On 30 August 2018, a Boeing 747-400F making a crosswind landing at Hong Kong which was well within limits veered and rolled abnormally immediately after touchdown and runway impact damaged the two right side engines. The Investigation found that the flight was an experienced Captain’s line check handling sector and concluded that a succession of inappropriate control inputs made at and immediately after touchdown which caused the damage may have been a consequence of the Check Captain’s indication just before touchdown that he was expecting a landing using an alternative technique to the one he was familiar with.
Description
On 30 August 2018, a Boeing 747-400F (N415MC) being operated by Atlas Air on an international positioning flight from Dubai Al Maktoum International to Hong Kong as GTI 8086 during which a revalidation line check was being conducted veered abruptly away from the runway centre line shortly after touching down in a crosswind following a day VMC approach and both right side engines were damaged by runway contact before normal control was regained and the taxi in completed. Damage to the inlet cowl, fan cowl, reverser translating cowl drain of both right hand engines was subsequently found such that all these parts needed to be replaced.
Investigation
An Investigation into the Serious Incident was carried out by the Hong Kong Air Accident Investigation Authority (AAIA) in accordance with Annex 13 principles. Relevant data was recovered from both the CVR and the SSFDR. Relevant airport CCTV and ATC data was also reviewed and of assistance.
The 52 year-old Captain in command of the flight, who was acting as PF and occupying the left hand seat, had a total of 5,223 flying hours experience with Atlas Air, all but 23 of these hours being on type. The 58 year-old Check Captain had a total of 16,000 flying hours experience with Atlas Air of which 7,600 hours were on type. Both of these pilots held FAA-issued ATPLs. A Relief First Officer and an ‘operational experience student’ were occupying the flight deck supernumerary seats. During the cruise part of the eight hour flight, the Check Captain took a rest break but the Captain on line check did not, subsequently stating that he had not needed one as he had been “good to continue flying”.
