WARNING:

People who fly should recognize that there are various types of risks are involved

in this activity; and they should take all precautions to minimize them, since they

cannot be eliminated entirely. The alternator is an important component of the

aircraft. An alternator failure could result in an unplanned landing or even more

severe consequences creating an unsafe condition that may result in death, serious

bodily injury, and/or substantial property damage. It is, therefore, essential that the

alternator is properly maintained according to the recommended service procedures

and monitored to detect impending problems before they become serious. Any

unusual operation should be investigated and corrected, as it may be a warning of

impending failure.
