Narrative:
On August 4, 1993, at 14:00 CDT (Central Daylight Time), a Bell 206B-3, N16814, sustained substantial damage during a forced landing near Pearland, Texas. The airline transport rated pilot and a mechanic aboard the helicopter were not injured. Visual meteorological conditions prevailed for the local maintenance check flight.

The Pilot/Operator report and statement submitted by the pilot reported that he performed the pre-flight, and after a 10 minute ground run was cleared for takeoff. During initial climb out, at approximately 200 to 280 feet above the ground (AGL), the engine made a noise and decelerated.

An auto-rotation was initiated to an open field. The pilot stated that "at about 30 to 40 feet I began a gentle deceleration and reduced my ground speed to about 0 at about 4 feet and waited for the aircraft to settle, then I began to cushion with collective." He further stated "the aircraft touched down and rocked forward and then back." During the backward movement, the pilot heard a loud bang. Damage to the helicopter included a severed outboard portion of the tail boom.

The mechanic reported in the enclosed statement that he was aboard the helicopter for a maintenance operational flight check following a turbine replacement. He further reported that the engine "seized at about 300 feet" above the ground. Examination of the engine by the operator and FAA inspectors (enclosed statement) indicated a lack of lubrication to the number eight bearing.

The NTSB determined the probable cause to be: The pilot's failure to maintain proper rotor RPM, the delayed flare, and improper touchdown. Factors were total failure of the power turbine due to oil starvation to the No.8 bearing assembly

US registration N16814 cancelled by the FAA as "Exported to Australia". It is believed that the helicopter became VH-LWN
