Dumb Question?

[nitram38]

If you had an A4 service on a 747-300 and it had an existing Thrust reverser locked off due to failure, in what order would you complete the repairs if you knew that 2 different engines had to be removed for pylon repairs? (found during A4 and the reverser was over 10 day Cat C plus 10 day extension DMI)
Would you test the faulty reverser engine first (so that you can at least diagnose the problem and fix it while the aircraft is disabled) or would you steam in and get the engines removed, do the plylon repairs and test the reverser once the engines are re-instated?
Please help settle this argument.:mad:

You will get hundreds of different opinions on this but here is my tuppence worth.

Test TR in order to diagnose fault & establish faulty componant(s). Order spares. remove engines & carry out pylon work. Install engines. fit serviceable TR componant(s) and function.

In an ideal world you would have time to diagnose and function prior to engine removal. But in this industry downtime is lost revenue, the above sequence would probably give the least downtime as you're not leaving an engine on wing waiting for and then fitting TR spares when you could be progressing the pylon work.

No need for a t/r to be locked out for more than 10 day cat c before someone with a bit of nouse should be able to rectify the defect.


What engines are you operating?

There is when the operator flogs the a/c to death with no down time.:uhoh:

[Redstone]

yea well, i would suggest that any mech worth his salt and experience on type should know where to start, and how to finnish.

Redstone

worth his salt?
That is an aweful lot of salt when looking at some of the wide bodied engineers.
Is there some sort of weight for age handicap that can be applie here? :ok:

[Redstone]

An interesting conundrum you pose there Bolty, but as with all enigmas the truth lies within.

Your observations on the girth of the average engineer are, as allways, on the money. As with the increasing size of airliners, so it follows the size of those who repair and certfy said airliners seem to be proportionally exponential. However, there must be some system of sorting the wheat from the chaff, as they say. Yes I quite agree that just because ones mass times accel is pulling them toward the center of the earth with greater effect than the guy working up on the APU does not necesarily equate to a greater net worth.

That having been said, I do however believe that there are still a few amongst us who obviously belong in the observer corps, and seem to have turned inaction into a career, and quite a succesfull one at that. Not to mention those amongst us who have turned mediocraty into a lifes work. The reference I made was perhaps on the face of it a little misguided, and I have to admit left me sitting on the fence.

Yes Bolty, I would have to agree with you that there must be some for of "handicap" with regards the weight for age, or aptitude for ability, however I will just say that this is one area that should be left to self regulation. Call a spade a spade as it were. If you work with a dumb $hit, call them a dumb $hit, and fix that f#$king t/r you slack pr!*k

Touche Turin, that cuts to the bone......................

Getting back to Redstone's question as to what engine type we're dealing with here, if it is an RR installation then there may ample time to trouble-shoot/ replace any defective components in the stand prior to reinsatallion if the defect was isolated to the engine/ T/Rev insatallation being removed/re-insatalled:ok:

i.e air motor, drive cables, lock g/box etc.

[Redstone]

Indeed Bumpfoh, you are quite correct. The RR T/R system allows for many of the "usual suspects" to be checked off wing. Sense/muscle lines can be leak checked also, some of which are easier to replace with the engine off anyway.
