Here's what I'd like to do, hopefully someone tell me if it's possible. I've yet to run this by a Sport CFI, as I can't find one in my area, yet. My question(s) are regarding "what's already been proposed" in MOSAIC, so pretend it passes as is for my situation. I want to buy a experimental JMB VL-3 w/retractable gear, then find an "capable" Sport CFI and have him/her train me in my own plane, use it for the checkride, cross country etc.... just never use the retractable gear while being trained, either by disabling it, locking it in place or maybe even removing the fuse. Whatever method would be deemed "legally" acceptable, if any. I've read somewhere the retracts can be mechanically locked into place, for sure remove the hydraulic cylinders and cover the holes, JMB offers a kit to do this. Then, after attaining Sport Pilot certification, get the SP CFI endorsement for the retractable gear, and everyone is good to go? Is this currently doable now, or have to wait until MOSAIC is "law", or just train in it until MOSAIC, or fly with someone else as PIC, fly with gear locked until MOSAIC? ... The bottom line is I only want to buy 1 plane and be trained as a Sport Pilot to fly this plane. Any comments or advice, suggestions? Thankx in advance
