This months Abbott aerospace newsletter has a interesting article on the current state of play with FAR23. The FAA issued an Accepted Means of Compliance with this in it:

"However, for means of compliance identified in the following list, Aircraft Type Code compliance matrix tables, which define applicability of the individual requirements of given standards, are not accepted in any ASTM F44 standard. Due to errors identified in the Aircraft Type Code compliance matrix tables, applicability of individual requirements of standards must be established with the Small Airplane Standards Branch."


It also seems to say, you can use amendment 63 (the current is amendment 64) except for loss of control and icing. I can't see much in the way of new aircraft coming through with the system being such a moving target.

I thought the whole thing was a mess from the get-go and never understood why the OEM's and alphabet organizations thought it was so great. The problem is that many of the requirements are poorly defined until the means of compliance are accepted, and the MOC are likely to take one right back to the previous system, or worse.

I think the persons supporting it were much like the CEO in the Abbott newsletter example, may we politely call them clueless rather than the persons at the coal face. The other driver appears to be moving the cost from the FAA to industry.
