On December 19, 2015, about 1120 Atlantic standard time, an experimental amateur-built Rans S-12XL, N124LP, was substantially damaged during a forced landing following a total loss of engine power near Guanica, Puerto Rico. The sport pilot was not injured. Visual meteorological conditions prevailed, and no flight plan was filed for the flight, which originated from Dr Hermenegildo Ortiz Quinones Airport (X63), Humacao, Puerto Rico, about 1015, and was destined for Eugenio Maria de Hostos Airport (TJMZ), Mayaguez, Puerto Rico. The personal flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91.
According to the pilot, he performed a preflight and engine run up with no anomalies noted. He flew the airplane for about an hour before the engine "sounded weird," then began to lose power, until the engine experienced a total loss of power. The pilot unsuccessfully attempted to restart the engine two times using the emergency checklist prior to preforming a forced landing to a field. During the landing, the airplane incurred substantial damage to the fuselage.
A postaccident examination of the engine revealed that there was fuel noted in the fuel tanks, fuel pump, fuel filter, and both carburetors. One spark plug was removed from each cylinder and thumb compression was obtained from all cylinders. However, when the propeller was rotated by hand, a metal scraping sound was heard in the vicinity of the gear box. The engine oil was drained and metal particles were noted in the oil.
The engine was retained for further examination.
