NLM13,. .. .The C441 is one of my favorite aircraft I have ever flown, a real pocket rocket, a sports car.. .. .Goes forever, they are most suited to flying east west directions, not that great at long north south flights.. .. .Never had any problems with the engines.. .. .Don’t know of any C441s in your part of the world, sure it was not a C425 (Conquest I) with the PT6 engines ?. .. .Did you catch the registration ?. .. .Z
