Romeo Seahawk Airworthiness
LoneWolf - I am not suggesting it is in any way "un-airworthy". It is simply a case of there being very different standards that the MH60R and the MRH90 are certified to.
The Romeo must meet the "10 to the minus 6" standard inherent in MilSpec (and other standards) whilst the MRH90 is certified under FAR29, where the safety case is at the "10 to the minus 9" standard. MRH90 has exceeded the 10-6 standard in all cases, but was unable to meet the 10-9 case in some specific areas, thereby requiring dispensations, exceptions and some risk acceptance by the ADF Airworthiness Authority. Some of the Introduction Into Service heartache was due to this shortfall - it exceeded the standard by which the Romeo is being judged, but fell sort of FAR29 - a much more stringent standard. It is an interesting observation that there has been much focus on the shortfalls of the MRH90, but little discussion on the very concerning characteristics of the Romeo (e.g. No Floats - Navy helicopter? plus other capability shortcomings).
