  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…

  accelerate to the normal climb speed. Then, reduce power to the normal climb power setting. Common Errors 1. Failure to perform, or improper performance of, a high or low reconnaissance. 2. Approach angle that is too steep or too shallow ... existing conditions. Failing to maintain proper rpm. Failure to consider emergency landing areas. Failure to select a specific landing spot. 6. Failure to consider how wind and turbulence could affect the approach. 7. Improper takeoff and climb technique for existing…

  Chapter 7: Automation & Flight Path Management › Failure to Anticipate, Act, & Verify

  Failure to Anticipate, Act, & Verify Automation offers increased safety with enhanced situational awareness. However, these systems make it possible for a pilot to become complacent, unprepared, or lose situational awareness. If this occurs and an unexpected change in flight plan ... crew was unexpectedly cleared for an approach, lost situational awareness, and crashed into mountainous terrain. The accident summary cites failure of the flight crew to revert to basic radio navigation at the time when the FMS-assisted navigation became confusing…

  Chapter 3: Induction & Exhaust Systems › Reciprocating Engine Exhaust Systems › Muffler & Heat Exchanger Failures

  Muffler & Heat Exchanger Failures Approximately half of all muffler and heat exchanger failures can be traced to cracks or ruptures in the heat exchanger surfaces used for cabin and carburetor heat sources. Failures in the heat exchanger surface (usually ... outer wall) allow exhaust gases to escape directly into the cabin heat system. These failures, in most cases, are caused by thermal and vibration fatigue cracking in areas of stress concentration. Failure of the spot-welds, which attach the heat…
