Accident to the Cessna T303 registered HB-LUV on 04/12/2020 at Annecy-Meythet

The pilot, in cruise flight and approaching Annecy-Meythet airport, was informed by the
Chambéry controller of the weather conditions, of the presence of slush on the runway and of an
average braking coefficient. He was cleared to join the RNP Z procedure for runway 04. He started
the descent late. The Annecy-Meythet controller cleared him for landing and informed him that
the runway was wet. The pilot continued the descent, the final approach and decided to land
although the aeroplane was not stabilised, either in terms of speed or on the approach path. The
aeroplane touched down near the runway mid-point at 119 kt, more than 30 kt faster than the
speed recommended in the Flight Manual. The presence of water on the runway, the high speed
during the landing and the pilot’s braking action resulted in a hydroplaning phenomenon which
made braking almost ineffective, with the aeroplane’s speed decreasing only slightly. The pilot did
not manage to stop the aeroplane before the end of the runway. The aeroplane struck the blast
deflector embankment at the end of the runway, crossed the road which runs alongside the
airport and came to a stop next to it.
