摘要

These special conditions are issued for the Agusta S.p.A. (Agusta) Model AW139 and AB139 helicopters. These model helicopters, as modified by Agusta, will have novel or unusual design features associated with installing an optional SAR AFCS. The applicable airworthiness standards do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards the Administrator considers necessary to show a level of safety equivalent to that established by the existing airworthiness standards.
