1999-07-05: The helicopter experienced a loss of tail rotor control. The pilot used a run-on landing technique to successfully land the helicopter on an oil service road. There was no damage to the helicopter and no injuries to the 8 persons on board. OPI - Maintenance and Manufacturing UPDATE M. & M. reported that the DOM of Delta Helicopters informed that the tail rotor pitch change housing failed. The housing is made out of aluminum with splines that mesh with other splines on a steel pitch change rod. The unit has to be disassembled to inspect this area every 1000 hours. It is unknown when this particular unit was last inspected. They are changing their inspection schedule to every 300 hours and will submit an SDR on this incident.
