Private Pilot Private Practice Exam

The correct answer focuses on the necessity of having a qualified pilot conduct a test flight after significant alterations have been made to an aircraft. When alterations impact flight operations significantly, it is crucial to ensure the safety and airworthiness of the aircraft before returning it to service.

A test flight is conducted to evaluate the alteration's effects on performance and handling characteristics. A qualified pilot, being knowledgeable about the aircraft and equipped to assess any operational changes effectively, ensures that any risk factors are identified and managed. This step is fundamental in maintaining aviation safety standards and complying with regulations following substantial modifications.

Considering the context of the other options, while a pilot can assess the need for a test flight, it is not merely a subjective judgment but rather a procedural requirement dictated by safety practices and compliance with aviation regulations. Reporting to the FAA is typically required for major alterations but may not always necessitate a flight test if the changes are not deemed significant. The last choice mentions that no action is required for minor alterations, which further emphasizes the distinction between minor and significant changes that might not necessitate the same level of scrutiny or testing.
