• We monitor the transport category airplane fleet to ensure that airplanes continue to meet regulations and are safe throughout their operational life cycle.
  • We look for conditions that affect the safety of airplanes through surveillance, inspection, review, investigation, and analysis of service difficulties, incidents, and accidents.
  • If we identify an unsafe condition, we will:
    • Work with the manufacturers to mandate corrective action through airworthiness directives (AD),
    • Revise regulations/policy, or
    • Issue new regulations/policy.
  • We perform surveillance and oversight of production approval holders.
