• Engines: 2x CFM56-7B
Sequence of Events
1. Approach and Landing:
• The aircraft conducted an approach to runway 25 at Molde Airport amidst challenging weather conditions, including strong winds and a slippery runway surface.
• Upon touchdown, the aircraft reportedly landed beyond the optimal touchdown zone.
2. Runway Overrun:
• Despite the crew’s efforts to slow the aircraft, it skidded on the wet and slippery runway surface and overran the runway by 150 meters.
• The aircraft stopped short of the sea by approximately 15 meters.
3. Evacuation:
• The crew initiated an evacuation via slides as a precautionary measure.
• Some passengers attempted to retrieve their luggage during the evacuation, which delayed the process.
4. Emergency Response:
• Emergency services promptly arrived to assist with the evacuation and ensure the safety of all occupants.
Initial Findings
1. Weather Conditions:
• Strong winds and a wet, slippery runway contributed to challenging landing conditions.
• These factors increased the risk of reduced braking efficiency.
2. Landing Performance:
• Eyewitness accounts suggest the aircraft touched down later than the optimal point on the runway, reducing the available stopping distance.
3. Passenger Behavior:
• Some passengers attempted to retrieve luggage during the evacuation, highlighting the importance of reiterating safety instructions during emergencies.
Safety Risks Identified
1. Runway Conditions:
• Wet and slippery runway surfaces can significantly impair braking performance, particularly in adverse weather.
2. Late Touchdown:
• Landing beyond the designated touchdown zone increases the likelihood of overrunning the available runway length.
3. Passenger Compliance:
• Passengers retrieving luggage during evacuation can hinder safety procedures and delay response times.
Recommendations
1. Runway Surface Maintenance:
• Ensure effective runway friction management during wet and adverse weather conditions.
2. Enhanced Pilot Training:
• Reinforce training for operations in challenging weather conditions, emphasizing the importance of accurate touchdown points and go-around decision-making.
3. Passenger Safety Protocols:
• Increase passenger awareness of evacuation procedures, emphasizing the dangers of retrieving personal belongings during emergencies.
4. Operational Coordination:
• Improve coordination between airport authorities and airlines to mitigate risks associated with adverse runway and weather conditions.
Safety Lessons
This incident underscores the critical importance of effective runway surface management, precise landing performance, and passenger compliance during emergencies. Despite challenging circumstances, the crew’s decision to evacuate ensured the safety of all on board. The event highlights the value of robust operational and training protocols to manage such situations.
