I was installing a Donut pannel, The round engine cover on the rear end... Any way It has ram paint on it. About 20 min later on my forarms where they rubbed on the paint developed a nasty rash. My genuis supervisior sais that the pannel is made of fiberglass and the rash was from the fibers. I disagree, Any one know what its really made of or if he is right. I think its something to do with the paint.

Thanks

Something classified? I have no idea how secret RAM materials are anymore, in 1990 it was a Big Deal, now I wonder if it's just common knowledge? Anyway, -I- have no idea.

I know from working on cars and boats you can get a basty rash from fiberglass, but I didn't know the donut was made of 'glass???

I have a fiberglass boat and the rash is the same type except from the boat it lasted a few days instead of only 12hrs...I am pretty shure that the donut is made at least in part of some kind of metal, probey allumium,

RAM Paint? There is RAM and their is paint...not sure we ever imbedded the two together. First off, the RAM is very hard to put on and impossible to remove without blasting. Second of all there is NOTHING toxic about it. What you ran into was plain old fiberglass, pure and simple.

Besides, I don't think we put any RAM in that part of the airframe. I am not familiar with the part you refer to. Can somebody post a picture?

Panel 4309 is the panel number. The panel is made of Aluminum(sp). The pain depending on year will vary. The newer jets with the HAVGLASS paint, has some glass particles in it for a feature I will leave out of the discussion. That area doesn't get touched very well during the pain process, so the particles will be more loose and have a tendency to come off when rubbed like when you stuff your arm up there to rotate the panel lock. I have had the same thing, but I don't remember getting it on the older models.

IDcrewdawg rocks! Thats exactly what I was doing on a newer jet and answers my question perfectly. Thanks

Ah...THAT paint, officially known as Pacer Gem. To clarify, that is NOT RAM.

No pics, however on the block 10's and 15's, the donut was made of the same material as the airframe and painted the same paint as the aircraft. It was installed by using "chocks" to ram it into place than a speed handle to lock it in place. Was a pain in neck to install around the PW-100-200 engine AB section forward of the nozzle.

The real "SOB" is trying to change one of the upper rotary latches that hold the donut on with the engine installed.

Don't let QA catch you putting one on like this.

This "SOB" was doing no such thing, the entire flight line was installing donuts that way after an engine change on the line, how else would you install a donut after an engine change? QA never said or issued any statement regarding this procedure.

Latches? Why would this "SOB" be switching out latches on the line? They're riveted onto the panel. I truly believe airframe would take care of that at Component Maintenance, and next time, don't call me an "SOB", I happen to have certain credentials you don't.

Credientials smedenttials.... blah blah blah. The "rotary" latches are a PITA to change with an engine in, though not impossible. The "spike" on the pannel its self is riveted. Additionally if you have a new panel seal that touches the engine, just put some petrolatum on the seal, it slides right over the engine, no chock needed.

Touchy much AP? He was saying the job of changing an upper rotary latch with the engine installed was a real "SOB", not you.

Oh, and 229 guy, thanks to Roscoe's reference and a little Googling, here is the MSDS for "Pacer Gem": http://msds.ogden.disa.mil/msds/owa/web_msds.display?imsdsnr=181793.

Sounds like some fun stuff (although I imagine a lot of this is for when its wet):

IF VOMITING OCCURS, KEEP HEAD BELOW HIPS TO PREVENT BREATHING VOMITUS INTO LUNGS.

229 guy, more than likely, the rash you got wasn't from the donut at all. I know that trying to get to the upper rotary latches, my forearms would rub on the the engine shroud aft of the donut. It IS made of fiberglas and your arms will get a rash and itch whenever you rub against it.
