    Input from others in the aerospace industry on these 2 compounds

    While writing repair dispositions for composite aircraft for the most part I call out EA 9394 to fill in holes of various sizes that needed to be drilled out because of delamination's or whatever. This is considered a structural adhesive and does it's job well. I have been talking to a friend...

    I'm looking at some print outs from

    I'm looking at some print outs from CHERRYLOCK and CHERRYMAX but they don't have the information I'm looking for so I thought an Aerospace person smarter than myself (as there are countless)may be of some assistance. Does anyone know the difference between CR2162A-4-02 and CR2162-4-02? I can't...

    Good Morning, Our procurement te

    Good Morning, Our procurement team is having trouble finding a bolt and has asked engineering for some help. The primary drawing callout is NAS428-5-32 with the alternate being NAS1801-5-64. I can't seem to find the alternate anywhere so I'm not sure if it is even a good number. Is there...

    Good Morning, I'm hoping to get some input from other engineers that have done Liaison engineering work in aerospace. I just completed my disposition on a discrepant item that changed a couple of nut-plates on a nut-strip because of mis-drilled holes. The last instruction in the disposition...

    I have a vendor telling me that QQ-P-35C, TYP 2 VII has been superseded by AMS-2700. I can't find anything on this so I'm hoping someone here has much greater research powers and can point me in the right direction. Thank you all.

    I know this is a little off topic but I'm hoping someone on this site can point me in the right direction. We are a small aerospace company with government contracts to install our products on military aircraft. We may be doing the same for some other aircraft and I was wondering what the...

    Priming Buck tails

    Good Morning, I'm currently in a discussion with other engineers and QA as to the requirement to prime a buck tail after a solid rivet has been driven. The rivets we use already come chemically treated and the area in question is not painted so I see no reason to prime the driven rivets. Does...

    Low adhesion sealent

    We currently have an issue with filling the gap between our window and frames using low adhesion sealant PR-1428, Class A. The sealant is runny and hard to keep in place for forming. The assembly must be pressure tested so complete sealing is required. I'm thinking about using another low...

    AISI 304 1/4 Hard vs AISI 301 1/4 Hard

    Good Morning all, We have a part that the drawing calls out for 0.050 sheet AISI 304 1/4 Hard but the vendor says all they can get is AISI 301 1/4 Hard. The part is a small (2 1/2") triangular flat pivot bracket. The bracket is 0.050 thick and does not see much stress. It is my opinion that...

    Form, Fit & Function

    Good Morning All, I have been having an in depth discussion with the owner of my company as to when a dash number needs to be rolled. It is my contention that any time the fit, form or function of a part is changed than the dash number must be rolled. He has countered that what happens in the...

    QQ-P-35, type 11 vs QQ-P-35C, type 11

    Does anyone know the difference between passivate per QQ-P-35, type 11 verses passivate per QQ-P-35C, type 11? Some of the parts came in looking kind of a gray-black and others the standard silver. I have done some research and found that the specs have been updated and cancelled and updated...

    Passivated Per QQ-P-35C,type 11

    Does anyone know the difference between Passivate Per QQ-P-35C,type 11 and Passivate Per QQ-P-35,type 11. I don't have access to the specs but I'm sure the differences must be small. Thank you.

    Material strength

    I have a small "L" bracket made from 2024-T3 QQ-A-250/5 at .13 thick each leg. The drawing calls out 2024-T351 QQ-A-200/3 in the latest revision. Is there much difference between the strengths of the 2 materials? All the other dim's are the same. What do you think?

    NAS1801-3-8 vs NAS18-1-3-08

    Good Morning, I'm researching what I thought would lead to a quick answer but have come across something confusing. It looks like NAS1801-3-8 and NAS1801-3-08 may be the same part but they have different NSN's. The -8 is 5305-01-089-1520 and the -08 NSN is 5305-01-579-0208. If they are the...

    Good morning all, I'm trying to find the spec for NAS7404 and keep striking out. I have even went to the company owner to purchase it and he tells me he can't find it. This is a 100deg countersunk screw and I need to add the O/D of the csk after drilling. Can someone please point me in the...

    Is ASTM A213 the same as AISI316

    Good morning, I'm trying to find out if ASTM A213 is the same as AISI316. I have the spec for ASTM A213 so I'm hoping someone on the site can point me at the spec of AISI316. As always guys thank you for all the help.

    MS35338 Split Lock Washers

    We call out MS35338-40 split lock washers on the drawings which are steel, cad plated. For some reason the buyers want to see if MS35338-40M split lock washers are a suitable sub for them. I'm guessing the difference is in the plating but I can't find the spec for the MS35338-40M. Is there a...

    Nutplate subs

    We are currently using MS21061L3 and MS21059L3 nutplates on our assemblies for ease of installation but my boss would like us to use nutplates with a changeable floating retaining nut. He suggested using NAS1791, NAS1792 or NAS1793. I have been searching for the better part of 2 days and can't...
