Even after MOSIAC the LSRI course is still very much relevant. MOSAIC didn’t eliminate it — it made it more useful.
It’s now the primary path for non-builders to legally inspect their own aircraft.
I've not met him but his name is well known in the Lancair community. LOBO has been around for decades. While I'm not a member of LOBO I did receive email from LOBO announcing they have been approved for providing LSRI courses. If I had not already completed the Rainbow course I likely would have looked into the LOBO course primarily due to the convenient location for me.
I met Matt in the LSRI course that we attended back in February which was put on by Mike Huffman just outside of Atlanta. During the course, Matt was inquiring what it would take to be able to put on such a training... since the Lancair group by themselves has quite a demand. It appears that he was successful in getting the ability to provide the training. He emailed out a link yesterday to sign up for 2 courses and they filled up quickly. He also indicated that they are looking at another June date in Florida and an option in California. So if interested, I would go to the Lancair Owners and Builders Organization (LOBO) and inquire.
