At the risk of extending this debate, this is not an MPD. An MPD is a
Mandatory Permit Directive, only issued by the CAA. What has been issued
is an Airworthiness Information Leaflet which references a Class A
Modification. The definition of Class A is that it is considered mandatory
by the LAA.
If you have concerns or questions regarding the Mod why not pick up the
phone and discuss it with Andy? We are all on the same side when it comes
to keeping us safe.
