The way I read it.
You are all very naughty.
Planes have been falling down due to bad maintenance.(A little birdy told us).
We won't tell you which ones, or why, or how many, so just (Trust us).
We have employed people to draw pictures and graphs to show how naughty you are.
We are withdrawing all your L1 maintanence because you are not fit to hold a screwdriver.
you will need a L4 to sign off your maintenence before you can fly.
You have to do a course before you can add oil to your aircraft.
We will make it so difficult and expensive to fill out all the forms so you will give up and go away.
It will all be GA soon anyway.
==========================================================================================
The way it should read.
We have noticed a trend of engine failures in types XXX, YYYY.
Many XXX and YYYY failures had broken part ABCD.
Manufacturers indicates this is due to poor maintenance, and step abcd
in the engine service manual is not being done correctly.
Manufacturer XXX has supplied a video of how to do this step correctly, and what to look for.
If you are not comfortable, or able to do this, get someone to help who is, then send the
engine away to a repair facility.
RAAUS is providing maintenance courses for interested people on brand XXXX DD/M/YYYY at ???? for nominal fee $???
We will not take away your screwdrivers or threaten to ground you.
We understand that most members want to improve their skills and abilities, and do not need a cattle prod or
threats of grounding.
