What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Nose gear vibration landing. Typical 172. Porpoised using back yoke. Lost control veered off rwy. Nosed over snowba (.4)the pilot said that he applied back pressure to the yoke to reduce a nose wheel vibration during landing and the airplane began 'hopping.' The pilot also attempted to retract the flaps during the landing sequence in an effort to increase braking ability. During that time, the airplane drifted to the right, struck a snowbank, nosed over, and came to rest inverted. According to the pilot, 'the airplane drifted right and struck the snowbank, probably because I was reaching for the flaps.' The pilot had 100 hours of flight experience, 20 hours of which were in make and model. (-23) on landing roll out the nose wheel started to vibrate. The pilot use up-elevator and the aircraft was airborne then re-settled and he used hard braking, raised flaps lost directional control, veered to right and flipped over after striking snow on the right side of the runway. (The nose wheel had very little air in it. However, it tested OK/25 lbs. PSI).

THE PILOT USE UP-ELEVATOR AND THE AIRCRAFT WAS AIRBORNE THEN RE-SETTLED AND HE USED HARD BRAKING, RAISED FLAPS LOST DIRECTIONAL CONTROL, VEERED TO RIGHT AND FLIPPED OVER AFTER STRIKING SNOW ON THE RIGHT SIDE OF THE RUNWAY. (THE NOSE WHEEL HAD VERY LITTLE AIR IN IT. HOWEVER, IT TESTED OK/25 LBS. PSI).
