AAIB investigation to Boeing 737-8Q8, YR-BMF
Tailstrike on takeoff, Birmingham Airport, 28 July 2018.
Summary:
Prior to departure the aircraft’s takeoff data was calculated on an electronic flight bag (EFB) using its zero fuel weight (ZFW) instead of its takeoff weight (TOW). The pilots did not crosscheck or independently calculate the data. During the takeoff the aircraft suffered a tailstrike.
Despite ATC asking the pilots if they had a tailstrike, the error subsequently being noticed in the EFB and a member of the cabin crew hearing a strange noise during the take off, the tailstrike checklist was not actioned. The aircraft continued to its destination and, after landing, damage was discovered on the underside of the aircraft.
The operator has published a safety notice reminding pilots of its procedures when calculating takeoff performance and to refer to the checklist after an unusual occurrence.
