An Air India Boeing 787-8, registration VT-ANE performing flight AI-314 (dep Oct 19th) from Delhi (India) to Hong Kong (China) with 197 passengers and 10 crew, was on the ILS approach to Hong Kong’s runway 07R at about 06:14L (22:14Z Oct 19th), ATIS had warned of possible glideslope fluctuations, when the aircraft descended to 200 feet AGL about 2.6nm short of the runway until the EGPWS issued a warning. The crew initiated a go around, positioned for another approach and landed safely on their second approach to runway 07R.

Hong Kong’s Air Investigation Authority (HKAIA) released their preliminary report stating: “Before the approach to VHHH, 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. 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.”

The HKAIA reported the captain (ATPL, 1750 hours on type) was pilot flying, the first officer was pilot monitoring.
