That's because they are only supposed to be tightened up finger tight!:eek:

" i can assure you tommytug is nothing to do with me "

:hmm: The understanding of genetics is a complex and ever developing field....to the outside observer therefore, it can be confusing regarding the seemingly close intellectual capacity displayed by those of a simililar, if not incestuous, genetic flaw........

Find a torque wrench which will accurately tighten to the usual 6 lb in. A tiny torque.

Clearly thats we find so many on our pre flight safety checks tramwell, engineers are not tightening them correctly:ugh:

Doubt it. Probably a case of removing the one on the wheel to be replaced, putting it on the ground, then fitting a new wheel which has a new one fitted anyway. A failure to pick up FOD is more likely.

People should be aware of the dangers of FOD, next time i see a wheel being changed i wil be reminding them of the dangers, imagine a cap going into the spinning wheel on the front of the engine with the engine running! :eek:

"The spinning wheel" I think you mean the fan or 1st stage LP compressor if being pedantic. I don't think many engineers would appreciate you reminding them on how to "torque" a valve cap properly. Has "The Hitcher" moved from Norfolk to Chesire.:ugh:

This thread is very AirMech..

Cue Dunny

I'll get my coat!:E

This might help at least you dont have to remove the dust cap to check the pressure even the security guards could have one to save the Engineer some time.

YouTube - Aircraft Tire Pressure Monitoring System (TPMS) from Crane Aerospace & Electronics

i am really surprised by the huge amount of professionnals on here who are able to f.ck a fly ...

So many villages missing their idiots and only 1 PPRuNe. Tommy ( Walter Mitty ) Tugger - go home. Next time you leave the village, leave a trail of dustcaps to follow.:rolleyes:

How many times we have all found a tyre (with a tight valve cap) at 50psi 2 hrs after hitting the stand and dustcaps are what we are obsessed with to record posts! I tight turn offers a greater threat!

Most of us have procedures to check pressure on a schedule and have spare valve caps.

TROLLS PROCEDE!

I can't believe this thread has attracted 197 hits of erm.. "Engineers" arguing over the function of a valve cap..

It's not the question but the answers that are painful :ugh:

Might be time to throw in the towel fellas and finding a more suitable occupation. "Would you like fries with that?"


Shouldn't this be in the spotters forum??

:sad:

Time to move onto a more stimulating thread!

199 :hmm: ..............

Jesus, is this still going?

I think we need the bloke who drives the honey cart to give his opinion on the matter,and maybe see what the guy who paints lines on the taxiways thinks about it.....

FWIW, you can get torque screwdrivers that will give you the correct torque. Place I used to work in used them for tightening the valve cores (which strictly speaking are also supposed to be torque tightened). A bit picky though, and means every torque screwdriver has to be on the company's calibration register, etc etc.

Can a moderator close this blasted thread?? It's done to death!:E

Mmmm - no don't close the thread, is interesting and yet amusing to consider the importance of the valve cap.
I would have thought that the impact pressure on large aircraft tyres is quite high and that the sealed cap assists keeping the tyre valve seated.

Cheers

Well, we need someone to secure the caps to the taxiway in case someone does find a loose cap & starts a long winded & pointless thread on here.

this valve cap, is it on a conveyer belt?

Where is fu&@#ng Hitcher
 

I had to run to stores today,because on my walk around I found my PRIMARY SEAL missing. Then I couldn't find the torque wrench............. Almost changed the wheel, then remembered its only a dust cap. Hitcher wherever you are bring back my cap. It wont fit on your Ford's tyre. A319 cap......sorry.

This thread needs some sealing, by being closed!:p

No, it doesn't need sealing...it needs to be torqued about in a professional manner.......:E

It's been massively over torqued already.:E

If the thread is closed, is the primary purpose to keep the conversation in, or the nonsense out?

PERRIN
 

No. keep this going, by the way went into my hut at home I have 54 yellow valve caps to any line engineer so he can depart A/C on time!!!!!!!!!
Keep them up boys.
:ok:

This thread is like the parrot sketch.. "It is Deceased!!":E

sounds to me like its got to you mr ratman, best you stay away.

To avoid losing the little blighters, I have been accustomed to holding valve caps fastened to my tongue while using the valve; this is quite easy and done by creating a little suction. The method can be used for up to 4 caps simultaneously, perhaps more with a long and sinuous tongue.

Having read this thread thoroughly I am now concerned about several issues which are beyond my technical competence, and perhaps the wealth of professionals here could offer advice.

Firstly, if someone, perhaps a pilot, asks me a technically important question when I'm encumbered with the caps, the reply may not be very clear, and can sound like "uh oth". Now that we are introducing SMS, should this be considered a risk?

Secondly, is there a possibility of an adverse interaction between saliva, itself perhaps contaminated with a number of chemicals, and the gas in the wheel? If so, is that a risk, too?

1. Perhaps.
2. Possibly.

i have scrolled thru the whole thread, and I can't see anyone asking - what is the release number/batch number for the cap? If it doesn't have one (ie - traceability), can the cap that the engineer finds in his pocket/toolbox/off his car be put onto an aircraft?

are you going to ground an airliner for want of a valve cap without a release note?

this question asked by someone who has a nice array of valve caps in his pocket/toolbox/car/bikes :E

TLTF if you ask the powers that be, the textbook answer would be if it's not deferrable and you haven't got a correctly certified part then it stays put until you have. But as an engineer you know that don't you ;)

And yes I do know what happens in "the real world"

Oops sorry did I just bounce this thread? My bad :D
