LDA approach missing

I'm hoping to do some IFR currency training today if the winds don't interfere and one of the approaches the instructor said to review is the VNY LDA-C.  The approach isn't in the IFD database (at least not in the trainer) and although I've never flown a LDA, I don't see anything unique about it for why it wouldn't be in the database.  I was able to create the approach easy enough by punching in the individual waypoints for situational awareness.  The approach uses VLOC for final navigation so I don't need to worry about not pulling it from the database, but I'm curious as to why it's not in the database.

During my IFR training I recall flying the LDA-C into KVNY and I seem to recall the approach not being in the database for my Garmin 430W either.
