Any discrepancies or findings identified during these surveillance activities are promptly communicated to the respective airline to undertake corrective rectification action. Moreover, in some cases where violations are detected, the DGCA follows a rigorous enforcement process in accordance with established procedures. This may involve issuing warnings, implementing suspensions or cancellations of Approvals, and even imposing financial penalties on the individuals or organizations involved. The enforcement actions taken by the DGCA are aimed at ensuring compliance and maintaining the highest standards of safety and regulatory adherence within the aviation industry.
