HE REPORTED THAT HE MADE A NORMAL APPROACH TO RUNWAY 27, AND FLARED HIGH BECAUSE OF THE DARKNESS, RESULTING IN A HARD LANDING. THE PLANE BOUNCED BACK INTO THE AIR, THE PILOT ADDED POWER AND MADE A GO-AROUND. HE SAID THE ENGINE VIBRATED BADLY, AND HE ASSUMED THE PROPELLER STRUCK THE RUNWAY, EITHER DURING THE HARD LANDING OR AS HE ADDED POWER.
