    Anyone know where i can order this Boeing Bolt BACB30NWK14Y-5H-TCP-SO-8914

    BACB30NWK14Y is missing a number for nominal thread size that should show up between the W and the K. The final Y is .0312 oversize, and everything after the Y does not exist per the Boeing spec.

    Fuselage Inserts

    To expand a bit on the clear definition provided by rb1957, here is a bit of real world example. Boeing uses a special numbering system to identify the fuselage inserts. They do this (I guess, I am not Boeing) so that the major aircraft components such as landing gear, engines, wings...

    Drawing note with quotes

    My background is not structural so take my point with a grain of salt. You have probably already reviewed this, but MMPDS-15 Chapter 2 for Steel gives some information about H900, though it does not detail the exact process. It also supports Wil's CAUTION comment about fracture toughness.

    Boeing again pt2.

    3DDave, your point is well taken. To insure a clean sheet would have to be a regulatory process, at a point in the design program that makes sense for safety. Otherwise the financial departments of the airlines would certainly follow the logic trail you stated. Star for you.

    Boeing again pt2.

    Quote from 3DDave (who I agree with) "So Spirit is another company the FAA let run riot? Another 350, or so, will be killed in the US general aviation operations this year. Maybe the FAA needs to get out of their cubicals from time to time and actually do some work." I think the FAA is too...

    Net Zero Disaster

    We need to cover the solar panels with Chief Engineer Montgomery Scott's Transparent Aluminum! It allowed carrying tons of whales and water (from the movie Star Trek IV - The Voyage Home) and still had a clear view of the whales inside so I would assume no blockage of the energy in the sun's...

    JohnRBaker THANKS for the great photo survey, visiting sites I will probably never get to see in person. Much appreciated!

    If improperly done....What are we including with this statement on the major-minor determination?

    This may be a gross over-simplification, and I am open to correction by my peers. Admittedly my experience is in Part 25 Transport aircraft certification, so I am weaker in other Parts of the regulations. As I understand the issues about alterations and repairs, both major and minor, here is...

    If improperly done....What are we including with this statement on the major-minor determination?

    RoarkS is spot on for 14 CFR Part 43, Maintenance. However, for those of us in the Transport Category type design/alteration world, 14 CFR Section 21.93 says this: "...A 'minor change' is one that has no appreciable effect on the weight, balance, structural strength, reliability, operational...

    Learning How to Type

    drawoh, I have zero Unix experience with which to compare. I really like the "...charitably described as user-hostile..." phrase. I remember thinking similar thoughts when I first learned Edlin, the very early MS-DOS editor...though I never put those thoughts into words as eloquently as you did!

    Learning How to Type

    In the 1970's when I attended junior high, my dad insisted I take a typing class. Turns out that the typing class I took for typewriters (my dad envisioned me typing papers for college classes) has served me extremely well throughout my career with computers...thanks Dad! I thought a bit of...

    Thanks all, I appreciate the feedback.

    Alaska Airlines flight forced to make an emergency landing...

    I have been trying to keep up with the sequence of events. I would appreciate correction if I missed something. As I understand it, the four missing bolts are there only to keep the door plug from moving upwards. It is the 12 pads surrounding the door plug that transfer load from the door...

    CONGRATS JRB! We hit 50 this year so we are chasing you as fast as we can. [thumbsup2]

    Alaska Airlines flight forced to make an emergency landing...

    Just now received the FAA SAFO about the door plug. I quote the recommended action here from the SAFO. "Recommended Action: Operators are encouraged to conduct a visual inspection to ensure the door plug is restrained from any movements through the two (2) upper guide track bolts and two (2)...

    Boeing again

    The comment from 3DDave about American labor piqued my interest. I do not work at Boeing and have never worked at Boeing. I do have a question for someone who is in a position to know, such as a current or recent Boeing employee. As part of my job I have been to a number of United States MRO...

    Update on 35% scale B-29 homebuilt

    Wil, good catch...I completely missed the pilot compartment. I had been reading several articles outside of Eng-Tips about RC and still had it stuck in my brain, I guess.

    Update on 35% scale B-29 homebuilt

    It might take some experimenting to get it right, but I suspect if the RC plane was thousands of feet below the real plane, there should be a few moments of harmony where the perspective makes them both look about the same size, and if caught at the right time, the speed difference won't be...

    Fake parts scandal hitting major airlines...

    Many years ago (about 30) I was tasked to be part of a team from my company sent to a federal special agent who was investigating some bad parts. These parts were antennas and the special agent had determined that a certain facility was obtaining antennas from airplanes, cleaning and...
