MIL-A-008865 vs MIL-A-8865B
(OP)
Does anyone knows if MIL-A-8865B is the superseding document for MIL-A-008865? There are no history for MIL-A-008865 except that it is cancelled with no replacement. Anyone out there have a copy of MIL-A-008865?
Thank you

MIL-A-8865 MIL-A-008865
FWD 8G 20G
AFT 8G 10G
Lateral 1.5G 10G
Up 2G 10G
Down 4.5G 20G
I am not convinced that MIL-A-8865B supersedes MIL-A-008865 because the face sheet of MIL-A-8865 does not indicate that it does supersedes the requirements in MIL-A-008865.
Any ideas where to get a copy of MIL-A-008865 which has been cancelled? Or is it relevant anymore?
RE: MIL-A-008865 vs MIL-A-8865B
the inertia factors you've quoted for 008865 are in 8865B under seats (table 1) rather than litters (para 3.2.2).
maybe the original installation used these higher factors to be conservative ?
RE: MIL-A-008865 vs MIL-A-8865B
Original issue of MIl-A-008865A cover page upper corner reads:
USED IN LIEU OF MIL-A-8865 (ASG).
Cancellation page of MIL-A-008865A reads;
FOR FUTURE PROCUREMENT, SEE MIL-A-87221.
Continuing on, MIL-A-87221 has been cancelled and reads;
FUTURE AQUISITIONS SHOULD REFER TO AFGS-87221A.

Thanks for the valuable feedback. Do you have any idea how I can get a PDF copy of the AFGS-87221A document?
Thank you.

i've searched this for "litter" loads, as this is what i think you're interested in. the result is on pg289 with inertia factors as per 8865B (as you've quoted above).
