It was a long time ago, but I questioned the factory on this. Since it was a long time ago, and said person no longer there, I will just let rest what they told me. It is a simple thing to follow the plans and no reason not too. Thanks to Vic for his post. Moving on now..... |
Bolt orientation
My DAR questioned the orientation of the bolt but I showed him in the plans how Van's had it oriented.

I dumped all of my kit hardware in trays and just picked what fit, using the plans to specify the type of hardware. Putting the wrong hardware in without checking the plans is a big boo-boo. :rolleyes: If original -6 builders simply went by bag labels there will be many bolts too short...:) |

If you found the wrong hardware, and called the factory, and they told you it was fine.... just sayin...., Is that still a big boo-boo? :rolleyes: hmmmm..... maybe. I love a mystery, and again, there is a reason Vic is finding this a common place that the hardware doesn't match plans and it isn't by chance. |

But I think it's because early -6 builders somewhat gave up on the plans by the time the wings got attached and simply used "standard" hardware without looking at the plans to see if a specific locations called for "special/different" hardware.. Did anyone really check bags of hardware that far along in the build process..:) |

The bolt specified in the plans for all RV kits is an AN5 with a castellated nut and cotter pin.
AN5 bolts are only used in a few places in an RV. The rear spar attach and the landing gear legs are the only ones I can think of right now so short AN5A bolts would have never been intentionally supplied. The RV-6A I completed in 1993 was supplied with castellated nuts and drilled AN5 bolts and they were called out in the plans. All new designs since the RV-6 have specified and supplied the same bolt (I think it is in the finish kit hardware). |

I am still dumbfounded why so many keep showing up, and I know what was supplied to me.... Others would have to intentionally order the wrong hardware as AN5A's typically aren't just laying around. Why would someone do that? No matter. If my kit was the only one in the fleet, others are just being careless. I didn't mean to derail Vic's safety post. It does'nt matter why the wrong hardware is being used. |
Not a shipment issue
OK, sorry, been busy all day and haven't had time to check this. The bolts are supposed to be drilled and castellated. Just yesterday I removed 2 more from the AFT spar in an RV-8 and they WERE drilled bolts(AN5) but yet had fiber nuts on them. I see many that way.
My guess is that at the airport when final assembly occurs, everyone forgets that it is supposed to be castellated and doesn't check because the plans are left at home. And I hear you on "they haven't moved so I leave them," but I don't think that is the right approach. My opinion. :) Vic |
