Nord-Flyg flight NEF021 descended below the approach glide slope during an approach to runway 21 at Mariehamn Airport (MHQ/EFMA). The airplane landed normally but the Finnish AIB decided to launch an investigation into the incident.
Preliminary results were issued on March 9:
- The event took place in night flight conditions.
- The aircraft was approaching Mariehamn airport from the east.
- The approach was at times a much steeper and the plane was banking at an angle of up to about 50°.
- The aircraft flew to a lowest altitude of about 50 m at three kilometers from the runway. Normal height at that distance is about 150 meters.
Probable cause and contributing factors:
The serious incident was caused because the captain of NEF021 continued the approach in a situation which did not meet the requirements of a successful approach and landing. This degraded the flight crew’s situational awareness to the extent that the captain flew the aircraft into an unusual attitude and the crew lost control of the aircraft. This resulted in the risk of colliding with terrain.
As regards contributing factors Crew Resource Management was poorly handled, and the captain did not comply with the Company’s Operations Manual. Additionally, the crew did not follow the instrument approach procedure and ignored the warnings of the Ground Proximity Warning System.
