  Chapter 11: Helicopter Emergencies and Hazards › System Malfunctions › Antitorque System Failure

  following the manufacturer’s recommendations regarding operating limits and procedures and periodic maintenance and inspections, many system and equipment failures can be eliminated. Certain malfunctions or failures can be traced to some error on the part of the pilot; therefore ... appropriate flying techniques and use of threat and error management may help to prevent an emergency Antitorque System Failure Antitorque failure usually falls into one of two categories. One is failure of the power drive portion of the tail rotor…

  Chapter 11: Helicopter Emergencies and Hazards › Recovery Technique (Uncontrolled Right Yaw) › Main Drive Shaft or Clutch Failure

  Main Drive Shaft or Clutch Failure The main drive shaft, located between the engine and the main rotor transmission, provides engine power to the main rotor transmission. In some helicopters, particularly those with piston engines, a drive belt is used ... instead of a drive shaft. A failure of the drive shaft clutch or belt has the same effect as an engine failure because power is no longer provided to the main rotor and an autorotation must be initiated. There…

  Chapter 11: Helicopter Emergencies and Hazards › Recovery Technique (Uncontrolled Right Yaw) › Governor or Fuel Control Failure

  Governor or Fuel Control Failure Governors and fuel control units automatically adjust engine power to maintain rotor rpm when the collective pitch is changed. If the governor or fuel control unit fails, any change in collective pitch requires manual adjustment ... throttle to maintain correct rpm. In the event of a high side failure, the engine and rotor rpm tend to increase above the normal range due to the engine being commanded to put out too much power…

  Common Errors 1. Failure to use sufficient proper antitorque pedal when power is reduced. 2. Failure to stop all sideward or backward movement prior to touchdown. 3. Failure to apply up-collective pitch properly, resulting in a hard touchdown. Failure ... touch down in a level attitude. Failure to roll the throttle completely to idle. 6. Failure to hover at a safe altitude for the helicopter type, atmospheric conditions, and the level of training/ proficiency of the pilot. 7. Failure…

  Chapter 3: Identifying Hazards & Associated Risks › Leading Accident Causes

  general aviation fatal accidents include loss of control in-flight (LOC-I), controlled flight into terrain (CFIT), system component failure of the powerplant (SCF-PP), and fuel-related issues. These causes often signify the final result of a chain ... Examples of loss of control scenarios include continued VFR into IMC, wake turbulence upsets, thunderstorm encounters, instrument failure, improper aircraft loading, loss of outside references during flight at night or over water, and conditions that exceed the pilot’s capability…
