Douglas DC4 bathtub fitting corrosion
(OP)
Anyone got info on the allowed depth of corrosion removal in the actual bathtub basin [Douglas DC 4] where the nuts/bolts sit[this holds the wing tip with the main fuel tank] Cheers

1. The DC-4 airframe maintenance manual will be Your best bet. There are companies selling old AMMs.
2. Try contacting Boeing commercial tech support... and ask if they provide any Douglas-heritage engineering expertise for early [prop] DC-3-to-DC-7 acft. IF Boeing/DAC has no expertise on this antique, then they may know who to contact; IE: other mod/repair companies or organizations with engineering support.
3. Check for any FAA ACs, ADs, SBs or SLs on this particular issue.
NOTE.
FAA AC 20-52 "Maintenance Inspection Notes for Douglas DC 6/7 Series Aircraft" comes close... as an example [There may be similar data for the DC-4].
4. The following associations may also be able to help.
"The Douglas DC-4 Association of South Africa" http://www.dc-4.co.za/
"Dutch Dakota Association" [now DDA Classic airlines]http://www.ruudleeuw.com/dda.htm

Doesn't EVERYONE get their tech data from ebay?
RE: Douglas DC4 bathtub fitting corrosion
Hope it relates to airframe repair: might just relate to inspection and general C-54 aircraft maintenance... but at least its a step in the right direction.
I would assume that the associations [noted] would have just about every maintenance and repair document they could get-hold-of on the DC-4/C-54 acft.

However, the data referring to bathtub fittings is on Pg C4-7, which online document does not include, stopping at pg B12-58.
Apparently the info is in volume 2?
Might give you a clue on how to proceed.
Good Luck

Thanks!
An interesting feature before they dive into the technical stuff is Chapter A, general design procedures - go to A.4 for example. How many times have we tried to explain that to a new guy? ...or a not-so-new guy? Or ourselves skipped such steps when, on hindsight, they could have helped avoid a problem.
