 |
|
Started the repair on the bent/cracked engine mount and during the straightening process it broke off at the lower mid point at the intersection of tubes 7 & 6.On measuring the wall thickness it came to 0.035" and the drawings called for 0.058" [6-JE-1] This is now the second engine mount supplied with the use of incorrect thickness tubing/plates.What is happening to quality control?????? Jab USA has to get rid of the person welding these mounts.Lucky or unlucky as the case may be, if it wasn't for the nose wheel collapse the bloody engine might have fallen off.Cheers T87

How are they (Jab USA) about replacing factory defective parts?

I purchased a damaged 601xl earlier this year from a insurance company and have been repairing it for the last couple of months. It had suffered a bent nose gear also on one of it's first taxi test. It looked exactly like yours. The top of the firewall did not bend any, and the bottom was pushed back about 4 inches. The good thing is that the damage was contained to the firewall, cabin floor, engine mount, oil cooler, muffler and cowl. It did not get back into the wing spar carry through. It was fairly easy to fix the airframe. On my plane the nose gear was bent straight backward and up into the cabin floor.
My engine mount was bent also. I also found that it the 2 lower bars were built from .035 and not .058. I called and e-mailed the Zenith print to Jabiru USA. They informed me that they used .035 tubing for the entire mount. I also talked with Pete at the Zenith Fly-in this year and he confirmed that the built their mounts out of all .035. I replaced the 2 lower bars with .058 as the Zenith print called for. He also told me that there had been several prop strikes on the 3300, and all the engines where ok. He did say to be sure to replace the flywheel bolts as well as the bolts that hold the crank extension/prop adaptor to the crankshaft. The muffler is expensive, but it only takes a couple of hours to make a new "Skin" for it.
I almost have my plane back ready to fly.
