Air India has grounded two pilots after an aircraft they were flying "descended rapidly and deviated from the normal glide path" at the Hong Kong International Airport runway, news agency ANI has reported.

The aircraft had triggered a Ground Proximity Warning System alert, the agency adds.

The incident took place on October 20 when the plane was approaching to land at the at Hong Kong International Airport at at 6.14 am (local time). The Boeing 787 plane had 197 passengers and 10 crew members aboard.

"Before the approach to Hong Kong International Airport, 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," a priliminary report read.

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 report said. The aircraft landed "uneventfully on the runway on the second approach," it said.

A probe had been ordered into the incident by Chief Inspector of Hong Kong's Transport and Housing Bureau and the National Transportation Safety Board (NTSB) of the United States of America and the Aircraft Accident Investigation Bureau (AAIB) of India, representing the State of Design and Manufacture and State of Registry of the aircraft respectively.

In another incident in October, an Air India pilot and his co-pilot were taken off roster when the pilot flying the Boeing 737 hit a brick wall at the Tiruchirappalli International Airport in Tamil Nadu. The Dubai-bound plane had 130 passengers on board. And despite the audible and obvious collision, the pilot apparently saw no reason not to continue on, said reports.

Another failed landing due to deteriorating weather at New York's John F Kennedy International airport turned out to be a nightmare for an Air India pilot in September.

The Air India's flagship flight, AI-101, had 370 passengers on board. They had been flying for more than 15 hours on the non-stop service from New Delhi, among the longest flights in the world. Moments before touchdown, the tower at Newark Airport sounded out an alert and said AI-101 was flying too low on its approach. 90 seconds later, the big jet was on the ground, approximately 38 minutes after the in-cockpit crisis first occurred.
