Am I missing something here?
Since 28 Sept 2005, all JAR Operators have to have a Continuing Airworthiness Manager ("CAM") in order to comply with EASA Part M Subpart G. The emphasis being on the management of airworthiness rather than the commercial aspects.
Part-M Subpart G will in the near future affect all aircraft operators, at present it only affects those AOC operators aircraft on public transport C of A. The net effect is that there will be a mandated interface between an operator and a maintenance organisation with the CAM performing most of the functions proposed by Helicopterhelp.
The CAM has to be acceptable to the national authority and the simple fact is that if an Operator does not have that expertise "in-house", then they must contract it in.
It seems to me that Helicopterhelp already has a ready made market, fortunately for him, mandated by regulations, assuming he is acceptable to the authority.
