My thanks to all the members who provided information for the CH-46 database. It's coming along fine. I've finished the straight A models, now working the first ~40 D models that began life as A models, before I move onto the straight D & F models.
Despite my ~18 years in the military, I've come across some abbreviations I don't know. Here are my guesses for some:
BWR = Bureau of Weapons Representative? (i.e. govt acceptance rep at the Boeing factory)
FR = Fleet Readiness? (again, at Boeing factory)
HAMRON = Hqtrs & Maint Sqn (aka H&MS, correct?)
A&T = Assembly & Test? (a division of NAS flight department?)
O&R = Overhaul and Repair? (a division of NAS flight department?)
COSA = (I have no clue.)
Naval Air Stations/Facilities/Activities usually have some sort of intermediate
maintenance activity/department (AIMD) to perform mid level maintenance
above the level of squadron maintenance and below the level of depot level
overhaul. The data suggests that airframes were flown to North Island A&T for dis-assembly in preparation for surface shipment to Vietnam. Once in Vietnam, they needed to be re-assembled, again, at some sort of intermediate level maintenance activity. So I suggest that A&T refers to 'Assembly & Test' in conjunction with O&R 'Overhaul & Repair.'
COSA is only listed for Hqtrs & Maint Sqns (H&MS-16, 30, 36, & 56) with the exception from 16-Sep-69 to 07-Nov-69, where it is listed for HMM-165.
Can anyone explain the discreapancy?
Semper fi!

Could COSA be Commander Oceanographic Systems Atlantic. They do a lot of surveillance in the Atlantic and their counter part in the Pacific is COSP.
Maybe they had been transfered and used in Atlantic Operations at some time.

Here is another thought on COSA. It might be Combat Operations Southeast Aisa

COSA is Combat Operational Support Activity.

Don't know if this is of any value, but HMM-165 had been "withdrawn" in mid August 69. At the time you show, we were on Okinawa, prior to going aboard SLF.

Vietnam Aviation Abbreviation
My hats off to the lot of you! Thanks for the help with the abbreviations. I'm betting COSA means "Combat Operational Support Activity." hma1369 wins the prize for that one. the others just don't make as much sense, but then again, we're talking naval aviation here! LOL!
Also thanks to Bill Edwards for pointing out that HMM-165 was in Oki during the COSA period. Which leads me to ask if H&MS-16, 30, 36, & 56 were also on Oki during their respective COSA preiods? Does anyone remember re-assembling CH-46s received from stateside? Where and when was this done? Only during the early part of the war? Later on (say, after '69) were airframes flown straight off ship into country? My database shows beaucoup write-offs, in fact almost the entire A series and quite a few Ds as well. But then again, the production line was open and Congress was footing the bill.
Thanks again & semper fi!

A&T = Assembly & Test? (a division of NAS flight department?)

COSA = (I have no clue.)
According to the list of abbreviations in the April 1965 "Allowances and Locations of Naval Aircraft":
BWR = Bureau of Naval Weapons Representative (Tech Rep?)
FR = Fleet Readiness, BUWEPS
O&R = Overhaul and Repair, BUWEPS FR
HAMRON is correct, as is A&T.
I don't know what the distinction is between H&MS-16 and H&MS-16 COSA
As for H&MS aircraft and the COSA, I'm not sure which are permanently assigned and which are temporarily assigned while undergoing repair.
Example from Jan 69 list (The alpha-numeric designations after the aircraft are the aircraft status codes.)
H&MS 16 Da Nang
C-117D 1 A2B
CH-53A 1 BY2
CH-53A 2 C9J
CH-53A 1 G2
UH-34D 6 A10
UH-34D 7 A1B
UH-34D 2 A2
HAMRON 16 COSA Da Nang
UH-34D 1 B10
