Sikorsky Aircraft Corporation Issues Airworthiness Directive for Certain Helicopter Models

Sikorsky Aircraft Corporation is issuing a new airworthiness directive for its Model 269A and 269B helicopters, requiring regular inspections and lubrication of the tail rotor driveshaft splined fittings to prevent potential failure and loss of control. The directive follows a report of the driveshaft disconnecting due to splined coupling deterioration.
