A Boeing 747-200 cargo plane, JA8191, sustained moderate damage in a tailstrike accident on takeoff from Tokyo-Narita Airport (NRT), Japan. There were no injuries to the four crew members. Nippon Cargo Airlines flight 62 took off from runway 34L at Tokyo-Narita on a cargo flight to Anchorage (ANC), USA. During the takeoff, the aircraft’s aft fuselage contacted the runway surface and the aircraft sustained moderate damage, but continued its takeoff and became airborne. Thereafter, the aircraft returned to Narita Airport and landed. PROBABLE CAUSE: “In this accident, while the aircraft was taking off from Narita Airport, it is estimated that liftoff was delayed due to rotation being initiated at lower than the appropriate speed, and that the lower surface of the aft fuselage contacted the runway surface, causing it to be damaged. It is estimated that the following factors were involved in the rotation being started at lower than an adequate speed: (1) When the FE prepared the data card, he did so reading the takeoff speeds and target pitch attitude from the chart corresponding to the aircraft’s zero fuel weight instead of its takeoff weight by mistake and further, because he did not reconfirm, he did not realize his mistake. (2) The captain, the trainee pilot acting as PNF, and the first officer had no doubts about the speed values on the data card prepared by the FE. (3) The preparation of data cards at NCA is done solely by the FE, and other crewmembers are not involved in their preparation or reconfirmation.”
