Special Conditions; Maule Aerospace Technology, Inc. M-7-230, M-7-230C, and M-9-230 Airplane Models; Installation of Full Authority Digital Engine Control (FADEC) System and the Protection of the System From the Effects of High Intensity Radiated Fields (HIRF)

These special conditions are issued to Maule Aerospace Technology, Inc., for the Maule Aerospace Technology, Inc. M-7-230, M- 7-230C, and M-9-230 airplane models. These airplanes will have a novel or unusual design feature(s) associated with the installation of an engine that uses an electronic engine control system in place of the engine's mechanical system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards applicable to these airplanes. These special conditions were issued and effective in December 2003; however, they were inadvertently not published. This document is being published with the same effective date to correct that oversight.
