i need to do about 15 NVQs in the next 4 weeks and i got loads of sheets but cant answer all the questions. obviously some of the stuff is relevant to particular aircraft as i work on 747, but the company also service 777. Heres a list of main questions im stuck on. any help is appreciated!
What is the health and safety notice that was recently circulated RE: engine transportation about? (i dont know how recent that is!)
What is important to ensure before the aircraft is docked in maintenance bay
what is significant about the red handrails (i think it means they can be dropped to increase clearance)
who can aperate moveable docking (i assume this is people who have had relevant training and/or certfied)
what significant activity is carried out on the aircraft undercarriege to dock the aircaft (chocks??)
The 777 spiner assembly uses different length/weight bolts to 747, why?
Why does the elevator PCP have different hydraulic supplies to it (backups system? one for return line?)
the outboard ailerons move up further than down, does the elevator do the same? if not, why?
What safety precautions/PPe should be observed and why(pressumably cos it contains hydraulic fluid)
On what principle does the fire bottle switch work?
What are your responsibilities to H&S when working on fire bottles(CBs tagged and pulled?)
How are fire bottles tested for serviceability? (weighed?)
On 747-400, what indications do you get for discharged bottle? (orange or red message on upper EICAS?)
What is CPF (corrosion preventative fluid?) and what is purpose? (prevent corrosion?!?!)
what maintenance manual; chapter covers it application(ATA 100 chapter)
What is the purpose of the CCL/CCR (component control log? keep track of rotary componants?)
what essential informmation goes on CCL? (part number etc?)
what is difference between bonded and quarantine stores?
what labels and where are placed on CCL if you are returning a squib from fire detection?
What is anodisin? what examples of use on 747?
why might we prefer primer to zinc chromate?
List the steps you should take to take a bare aluminium alloy to complete surface finish
Cheers for any help u can provide, my apprenticeship my rely on me gettin these NVQs!!

Who u doin your apprenticeship with mate? I'm with My Travel Aircraft engineering at Man Aiport!
oh no your questions seem mechanically biased!, not my forte! hence i'm an avionics engineer, but i'll help best i can!
WHO CAN OPERATE MOVEABLE DOCKING - As u say relevant training and/or company aproval
WHAT SIGNIFICANT ACTIVITY IS CARRIED OUT ON THE AIRCRAFT UNDERCARRAGE TO DOCK THE AIRCRAFT
As u say chocks but they could also be wanting you to say stuff like ground lock pins too?
OUTBOARD AILERONS MOVE UP FURTHER THAN DOWN, DOES THE ELECATOR DO SAME? IF NOT WHY?
It doesnt i dont think (but depends what aircraft it talking about) i think this is asking you to talk about differential aielorns but i'm not sure, have u any idea if its refering to a specific aircraft?
WHAT SAFETY PRECAUTIONS/PPE SHOULD BE OBSERVED AND WHY?
Whats this referrring to specifically? If its hydraulics then usual precautions when usimg skydrol i assume, goggles, gloves and barrier cream, wash off skin imediately, can be slippy under foot, absorbant fibre (chicken s**t) down if spillage? ETC and can always put see the COSH manual if u want some brownie points too! LOL
ON WHAT PRINICPLE DOES A FIRE BOTTLE SWITCH WORK
Could help ya out and explain but i may not get it 100% your best looking it up in AMM 26-20-00
RESPONSIBILITIES HEALTH AND SAFETY ON FIRE BOTTLES
Yeah CB's pulled and tagged, but i'd say do not operate warnings on fire handles etc, plus if its not essential that u need it i'd disconnect squib so that bottle can not be fired misakenly, and not forgetting to make sure theres no voltage on the plug (with a multimeter) before reconnecting (that bit very important!) especially if been performing squib test!
INDICATIONS FOR DISCHARGED FIRE BOTTLE
Dont work 747 so not sure for that but in general yeah i'd say message on EICAS maybe, and possibly also some sort of indication on the fire handel somewhere, but i'll be honest a while since i done a squib test or anythin so your best refering to AMM for that! 26-20-00 again cause i not 100% my answer correct
CPF QUESTION
Yeah as u say prevents corrosion but i assume it needs a fuler answer not 100% what looking for though!
ATA CHAPTER FOR CPF
I'd assume it'll be somewhere in servicing 12-00-00 but not 100% where! LOL Again i'd need check up at work!
PURPOSE OF CCL/CCR
I think it stands for component change log/record to be honest, but u could be right. But as u said its to keep track of rotables etc, when you change a componet you right in part number, GRN/batch numer of new and old part and location of where its installed
ESSENTIAL INFORMATION
As above part numer, batch number, GRN location etc
DIF BETWEEN BONDED AND QUARANTINE STORES
Bonded is serviceable items (with a form1 etc), where as quarantine is where unidnetified or untested/ non-form 1ed items go until they can be tested or issued a form 1 etc and their history can be traced. There a lot more to it than that but thats the general jist of it!
ANDODISING
Again not sure for 747 cause dont work them but anodising in general is applying a coating of metal to another metal using electricity
Hope this helps these are the only questions i can answer straight off! This is all from memory so if i've made any stupid mistakes then sorry! But fairly sure its all correct but u should realy check AMM etc, as being an engineer yourself u should know this should always be done, i'll have a look at the other q's too and look in AMM etc try find out but if u got access to a hanager environment too ask some LAE's etc and check the manuals yourself thats best way i think!

ive only worked on 747 properly and that should be the relevant aircraft, however i have also worked on a piper aztec (Dont ask, its just a large piece of sh!te in college) and the questions could also relate to that

Not a prob mate good look with it! I'm doing my JAR 66 at the mo!
Oh the 777 bolts (in the spiner) question could be to do with balanceing but i'm not sure!
Also I didnt se the one on diff hydraulic supplies (about PCP) must have missed it b4. Yeah it could be back up but there could be other reasons as well, i'll try and find out cause like I say i'm not a heavy so not really sure!

thats kool mate. its a pain in the ass cos i have no access to the maintenance manuals cos we just had our passes renewed and they wont be ready until i actually start work with BA. I just have to ask teachers in college and they are all stuck up ex-raf nobs! if u ever need any help, dont hesitate to ask cos i can find out stuff from lecturers and employees when(or if) they let me in

yeah. college sux! last time i was workin in the hanger i luved it. being trapped in college for nearly 6 months earnin 78 quid a week bites. its so dull and they give us the shitty piper aztec to work on. workin on 747 rules, seat compression test has got to be my favourite job, especially in business class. i can highly recomend the flat beds/seats on British Airways!

LOL seat compression test wait to they start giving u internal/external ligthing, & IFE (if u avionics) or lubeing & Panneling (if u a heavy) they're favourite apprentice jobs! LOL
But yeah the hangar is 1000's times better then college! More money too! LOL

i like workin on the servicing team that works on our aircraft outside the hanger. APU runs are great, 2 hours of doing nothing on an empty plane with nobody to check up on you. absolutely great. I tell u the worst job i ever had to do is changing the engine mounting bolts on 747, pain in the ass. cut my hands to shreds last time cos there just aint no room to manouvre. Ill be doing avionics in my third year but i have seen guys doing IFE checks. must be so hard working your way through 500 odd seats!

LOL yeah its so much hard work, with the inflight video on! LOL when ever I go video shop its like er i've seen that at work! LOL@ APU runs yeah engine runs are good for that too! I've been stook on one all day once! (no.3 wouldnt start when we were in run bay!) LOL. I enjoy doing mods and function tests more a bit more interesting!
