The CVR did not reveal approach briefing and any checklist reading. On final approach of runway 28 passing 800 feet approach light insight and landing clearance was received. Prior to touchdown, control of the aircraft was transferred from co-pilot to PIC. The CVR recorded that the Ground Proximity Warning Systems (GPWS) warned “Sink Rate” and “Pull Up”. The right wheel track was found out of the runway for about 4 meter away and return to the runway. The aircraft stopped for about 100 meters from taxiway N3.

Flight attendants evacuated the passengers via all exits available and door slides were inflated. The two passengers were minor injured, and the aircraft suffered severe damage.
