Lightning causes physical damage to the aircraft due to the direct attachment of the lightning channel and conduction of the current. Additional effects include bending, melting, burning, pitting and/or vaporization of the aircraft structure or components, magnetic pinching, shock wave and overpressure, explosion of fuel vapors, electric shock and flash-blindness, and residual magnetism. It also includes the currents and voltages directly injected in associated wiring and plumbing.
Lightning damage illustrates the importance of thorough inspections done by properly trained maintenance technicians utilizing specified tools and methods to detect the damage so that aircraft are returned to service and allowed to fly only in an airworthy condition.
