A five-member audit team of the International Civil Aviation Organization (ICAO) was in India between November 6 and November 16 as part of its universal safety oversight audit programme.
The team appraised six different areas, including personnel licencing, airworthiness, operations, legislation and organisation.
The team members visited Chennai, Mumbai and that Civil Aviation Training College in Allahabad to inspect implementation of safety procedures laid down by the ICAO and India's aviation regulatory body Directorate General of Civil Aviation (DGCA).
The audit involved verification of response provided by the DGCA to certain protocol questions sent by the ICAO.
