Narrative:
The Cessna 208B aircraft took off from runway 27 at Clonbullogue Airfield (EICL), Ireland, at approximately 14:13 hours local time. At departure, the occupants on board were the pilot, who was seated in the left-hand cockpit seat, a passenger (a young child), who was seated in the right-hand cockpit seat, and 16 parachutists, who occupied two bench seats in the main cabin. The aircraft was operating the fifth parachuting flight that day and had been operating each weekend at the airfield since 21 April 2018. The aircraft climbed to FL130 and permission for the drop was received from Dublin ATC. The pilot reported to ATC at 14:34 hrs advising that the drop was complete and the aircraft was in the descent. The pilot made contact with the Clonbullogue Airfield to advise that the aircraft was on left base. No further transmissions were received from the aircraft, and when it did not arrive as expected, the airfield personnel attempted to establish radio contact, but were unsuccessful.
The aircraft had impacted nose-down in boggy ground located in a forested area, approximately 2.5 NM to the north-west of the departure airfield. The impact site was compact, with minimal damage to the surrounding trees. The impact was such that the front section of the aircraft, forward of the main wheels, was buried in bog.

Probable Cause:
Impact with terrain following a loss of control in a steeply banked left-hand turn.
Contributory Cause(s):
1. The steeply banked nature of the turn being performed.
2. Propeller torque reaction following a rapid and large increase in engine torque.
3. The aircrafts speed while manoeuvring during the steeply banked turn.
4. Insufficient height above ground to effect a successful recovery.
