Yes it is interesting, but not unusual for SA. Its no doubt a former military aircraft. It seems to have been blessed by the CAA.
Making money in Aviation is the bottom line, so the owners of the aircraft will do whatever is necessary to make Rand from JP-4. I know I would. Im sure they will only have a problem if they ball one up.........thats the way it usually hapens.
If someone really wished to stir the pot. They would no doubt contact Bell Helicopters, and Im not talking Bell in SA.. Things would roll down hill from there for sure.
Other than that, you pays your money and you takes your chances.
