Transport Airplane Directorate

Continued Operational Safety

• Print

• 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.
