A pilot holding a Pilot (PG4) Licence with 1 years of experience whist flying at Ma On Shan at approximately 12-1400hrs on Monday 24th of November 2014.

Factors in this Incident:
Hard Landing
No Radio
Undershoot LZ

Event Description:

On my way back to the toplanding zone I did finally continue my flight as someone was taking off. Just after a massive sink occured. Estimating I could not reach the landing zone with my Glide Ratio,I made the decision to land on a clear way down of the ridge instead of trying to overfly the dense forest. Landing ok, packed everything and started to climb up.

Committee Response: (if any )

The pilot concerned is a visitor for overseas who was given a site briefing prior to flight. He understood the limitations of the site and chose to make a side landing on the grass spurs below the pyramid.

After the incident, pilot contacted by email to confirm details and check welfare.

It is apparent by photos and HK Observatory data that there still was lift available at the time of the incident.

Pilots need to remember that lift will vary throughout the day, in times of weak lift pilots who are low need to decide to land safely ANYWHERE on the ridge or COMMIT to landing in the LZ or at least put themselves in a position to glide to the LZ while looking for more lift.

Ma On Shan sometimes requires pilots to fly close to the hillside to be in the lift band. this requires pilots to fly close to eachother. please familiarise yourself with the RIGHT OF WAY RULES. If you get below the ridge the lift can be much less than level and above the ridge.

Good to hear that no injuries in this incident, but it highlights communication. Make a phone call to a flying buddy , or use your radio ( 145.9875 ) to advise of you status if you have problems. If you need help then tell someone, If you are OK then tell someone so as to avoid an unnecessary GFS call out with all the other staff having to come to the top of the hill.
