A Near-Death Experience
This was at my dad's work. They were moving an F-16 with a crane
when there was a loud pop. Naturally, they stopped the crane, and unnaturally a bunch of people started walking around the plane to figure out what had popped. Including roaming around beneath it. Nobody found anything, so everyone got back and they started moving the whole thing again. A second later, popoh****wham! F16 on the floor with a few million in damage to it. Turns out when they recently overhauled the cranes there someone ordered a wrong bolt--was off by one line in the chart. So the connection between the hook and the pulleys wasn't strong enough and gave way. They're extremely lucky the thing didn't fall on those idiots under it. At that time it was down to one half-sheared bolt holding up the whole weight. -- B.B. --I am not a goat! thegoat4 at airmail dot net http://web2.airmail.net/thegoat4/ |

Ok, I'm getting old and times might have changed since I was in the Army and used cranes. But back then, the fastest way to get a sargent's boot up your ass was to do something stupid safety-wise like walk under a load. Where were their heads at? The whole thing would have been a non-incident if they would have lowered the plane and inspected the rigging at the first sign of a problem. |

It's fortunate that nobody was hurt. This reminds me of the yokels at
Lockheed who removed bolts holding a $240 million satellite to its rotating support stand and forgot to tell anyone about it. Another crew came in the next day and, without checking, decided to tip the stand 90 degrees -- bam! http://images.google.com/imgres?imgu...lr%3D%26sa%3DG All in a day's work I suppose!

I think they are still working on the mess, and it may cost nearly as much as replacing the entire satellite to tear it down, send every part back to the manufacturer for a complete tear-down inspection and recertifying the component for flight, replacing the obviously damaged structural components, and then putting the whole thing back together. Obviously, Lockheed Martin is going to lose several hundred million $ on this incident. Jon |

Accidents can happen so easily. A twenty plus ton load dropped about a foot
to the deck of the truck trailer last week. The sling chain snapped a link. The trucker was crawling around underneath checking his trailer afterward :')) The guy on the pendant was standing on the deck about ten feet in front of the thing when it let go. I was behind a large frame a safe distance but did seethe flash of light as the link failed. No one was in line with the chain as it flew around. We have 23 more lifts like this one. We now have new half inch chain instead of the 3/8 which was maxed out between the two cranes. We also had been walking around grinding off weld scabs only a few minutes before it was located over the trailer. Randy "B.B." u wrote in message news This was at my dad's work.

This one is not quite along the same lines, but nonetheless a very
interesting item with potential deadly consequences. I work for a very large aircraft manufacturer. In the process of building widebody airplanes, the front and back body sections are joined to the center body and wing section in a huge jig called final body join. After the sections are slid together and aligned, there are a number of titanium temporary fasteners that are installed to keep anything from moving. It's called "pinning" Sixteen or so pins, I think. So, early one morning after an airplane had been joined and pinned, someone (well, the story seems to change slightly depending on who you hear it from!) decided to jack the tail up six inches. Okay, so here's a rather long airplane and the leverage exerted from about a hundred feet back on three varied aluminum alloy layers, none more than a quarter of an inch thick is pretty incredible. Can you imagine what happened next? Up until this point, I had never seen a bent titanium fastener of this type. Not just bent once, but dog-legged. Well, I'm told by those that were walking around at the time that it sounded like popcorn or .22 rounds going off, and these fasteners came flying out a rather great velocities. People were diving all over the place to avoid something they had no clue about. The skin material next to the holes was swaged/squashed up and/or pulled "long" and when the strain was too much, the "nuts" on the pins gave way, letting these things fly. The damage was so extensive they went ahead and finished building the plane, stuck together with a few hundred temporary bolts, then when done down the line, they pulled it aside and replaced several million dollars worth of skin panels and underlying structure. Pretty incredible what it looked like, being able to see all the way through the plane to the other side, with nothing but the skeleton seeming to hold it together.

