## Analysis

AT THE END OF ONE LEG OF A SOLO CROSS-COUNTRY FLIGHT THE STUDENT PILOT EXPERIENCED A HARD LANDING WHICH RESULTED IN A PORPOISE ON THE RWY. THE PILOT DID NOT REALIZE THE SEVERITY OF THE INITIAL BOUNCE AND TRIED TO RE-FLARE THE AIRCRAFT WITHOUT ADDING POWER. THE AIRCRAFT BOUNCED A SECOND TIME AND ON THE THIRD BOUNCE THE NOSE GEAR COLLAPSED. THE PILOT REPORTED THAT DURING THE APPROACH SHE WAS DISTRACTED WITH THE THOUGHT OF WHERE SHE WOULD PARK SO THE AIRCRAFT COULD BE RE-FUELED.
