    From: "John Wighton" <john@wighton.net>
    Brian, I disagree, an MPD is only issued when there is a serious concern over safety. To issue the MPD with a very brief (5 flying hours) incorporation requirement confirms there is a major issue and lives are at risk. Otherwise, why not make it a requirement for the next permit renewal? The engineering activity that reduces the risk needs to be compliant with the highest standards possible. By defining a solution and providing drawings, parts and instructions the LAA is now walking into a new room - one that has Liability Dept on the door and for the time being, "Also used occasionally for CAA audits". I was pointing out the sort of thing that LAA Engineering pulls us up on (meaning: applicants for Mods and new types, etc). When the 'missing data' might be irrelevant or numerically meaningless. In this respect, LAA Engineering needs to be demonstrating the process and engineering practice beyond reproach, as per its Exposition. And I still believe it is a solution that has not fully taken into account the build standard of most UK registered Europas - meaning the location having fasteners installed into is often 'busy' with fuel equipment, electrical wiring looms, microswitches, etc. This brings us back to the original comment. Is the supplied material PLA, ABS, Polycarbonate, something else? In 10 years time if the LAA supplied versions have fallen off, people might be asking what material should we not use? In addition to the above comment, I have since discovered that at least one LAA inspector (who looks after several Europas) had not had the MPD sent to him. I do hope that the additional missive has been corrected already. -------- John Wighton Europa XS trigear G-IPOD Read this topic online here: http://forums.matronics.com/viewtopic.php?p=504028#504028

    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.
