Final answer:
The amount of time before an FAA complaint becomes "stale" depends on the circumstances. There is no set time limit for when a complaint becomes stale.
Step-by-step explanation:
The correct answer is D. It depends on the circumstances. The amount of time that must pass before an FAA complaint becomes "stale" varies depending on the specific circumstances of the complaint. There is no set time limit for when a complaint becomes stale. For example, complaints related to noise violations may have a shorter time frame for action compared to complaints related to safety concerns.
One example of a circumstance that could affect the time frame is if the complaint involves a potential violation of federal aviation regulations. In such cases, the FAA has the authority to take action based on the severity of the violation, regardless of how much time has passed since the complaint was made.
Therefore, it is important to consider the specific details and circumstances of the complaint to determine if it is still valid or has become "stale."
