the single occupant; however, the aircraft sustained damage to the right wing, vertical stabilizer, rudder, fuselage, propeller, and canopy.
