The FAA's summary their words, unchanged
These special conditions are issued pursuant to 21.16 and 21.101 of the Federal Aviation Regulations (FAR) for the Boeing Model 767 series airplanes with PW4000 series engines. The airplanes with these series engines will have novel or unusual design features associated with the installation of the digital electronic propulsion control system for which the applicable airworthiness regulations do not contain adequate or appropriate safety standards for protection from the effects of lightning, the susceptibility to external radio frequency (RF) energy sources, and the overall propulsion control system integrity. These special conditions contain the safety standards which the Administrator finds necessary, because of these added design features, to ensure that the functions of these systems, which are critical, are maintained.
