To the attention of operators of GA helicopters

     Graph with serial numbers of helicopters subject to the IAC Aviation Register type Certificate was removed from data sheets that eliminated time delays when registering prototypes.
     Type design of helicopter certified (validated) by the IAC Aviation Register is issued as a separate document which simplifies the potential operator to obtain complete reliable information on this type of helicopter. 
        Operating conditions limitations that are not dictated by the content of Aviation Regulations but based on expert analysis are eliminated from data sheets and helicopters maintenance documentation.
