What should a pilot do if they are unsure why the FAA inspector is contacting them?

When a pilot is unsure why the FAA inspector is contacting them, the most appropriate course of action is to ask the inspector for more information before responding. This approach allows the pilot to gain clarity about the nature of the inquiry or concern the FAA inspector may have. Understanding the specific context can help the pilot address any issues more effectively and demonstrate a willingness to cooperate while also protecting their rights.

By seeking clarification, the pilot can ensure that they are providing accurate and relevant information rather than potentially disclosing unnecessary details that might complicate the situation. This proactive communication can also help build a cooperative relationship with the inspector, which is essential in regulatory environments.

The other options are not advisable as they either involve making assumptions or can lead to misunderstandings and further complications. Providing unnecessary details or claiming ignorance can increase the risk of miscommunication or raise red flags, while refusing to answer questions could create the impression of non-compliance or evasiveness.
