You said, "Personally I wouldn't fly in a Jabiru-powered aircraft and I shudder to think I put my family and friends in one."
I accept what you say about Jabiru faults and seeing Stiff get off the hook as I believe he should have addressed problems. The actions of CASA are not appropriate, it does nothing to make Jabiru do anything. If you think this is the right action you may as well give up flying, do you know why Cessna stopped producing single engine aircraft in the early eighties ? It was a known problem with AD's yet litigation caused it from pilots who ignored it and failed to check.
I have seen pilots on many occasions do things to engines that I wouldn't do, so much so I would not get in any plane unless I know it history, maintenance, pilots and storage. Many Jabirus give trouble free operation but they are delicate and so are other engines. If you think a plane should put up with abuse then problems are sure to happen.
If someone flys a plane over weight regularly, high G turns, heavy landings, crabbed landings, steep climbs, idle descents, no warm up, stored long periods and engine not turned over.
I would not buy or fly a plane unless I knew it history. Jabiru are their own enemy at the moment but CASA are the enemy of the people as they have done nothing to address the problem merely caused inconvenience which could spread and destroy recreational aviation.
I fear structural failure more than anything, when I flew two stokes I was told " it's not IF but WHEN " a engine failure will happen. The Jabiru engine has been a great asset to the progression of light aircraft.
OPEN THE WINDOW AND TAKE A LOOK !
UL and D motor use Jabiru mounts, Rotec make after market parts, many flying schools use Jabiru, exported around the world. Etc, etc
CASA are completely out of control and are ready to wreck whatever they can get their hands on. Look at GA, where are all the flying schools, where are all the LAME and workshops ?
