Narrative:
A Cessna 208B Grand Caravan EX, PK-SNW, overran the runway on landing in rainy conditions at Sinak Airport (NKD/WABS), Puncak Regency, Papua, Indonesia.
On the seventh flight of the day, the aircraft departed from Timika at 12:20 LT to Sinak carrying four people on board. The aircraft also carried 1,048 kg of cargo. The captain acted as Pilot Flying (PF) and the copilot acted as Pilot Monitoring (PM).
The aircraft cruised at an altitude of 13,500 feet and the flight was uneventful. During cruising, the captain was informed by another aircraft pilot that the weather at Sinak was rain and suitable for visual flight. The captain acknowledged and was aware about the weather condition and decided to continue the flight.
About 7 nm from Sinak, when the aircraft altitude was about 2000 feet Above Ground Level (AGL), the captain disengaged the autopilot and switched to manual flying. The copilot performed the lading checklist.
About 1000 feet AGL, the Enhanced Ground Proximity Warning System (EGPWS) aural warning "sinkrate" active twice. The copilot noticed that the aircraft speed was higher than normal and called out "speed" then the captain responded by a call "correcting".
At 13:07 LT, during landing the aircraft floated before touchdown, then pilot retracted the flap position to TO/APP. After touchdown, the captain applied the brake. He noticed that the aircraft speed was high and the aircraft would overrun the runway. The captain decided to bring the aircraft to the left side of the end of the runway which considered as the safest and suitable area.
After the aircraft stopped, the pilots and the passengers safely evacuated from the aircraft by themselves. The captain had a minor face injury and receiving medical attention. The aircraft was substantially damaged.
