Well from what I have read it would appear that lots of people havent done the right thing and got the certification.  I was reading one of the jet events is having people on site to certify but, it would appear they are not holding everyone to the standard since a few people will be flying a certain jet that unless modified have a MAC of 27.5%.  I am working on my LMA1 stuff so I can certify people and I really wanted to know so I had the right idea. When I read the above reg, I read it as a must have and wanted to make sure. Thanks guys
