摘要

1999年7月16日,一架波音737-800在最后进近准备着陆时遭遇了一次大雷击。机身结构损坏主要表现为大间距铆钉和相邻Alclad 2024-T3机身蒙皮熔化或部分熔化。损坏范围限制在0.25英寸。(6.4 mm)半径在受影响的铆钉周围。修复过程包括去除局部受影响的材料,并添加皮肤加倍剂,以将飞机结构恢复到最初设计的状态。简要描述了损伤特征。

Analysis of Aircraft Damage from a Lightning Strike
On 16 July 1999, a Boeing 737-800 on final approach for landing sustained a major lightning strike. Damage to the fuselage structure primarily was in the form of melting or partial melting of widely-separated rivets and adjacent Alclad 2024-T3 fuselage skin. The damage was confined to a 0.25-in. (6.4-mm) radii around the affected rivets. The repair process involved removal of the locally-affected material and addition of a skin doubler to restore the aircraft structure to the originally designed condition. Damage features are described briefly.
