Détails:
A Shorts 360-200 cargo plane crashed into the water off Sint Maarten-Juliana Airport (SXM), shortly after takeoff from runway 27. Both pilots were killed.
The accident flight 7101 operated as a scheduled cargo flight returning from Sint Maarten-Juliana Airport to San Juan International Airport, Puerto Rico.
The flight was approved for engine start by the Juliana Tower at 18:17 local time. The flight commenced taxi to runway 28 at 18:28. The flight was cleared for take-off at 18:38 and instructed to maintain heading 230 until passing 4,000 feet.
At 18:39 the flight was given their departure time and instructed to maintain heading 230 until passing 3000 feet. The crew read back the clearance. At 18:40 Tower personnel observed a normal take-off and initial climb.
The aircraft passed the departure runway threshold on take-off and attained a maximum GPS altitude of 433 feet at 119 knots groundspeed at 18:39:30. It then entered a left hand descending turn at an increasing airspeed until it struck the water.

Probable Cause:

Causes/contributing factors:
The investigation believes the PF experienced a loss of control while initiating a turn to the required departure heading after take-off. Flap retraction and its associated acceleration combined to set in motion a somatogravic illusion for the PF. The PF's reaction to pitch down while initiating a turn led to an extreme unusual attitude and the subsequent crash. PM awareness to the imminent loss of control and any attempt to intervene could not be determined. Crew resource management (CRM) performance was insufficient to avoid the crash.
Contributing factors to the loss of control were environmental conditions including departure from an unfamiliar runway with loss of visual references (black hole), night and rain with gusting winds.
