Incident Overview
The aircraft departed Kisumu International Airport at 1958LT on an Instrument Flight Rules (IFR) commercial scheduled passenger flight to Wilson Airport (HKNW) in Nairobi County. The Pilot-In-Command (PIC) was the pilot flying, and the First Officer (FO) was the pilot monitoring. Prior to takeoff, the flight crew conducted a ground briefing for the approach to Runway 06 at Jomo Kenyatta International Airport (HKJK), with the plan to maintain the Instrument Landing System (ILS) for HKJK RWY 06. It was discussed that if the flight crew became visual with HKNW RWY 32, they would break off the ILS approach and position for a right base to HKNW RWY 32. According to the flight plan, the alternate aerodromes were HKJK or Kilimanjaro International Airport (HTKJ).
Approach and Hard Landing
After becoming visual with HKNW RWY 32, the flight crew discontinued the ILS and initiated a visual approach for landing. The flight noticed the aircraft was too high when it crossed the threshold of RWY 32. The flight crew increased the descent rate to 700 feet per minute. An Enhanced Ground Proximity Warning System (EGPWS) "sink rate" warning sounded in the cockpit, immediately followed by a hard landing.
Runway Excursion and Damage
The hard landing caused the aircraft to lose control. It veered off to the right of the runway into the grass area and stopped approximately 30 metres from the runway edge. The nose landing gear collapsed, the left main landing gear detached, and the right main landing gear sustained damage. All 37 occupants evacuated safely.
Occupant Status
No injuries were reported among the 37 occupants, all of whom evacuated without incident.
