Analysis

While in level flight the pilot reported both engines failed and all attempts to restart them were unsuccessful. The pilot then ditched the airplane in the Ocean, and it sank and was not recovered. The pilot and three passengers were rescued 2 days later. According to fuel consumption estimates there should have been adequate fuel for the entire flight and a reserve.
