Does the twin-jet Cri-Cri still exist or does someone need to build
one to get the Guiness mistake fixed?

Light Sport Pilot has the restrictions of no turbines and no twins,
however, Part 103 has no such restrictions - but 103 does have the fuel
limit of 5 gallons, speed limit of 63 mph and the weight limit of 254
lbs. Safety equipment can be added above and beyond the 254 limit
...like how about another 5 gallons of fuel please - for safety!

FAR Part 103:

Guiness World Record smallest jet, only cares about it being a "jet" and
"162 kg" max weight...

Now if you actually want to fly it (apparently Yawn doesn't), then you
can do the FAA paperwork for what classification you desire...

I will contribute to the cause, that has the current record holder
replaced...
