Summary
On 22 June 2026, an Airbus Helicopters EC135 P3H, registered PK-WSI, sustained a hard landing. During a recurrent flight training exercise at Weda Bay Airport involving simulated One Engine Inoperative (OEI) procedures, the helicopter experienced a loss of main rotor speed (NR) during a Vertical Take-Off and Landing (VTOL) approach.
