An aviation inspector performs many functions to ensure the safe transportation of airline passengers. He or she investigates accidents and equipment failures, examines aircraft, air traffic controls, navigational aids, and communications equipment, and suggests repairs when necessary. He or she analyzes safety procedures and reviews maintenance procedures to make sure that airports and aircrafts are in compliance with federal safety regulations. Aviation inspectors also perform the following duties:

• They are responsible for issuing pilots' licenses.

• They inspect aircraft doors for safety and security.

• They evaluate the work of aircraft mechanics to ensure adherence to standards and procedures.

• They test aircraft meters, gauges, and other instruments for evidence of problems.

• They check the tires, landing gear, wings, fuselage, and engines for wear, damage or the need for repairs.

• They review flight logs and maintenance records to ensure that servicing was performed at the necessary intervals.

• They suggest the repair or replacement of aircraft equipment.

• They are responsible for approving or denying certificates of airworthiness.

• Considering their knowledge of operating conditions and aircraft improvements, they can recommend changes to policies, standards, rules and regulations.

• They maintain detailed records regarding inspections, repairs, investigations, and reports in order to issue certifications.

• They attempt to determine the causes of air accidents.

• They conduct flight test programs under a variety of conditions to test instruments, equipment, and systems.
