Subject: JabiruEngine-List: Re: Jabiru Muffler Failure

Dear Thread Friends, Last week after a short flight I was relocating my super 
duper homebuilt preheater under the cowl when I touched the left exhaust pipe 
and it moved. I removed the cowl and inspected and found two cracks had 
formed in the muffler, one above, one below the exit pipe from the welds. I removed

the muffler and then I saw what I am reporting as a failure. All the metal 
guts from the inside fell out. The metal screen inside the muffler had 
disintegrated into little chunks of steel. The inside part must not be made of

stainless steel ???? I fished them all out and made two gussets from 18 gauge 
stainless stock and TIG welded them to the exit pipes to strengthen them and repaired

the cracks. I did my 100 hour at Christmas, but missed any cracks, if they 
were there. What really jerks my chain is I have only 101 hours on the engine 
when the thing failed. I wonder what would have happened to my 3300, my plane and

my butt if a couple solid corner chunks stopped up an exit pipe in flight ??? 
All you Jab guys check your mufflers. Jab put out a SB some time back on the 
inlet pipe connectors cracking because the welds were MIG not TIG, but nothing

on the inside being eaten away, Bet regards, Bill of Georgia N505WP, 
601XL-3300
