Air India grounds two pilots after its Hong Kong flight 'descended rapidly', probe ordered

New Delhi: Air India has derostered two pilots after their aircraft “descended rapidly and deviated significantly from the normal glide path" while approaching to land in Hong Kong on October 20. According to a “serious accident bulletin” issued by Hong Kong’s Transport and Housing Bureau (THB), this triggered “a ground proximity warning system alert. The crew recovered the aircraft at about 200 feet above mean sea level (AMSL) before performing a go around.”
A senior AI official said, “The pilots were derostered (taken off flying duties) and investigation was started immediately.” The incident happened when the Boeing 787 (VT-ANE) Dreamliner was approaching to land at Hong Kong International Airport (HKIA) with 197 passengers and 10 crew members at 6.14 am (local time) on October 20, 2018. The flight AI 314 had originated at Delhi.
“Before the approach to VHHH (HKIA), the crew had received cautionary information from the Hong Kong arrival Automatic Terminal Information Service (ATIS) regarding the possibility of Instrument Landing System (ILS) glideslope fluctuation. At 06:08:17 hours, the Air Traffic Control (ATC) further advised the crew of the possible glide path signal fluctuation. At 06:11:00 hours, ATC cleared the aircraft for the instrument landing system (ILS) approach for Runway 07R,”the preliminary report by THB says.
“During the approach, the aircraft descended rapidly, triggering a Ground Proximity Warning System (GPWS) alert on board the aircraft. The crew recovered the aircraft at about 200 feet above mean sea level, approximately 2.6 nautical miles from Runway 07R before performing a go around. The aircraft landed uneventfully on Runway 07R on the second approach,” it adds.
