The causes of helicopter accidents can be grouped into three major causal areas: Operational error, mechanical malfunction, and electrical malfunction. Within these broad categories, there are multiple underlying causes.
1. Operational Error. Although all three categories involve some degree of human error, operational error is the one where the human error is most direct and apparent. This human error can occur in flight planning, actual conduct of the flight, in training or in maintenance.
a. Failure to operate the aircraft in accordance with the aircrafts operational limitations.
b. Operating the aircraft in unsafe environmental conditions.
c. Failing to properly plan the flight.
d. Improper maintenance
e. Improper training of flight and maintenance personnel
f. Faulty manuals, training guides, checklists and operational procedures
g. Faulty oversight, auditing and review procedures
2. Mechanical Malfunction. A component of the aircraft fails or fails to function as intended. This can happen anywhere along the components life.
a. Improper design
b. Inadequate testing
c. Faulty manufacture
d. Inadequate quality control
e. Inadequate operational monitoring
f. Improper use
g. Poor maintenance
h. Inadequate lubrication or cooling
i. Improper installation
3. Electrical Malfunction Here, the electrical source stops working or one of its components has a malfunction.
a. The electrical source malfunctions
b. An electrical short occurs
c. An electrical component malfunctions
d. Inadequate design
e. Inadequate testing
f. Inadequate quality control
g. Inadequate operational monitoring
Each of these elements of the three major causal areas contains its own subset of individual factors as to exactly why and how it occurs. Sometimes these factors result in minor or no aircraft damage or injury, but all too frequently they cause great aircraft damage and personal injury, even death. One thing is true as to all causes: they are preventable.
