Détails:
Castle Aviation flight CSJ921, a Swearingen SA-226AT Merlin IV, N54GP, was destroyed when it crashed into the bank of the Merimack River, about 600 m short of the threshold of runway 6 at Manchester-Boston Regional Airport, NH (MHT), New Hampshire, USA. The sole pilot onboard was fatally injured.
The airplane was on the ILS approach to runway 6 at Manchester Boston Regional Airport in darkness. During the approach, the pilot reported an engine failure at 23:30:42 but did not specify which engine. The aircraft crashed nine seconds later.
Examination of the propellers showed that the propeller blades from the no.1 (left) engine did not exhibit rotational damage. The right propeller blades appeared to be at or near the feathered position.
This might indicate that both engines had failed, or that the wrong prop was being feathered.
