Narrative:
UNI Air flight 9091, an ATR 72-600 (72-212A), registration B-17010, departed Taipei-Songshan Airport at 09:27 local time, on a flight to Nangang Island. The copilot was Pilot Flying.
The flight was cleared for an RNP approach to runway 21. At 10:05 the aircraft was at 958 feet and passed the minimum descent height. The flight reported runway in sight and continued the approach.
At a distance of 1.5 nm from the runway threshold, the aircraft dropped below the glide slope.
At 10:06:14, at about 0.15 nm from the runway, the pilot called "come and go around", and two seconds later, the autopilot was disconnected. Four seconds later the main landing gear and tail skid struck the top of a concrete perimeter wall
The flight crew continued the missed approach procedure and radioed that they suspected damage to the nose landing gear.
At 10:08, the flight crew requested to return to Songshan Airport.
Suspecting damage to the nose gear, the flight crew first flew a low pass over runway 10 at 10:45 hours. The tower controller at Songshan Airport reported observering damage to the right main gear wheels. The pilot decided to fly the traffic circuit with the gear down and landed on runway 10 at 11:07 hours.
