Certification costs - Bell412
Does anyone know where I would be able to find information on the costs associated with recertification of a Bell412??? Any info would be much appreciated!
FYI This is for a handling qualities module I am studying at The University of Liverpool for a Masters in Aerospace Engineering. We have designed a handling control system for a Bell142 in an EMS role (somewhat relevant to a recent media frenzy...), and it is my responsibility to conduct the feasiblity report. The economics is the hard part; can't find any info related to certification costs, not even accounts of historical cases or for similar rotorcraft.
Any thoughts guys?
