Who is responsible for the maintenance of the aircraft?

• A. Manufacturer
• B. Owner
• C. Operator
• D. Regulatory Authority

Answer: (B)

The maintenance of the aircraft falls primarily under the responsibility of the owner. The owner is accountable for ensuring that the aircraft is maintained in accordance with the applicable regulations and standards, which includes regular inspections, repairs, and adherence to manufacturers' maintenance guidelines.

While the operator may also have responsibilities related to the day-to-day operations and maintenance schedules, the ultimate financial and legal responsibility for the aircraft’s maintenance lies with the owner. This means that the owner must ensure the aircraft is airworthy and compliant with all relevant regulations, which often involves coordinating with licensed maintenance organizations and personnel to perform necessary work.

Regulatory authorities set forth guidelines and requirements for maintenance, but they do not perform the maintenance themselves. Similarly, manufacturers design and provide maintenance documentation but are not responsible for maintenance actions carried out on the aircraft in operational contexts.
