Probable cause
It is the opinion of the members of the Investigating Board that the pilot sighted Otoque Island and mistook it for Taboga and that he was in the vicinity of Otoque Island when he gave his estimated position of 15 miles southeast of the field. It is furtherbelieved that when the pilot called the tower and gave his estimated position as 5 miles south of field and at 1,000 feet on instruments that he thought he was past Taboga Island, approaching Albrook Field, and that by dropping down a little he would be contact again. Actually the estimated distance of 10 miles traveled would place him over Taboga from Otoque. The pilot, Captain Lawrence W. Parks, filed an instrument flight plan from Morrison Field, West Palm Beach, to Albrook Field, without holding a currently effective Instrument Pilot Certificate. AAF Form 8 (white) or AAF Form 8A (green) in violation of AAF Regulation 60-16A.
