Special Conditions: Boeing Model 767-400ER; High-Intensity Radiated Fields

These special conditions are issued for the Boeing Model 767- 400ER airplane. This airplane will utilize new avionics/electronic systems that provide critical data to the flightcrew. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for the protection of these systems from the effects of high- intensity radiated fields. These special conditions provide the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
