Captain / Total hours on type:
500
Circumstances:
The pilot reported that the #2 engine began to lose power as he was flying under a low overcast and about 500 feet above the Yukon River. Subsequently, the airplane descended and the fuselage and left propeller contacted the water. With these problems and decreasing visibility ahead, the pilot elected to make a 180° turn. He said that about midway through the turn, the #2 engine lost all power. The airplane then crashed into trees and was destroyed by a post-impact fire. No reason was found for either engine to lose power before water or tree contact.
Probable cause:
Failure of the pilot to maintain adequate altitude after becoming distracted with an engine problem. Factors related to the accident were: loss of power in the #2 engine for an unknown reason and the low overcast condition.
