If national authorities turn expression "recommended" into "mandatory", I

Welcome to Europe, where this is how EASA-rules are interpreted by most
national authorities' legal experts. Australia too, and I believe New
Zealand.

I live in EASA-world and our authorities did their "interpretation" process to these same l'Hotellier papers before accepting them as a part of my glider maintenance program. While letting 10 year replacement recommendation slip past their fingers, they did note that l'Hotellier annual measurement has to be made by aircraft mechanic with calibrated shop instrument, since papers did not specify that owner can do it (that is actually true and is not subject to interpretation). I still know of no owner who doesn't do it himself. That is the beauty of EASA, you write fancy documents (and pay for get them approved) and then continue to act like they don't exist at all. And no one gives a sh*t.
