What happened
While operating in adverse weather conditions, the pilot was established in the traffic pattern for landing on runway 26 at an alternate airport. The pilot reported receiving ATIS information 'India.' At the time of the approach, winds were recorded from 280 degrees at 11 knots with gusts reaching 18 knots. Air traffic control advised the pilot that the wind was from 290 degrees at 12 knots.
As the aircraft approached touchdown, the pilot reported a sudden decrease in airspeed of 10 knots. This resulted in a hard landing on the nose landing gear, which caused the aircraft to begin porpoising. The pilot did not initiate a go-around procedure by applying power. During the second touchdown, the nose landing gear collapsed.
