Circumstances:
Crew was performing a training flight with touch and goes in the zone of Maadhiggaru Falhu, South Male Atoll. Following a heavy landing, aircraft came to rest and sunk for few metres. Both pilots were uninjured and the company tried to recover the aircraft without success. During salvage operation, aircraft was also damaged. Eventually, it was decided it was damaged beyond repair.
Probable cause:
Impact with a high swell during landing followed by a high bounce and hard landing resulting in both float attachments being damaged and detached with a major structural damages. Major contributing factor was higher than normal touch down speed due to abnormal landing configuration.
Contributing factors:
- Selection of inappropriate landing site (channel) and landing direction (tail wind) based on surface conditions present at that time,
- Simulation of multiple emergencies,
- Abnormal landing configuration (flaps at zero) for single engine landing,
- Time pressure to complete the training and return to commercial operations.
