FAA Ground School Practice Test

Under what condition may a pilot operate an aircraft that is not compliant with an airworthiness directive?

1. When the aircraft has been modified

2. If allowed by the airworthiness directive

3. When granted a special waiver

4. During emergency situations only

The correct answer is: If allowed by the airworthiness directive

Operating an aircraft that is not compliant with an airworthiness directive is generally discouraged to ensure safety and regulatory compliance. However, there are specific circumstances outlined in the directive itself that allow for exceptions to this rule. The correct choice highlights that if an airworthiness directive allows for certain operations under specified conditions, a pilot may operate the aircraft in accordance with those conditions. This means there's recognition of the fact that not all airworthiness directives are absolute; some may provide stipulations that permit continued flight under controlled circumstances until compliance is achieved, or they may allow for certain operations despite the non-compliance. Understanding this reinforces the significance of thoroughly reviewing the conditions of any airworthiness directive. Pilots are responsible for staying informed about the directives that apply to their aircraft and understanding the allowances or restrictions therein.
