FAA Ground School Practice Test

Who is primarily accountable for the airworthiness of an aircraft?

1. Manufacturer

2. Pilot in command

3. Owner or operator

4. Maintenance facility

The correct answer is: Owner or operator

The owner or operator of an aircraft is primarily accountable for its airworthiness. This accountability arises from regulatory requirements and the responsibilities outlined in aviation regulations. The owner or operator has the ultimate duty to ensure that the aircraft is in a condition for safe operation and has undergone the necessary maintenance checks and inspections. While the manufacturer plays a role in ensuring an aircraft meets certain safety and performance standards upon delivery, and the pilot in command is tasked with conducting pre-flight checks and ensuring the aircraft is fit for flight, the long-term responsibility for maintaining airworthiness lies with the owner or operator. They are responsible for ensuring that all maintenance is performed according to the regulations and that the aircraft is operated in compliance with all applicable FAA rules and guidelines. Additionally, maintenance facilities contribute by performing necessary repairs and maintenance; however, they do so under the authority and oversight of the owner or operator. Therefore, the comprehensive responsibility for ensuring continued airworthiness resides with the owner or operator.
