Posted: Mon Nov 12, 2007 8:47 am Post subject: Removal of fuel tank access panel

Has anyone on one of their RVs had to remove a fuel tank access panel(the 

ones Van's sells, The twelve screw hole, thick plate). I placed mine on with 

a proseal and I am considering removal. but I think due to the tight fit and 

the proseal acting as a very strong adhesive, and due to the limited access, 

it might be a lot of trouble getting the plate off.



Someone suggested using a heat gun to loosen the proseal but, that did not 

appear to do anything on a test piece of proseal and it would affect the 

proseal that is beneath the structural reinforcing plate around the opening.



Ideas?



Thanks,



John G. 409

John,

  I've taken the plate of off the -7A that was prosealed on (actually have done this a couple times).  Ended up not being a big deal.  Just take the screws out (I used some allen head screws which made taking them out much easier on the 7) and use a putty knife or something similar to get started.  Once it starts just work around the edge prying a little and the proseal will turn loose.

Thanks for the heads up.



I bought some exacto blades shaped likes a chisel head, but still leaves the 

access between the skin flanges and the tank attachment angles a slight 

issue with the blade handle.



Hopefully it will be easier than my mind is imagining it.

Use a PLASTIC putty knife...  works well, doesn't carve out aluminum!



Also, it will avoid the wrath of J.C.

Just a reminder... anyone removing proseal should use extreme caution to

avoid scratching the underlying aluminum.  Use plastic tools.



I am always somewhat paranoid of scratches as I had an elevator spar on my

Cessna 152 crack do to a scratch.  Good thing my A&P noticed a small bit of

flex in the elevator hinge points on an annual and wouldn't let it slide.  I

can imagine elevator spar failure in flight will ruin your day and probably

those below you as well.

You might also consider using the non-hardening version of PRC for 

resealing the access panel. That is what Mooney specifies for their 

access panels.

Use of a metal putty knife is a "Termination Offence" at work (Spelling

is Canadian cause the planes are designed by French Canadians.  The

damage inflicted on aluminum skin quickly exceeds the 10 to 15% damage

depth permitted to be blended smooth after scrapping.  Plastic scrappers

are given out by the dozens.



We remove easily 100 panels per night using fiberglass reinforced

plastic scrapers. Teams of guys "Lay to" the process to get at the

goodies needing fixing below the covers.



Skin knives are contraband yet some have them hidden to use leverage

after the perimeter seal is broken with plastic scrapers.  Boeing

surplus and Ebay have been a source of all things connected with

sealant.

"The Tree of Life is Self Pruning". (No disrespect intended). 



If a builder is not aware of why aluminum edges and drilled rivet holes

need deburring, then why the use of a metal scraper can condemn the skin

to replacement is a waste of words.  Of the 800 RV-10 builders, at least

100 must be using primitive tools from their woodworking days.  Leave it

to an RV-7A builder to turn on the light to this age old problem.  Why

not just use a screwdriver and hammer and get it over with.  And James,

I did not shout.



Be diligent, Build Safe, Fly Often, Fly Safe, Live long.



Off to work with my plastic scrapers in hand.



John C.

John,

  Thanks for reminding me why not to post to these boards.  I do certainly appreciate your wisdom in correcting the errors of my ways as I don't desire to steer anyone wrong.
