Under the DGCA’s audit framework, Level-1 findings relate to a more serious category of non-compliance and require immediate corrective action, and Level-2 to less serious deficiencies requiring corrective measures within a prescribed timeframe.The FAA performs air traffic control handoffs and assesses whether a foreign civil aviation authority complies with international aviation standards. The FAA last conducted an assessment in India in 2021. India currently holds Category 1 status under the FAA’s International Aviation Safety Assessment programme.The 2026 review comes against the backdrop of a series of incidents and operational problems over the past year, including the June 2025 Air India flight crash in Ahmedabad, which killed 260 people, and IndiGo's operational disruption in December 2025.
