Hong Kong’s Air Accident Investigation Authority is investigating an incident where an Etihad Boeing 787-9 deviated from the localiser course while landing.

The incident occurred on 7 September, 2019 at around 10:41 local time. The twinjet, registered A6-BLF (MSN 39651), was operating flight 834 from Abu Dhabi to Hong Kong, carrying 168 passengers and 11 crew members.

The aircraft was conducting an ILS approach into Hong Kong International Airport when it deviated from the localiser course.

It attempted to establish the localiser on Runway 25R after turning left. At around 15nm from the runway, the aircraft began deviating to the right of the localiser and descended below the minimum sector altitude of 4,300 ft.

Investigators note that the aircraft subsequently established the localiser course at about 11nm from the runway. The aircraft then landed without further incident or damage.

The authority has classified the incident as serious and will conduct a detailed analysis of the data and information collected.

It anticipates investigations to take up to 12 months.

Cirium fleets data indicates that Etihad took delivery of the GEnx-1B powered 787 in April 2016.
