At the Fukuoka airport under strong wind, a veteran worker, who was checking the rock pin of the bulk cargo door of an MD'll airplane, fell down. In order to investigate the relationship of this fall accident and strong wind, a wind tunnel experiment and numerical computations using Fluent were carried out. Using a 1/100 scale model of the airplane, velocity distribution was measured by a hot wire probe. Calculating the three-dimensional inviscid incompressible flow, a flow field was obtained. It was shown that when there is a side wind against the airplane axis, a strong blow with complex vortices occurs on the leeward rear side of the fuselage. It is considered that such a strong wind broke down the worker's balance and led to the fall accident.
