The pilot was on initial takeoff climb at about 60 knots and 200 feet agl when he heard a loud noise from the vicinity of the tail section, followed by an immediate nose heavy condition. A right turn was initiated away from mangrove trees and the collective pitch was lowered. The helicopter started to turn to the right and collided with water and terrain in a nose down, right skid low attitude. Examination of the helicopter by an FAA inspector revealed the number five bearing, thomas coupling, and about 2 feet of the tail rotor driveshaft had separated and were not recovered.
Probable Cause: THE FAILURE OF THE NUMBER FIVE BEARING, SHAFT, OR THOMAS COUPLING FOR UNDETERMINED REASONS. CONTRIBUTING TO THE ACCIDENT WAS THE PILOT-IN-COMMAND'S DELAYED RESPONSE IN CONDUCTING THE EMERGENCY PROCEDURE BY NOT REDUCING THE THROTTLE TO IDLE POSITION, AND IMMEDIATELY ENTERING AUTOROTATION.
