What type of maintenance involves major repairs and alterations?

• A. Line Maintenance
• B. Base Maintenance
• C. Routine Maintenance
• D. Preventive Maintenance

Answer: (B)

Base maintenance is responsible for conducting major repairs and alterations on aircraft. This type of maintenance typically takes place in a hangar or a maintenance facility equipped to handle significant work that may require extensive systems checks, disassembly, and reassembly of aircraft components. It is the stage where comprehensive inspections and modifications are performed, ensuring that aircraft are fully compliant with safety standards and airworthiness directives. Line maintenance, on the other hand, focuses on routine tasks such as daily inspections and minor repairs that keep the aircraft operational between flights. Routine maintenance encompasses regular checks and minor repairs, while preventive maintenance involves actions taken to prevent potential failures or issues but does not encompass major repairs or alterations. Therefore, base maintenance is the correct response because it aligns specifically with the need for handling substantial maintenance activities that exceed the scope of these other maintenance types.
