## Abstract

These special conditions are issued for Learjet Model 35, 36, 35A, and 36A series airplanes modified by Elliott Aviation Technical Products Development Inc. These airplanes, as modified by Elliott Aviation Technical Products Development Inc., will have novel and unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. The modification incorporates the installation of an electronic flight instrument system (EFIS) for display of critical flight parameters (altitude, airspeed, and attitude) to the crew. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that provided by the existing airworthiness standards.