They bolted it to the adapter, but didn't notice the adapter wasn't bolted to the turnover cart, after it'd been borrowed by the DMSP folks. Oops. Check out http://www.spaceref.com/news/viewpr.html?pid=15189 which has the final report. "We recommend ass beatings all around but it won't change a thing" "The Technician Supervisor even commented that there were empty bolt holes, the rest of the team and the RTE in particular dismissed the comment and did not pursue the issue further. Finally, the lead technician and the Product Assurance (PA) inspector committed violations in signing off the TOC verification procedure step without personally conducting or witnessing the operation. The MIB found such violations were routinely practiced." "The MIB finds the LMSSC system safety program to be very ineffective. Few resources are allocated to system safety, few requirements for safety oversight exist and little programmatic supervision was provided for the safety representatives." "Also, some team members were notified as late as quitting time the day before the operation that they were to perform the next day." Gee Golly!

If that's the tower that collapsed in Texas, a friend of mine, Cowboy was
his nickname, was one of the flyers, rest his soul. That was to be one of the tallest towers in the world, if I remember correctly.

Is this another 5mph bumper issue - I'd think a plane like the F-16 could be dropped 5' and not take it in the tires and shocks ?! I thought it was Aircraft Carrier rated ! I believe about the bolt - any day - that is critical today - and to many young people don't know or don't realize the life and death issue because.

Is it this one? http://www.hanessupply.com/images/RiggersPDF_200406.pdf No, but it has at least some information amongst the sales crap. I am confused, is that a sales brochure or a rigger's handbook? Looks like a little of both. Not the one I was thinking, but probably worth printing. Dave Hinz |

I put in "handbook riggers" (without quotes) and found it he http://www.sapsis-rigging.com/Mercha...gory_Co de=30 (watch the wrap on the URL) Probably other sources, but this is the first URL that google could find with a picture of it. Was a great book when I got it a dozen years ago, would surprise me if it's not still great. Dave Hinz |

"B.B." u wrote in news This was at my dad's work. They were moving an F-16 with a crane when there was a loud pop. Naturally, they stopped the crane, and unnaturally a bunch of people started walking around the plane to figure out what had popped. Including roaming around beneath it. Nobody found anything, so everyone got back and they started moving the whole thing again. A second later, popoh****wham! F16 on the floor with a few million in damage to it. Turns out when they recently overhauled the cranes there someone ordered a wrong bolt--was off by one line in the chart. So the connection between the hook and the pulleys wasn't strong enough and gave way. They're extremely lucky the thing didn't fall on those idiots under it. At that time it was down to one half-sheared bolt holding up the whole weight. I had a similar incident happen to me, albeit miniscule in comparison. I was trying to remove one of my upper kitchen cabinets. I had taken out all of the visible screws, but the cabinet wouldn't budge. I pulled on it, pushed on it, and banged on it, but it was stuck. I stepped back to think where the hidden screws might be, and WHAM! the thing fell right off the wall. LOL , that only happens to me when I try for hours or days to take something apart and then get another person to try. I had a friend in SA Tx. that would come over and I could ask her where my keys, glasses, or an object that isn't used much were hiding from me and she would know ! I've about bought it from everything under the sun. One time while on a road trip across the country at 3am the highway shifted between maybe 3-4 missing concrete berms. Someone must have taken out the signs cause the lane just ended with a pile of gravel. If it wasn't for the guitarist friend watching and pushing on the steering wheel it would have been over. Still, almost caught the blunt end of the concrete barrier at 80 mph. |

Is this another 5mph bumper issue - I'd think a plane like the F-16 could be dropped 5' and not take it in the tires and shocks ?! I thought it was Aircraft Carrier rated ! No, the F-16 is Air Force only. The F-18 IS carrier rated, and has a VERY sophisticated "grasshopper" landing gear system to handle a 40,000 Lb aircraft making such a hard landing repeatedly. Also, in production, the F16 in question may not have had landing gear installed at that stage of assembly. Jon |

Jon I think the story is bogus or the term F-16 is misused. e.g. if a wing only chunk of airplane was being transported - e.g. only the wing - it isn't an F-16 and can't 'land' at any speed by itself. Now if my crane thought head is on, there would be a cable down to a hook, the interface to a spreading Bar and then two points (or a spreading T four points) of attachment to the plane. If a bolt in one of the sub points - holding one end of the plane - and it did a nose drop or a tail drop - then an F-16 could be valid and just a rookie on crane technology and drop terminology. IIRC, the F-16 was rated for large carrier emergency landings. Useful in special op returns when air refuel is not timely or possible or viable.
