    Aviation parts are tracked from cradle to grave with endless paperwork. It starts from when the alloy is made well before it’s end stated is a bolt. That is how safety is ensured. For example the Sioux City United airlines crash was tracked to a fan disc that failed over time. The cause was a stress crack tracked back to the manufacturing of the disc and the fact too much of one gas in its smelting created a less dense spot that began to stress crack.

      Wow! Something so little (too mush gas) can cause such a massive problem’ that’s crazy!!!!

    I remember having to pull a turbine back out because the guy fitting the ignitors somehow managed to drop the last bolt into the combustion can.

      @Sean Carroll no but we ahd just spent a good portion of thr day doing the job because I was teaching new guys and this ham fisted twit dropped a bolt. That was just one of many stupid things he did.

      Bought a boreascope because I dropped a 1/4 stainless steel bolt in the compressor section of a turbine one night on a 407 . Got lucky finally and got it by chance with a set of magic fingers.

    If they were to raise the price of the bolt to $200,000 this might not seem so absurd. :-)

    • Shadovanish

      Charging $200,000.00 for this single bolt seems absurd, even for a military specification part price.
      I'm thinking for this bolt, maybe a $1000.00-$2000.00 price range seems more believable to me.
      I can believe that some bolts could cost around $200,000.00, but those would probably be large explosive bolts, used for space rocket stage securing/separation & launch pad to rocket securing/separation.

    the fact that a bolt is $10 is impressive in itself

      @Aaron LC honestly isnt wrong. If its a bolt that is in a hot section or attaches to a critical rotating part 500+ each is common. Some orings can cost as much as 2k easy. Aviation is not cheap.

      I'm confident the bolt costs in excess of $100.00; likely closer to $1000.00-$2000.00 or higher.

    i just came here to say in no way is the bolt $10, i absolutely gurantee that its easily over $100. a simple bolt in my ford engine is $150 theres no way they are going to use a $10 on a fighter worth hundreds of millions of dollars.

    $10 bolt cost the taxpayers about $700. A $30 ratchet is about $400. We won't find out where this money goes but we do know where it isn't going. Corruption.

      It's a fact as soon as anything has an "aerospace" application the price goes up. Some bolts can be bought at the local hardware store at a fraction of the price that are infact the exact same bolt.

    • Brian Lamb
      Brian Lamb Hace 2 meses +1

      @Dave Dixon Most of the bolt's/nut's/general hardware you are talking about are in the hot-section....IE high pressure turbine, combustion chamber and afterburner area (internal ) A prime example would be the nut, retaining ring and lock ring that holds the HPT (high pressure turbine) in this nut alone can run around 4000 dollars and that was when i retired 20 years ago. But when you consider the heat and stress its under that price is cheap compared to destroying a multi million dollar engine and the possible loss of the aircraft.

    • Dave Dixon
      Dave Dixon Hace 2 meses +1

      @Brian Lamb Agree totally, they are generally manufactured in thousands so the cost comes down and designers use them whenever they can, however there are certain bolts/ nuts which because of their specialised requirements of material or design may cost hundreds or in a few cases thousands of dollars each. Most aircraft quality bolts have threads cold rolled into them rather than a thread cut into them this makes the thread much stronger which is why you don't go to the hardware store for bolts for an aeroplane.

    Safety wire by hand?

    • Dave Dixon
      Dave Dixon Hace 2 meses +1

      If you cant do safety wire by hand you are no good as an aircraft maintainer, having 48 years experience I preferred to do the majority of the wire by hand, using specialised wire locking pliers to finish it off , if you use the pliers incorrectly it could work harden the wire or over tighten it reducing its load capacity. In many locations you have difficulty getting tools in or you can see what your doing or do what your doing but not both at the same time, as an example there was one occasion that I was literally resting on my head with my total bodyweight whilst using both hands to replace a bearing and retaining bolt and locking the bolt in place, it took about an hour, if you work on aeroplanes you need to be flexible.
      On operations you need to do the job faster the book might say "1. remove engine" but that takes hours of work so you remove enough things for access and then rebuild, so its a couple of hours instead of days of work
