The approval of this change in Type Design applies to the basic H-295 only. The installer must determine whether this design change is compatible with previously approved modifications. If the holder agrees to permit another person to use this certificate to alter a product, the holder must give the other person written evidence of that permission. This determination should include consideration of significant change in weight distribution such as an increase in the fixed disposable weight in the fuselage.
