The NTSB's probable cause their words, unchanged
improper maintenance inspection of the tail rotor by maintenance personnel and improper preflight inspection of the tail rotor by the pilot, which resulted in worn elastomeric bearings being continued in service, resulting in failure of the tail rotor assembly, and damage to the helicopter during a hard landing.

The NTSB's narrative final · quoted from the NTSB record
The pilot said he had been flying the helicopter at an altitude of about 500 feet, 100 knots indicated airspeed, and 65 to 70 pounds per square inch torque, when he felt a high frequency vibration through the antitorque pedals. He said the vibration dissipated but soon began again, and became excessive with 'strong' forces in the pedals. The forces were soon followed by a loud 'bang' and the aircraft yawed violently to the right, and the nose pitched down. He said the antitorque pedals had no effect, so he lowered the collective control and applied aft cyclic control input to the stop the yaw, and level the aircraft. He said the yaw rate slowed, but did not stop, and at about 70 to 80 degrees of right yaw, he reduced the throttle in an attempt to further reduce/control the yaw condition, and the aircraft yaw stopped. He was then able to execute an autorotative landing to an open field. The on scene examination of the aircraft showed that the stabilizer, as well as an 18-inch section of the hollow portion of the tail had separated from the aircraft in flight. The 90-degree gearbox also partially separated from the aircraft, and was only held by one remaining bolt, and there were contact marks and paint transfer signatures, consistent with those from multiple tail rotor blade strikes at the fracture point. The aft 6 inches of the tailboom with attach points, tail rotor gearbox, and tail rotor assembly were retained for metallurgical examination. The examination revealed that the fractured tail rotor gearbox studs were fatigue failures. In addition, both elastomer bearings in the tail rotor drive fork were examined, and were found to have failed due to fatigue.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number MIA00TA200.
