Description

On 18 December 2018, a Boeing 787-9 (ET-AUP) being operated by Ethiopian Airlines on a scheduled international passenger flight from Oslo to Addis Ababa as ETH175 and due to make an intermediate stop at Stockholm was taxiing into a remote stand to be de-iced prior to departure when it collided, in normal night visibility, with a lighting mast. The lighting mast was damaged to the extent that it required replacement and the collision caused significant damage to the right outer wing of the aircraft but there was no resultant fuel leak.

Investigation

The Accident Investigation Board Norway (AIBN) was not notified of the event, but after learning of it from media sources the following day, an Investigation was immediately commenced. The delay in reporting the accident and the failure to electrically isolate the two-hour CVR after it had occurred meant that its data were lost. However, relevant recorded ATC ground radar and communications data and CCTV pictures were available. It was deemed unnecessary to download data from the FDR.
