## Abstract

These special conditions are issued for the Bombardier Model CL-600-2B16 (Bombardier) airplane. This airplane, as modified by Pro Star Aviation LLC (Pro Star Aviation), will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is a system that emits infrared laser energy outside the aircraft as a countermeasure against heat-seeking missiles. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
