Time and details
To remove the old wing tips and comply with the ad was 48hrs,
366 hours for install of new tanks shop rate is 80/hr
There are no loading or air speed restrictions to stock, which has really impoved my decents as we live right next to the mountians so arriving from the west with a MEA of 16k within 30 miles of the destination airport makes for steep decents.
I should note that I was very cautions about flying within the posted limites on the old wing tanks (obvously so was the second owner) and when the wings were pealed back for the AD inspection there was no sign of damage at all anywhere.
The tanks are composite, I assume glass and maybe a little carbon fiber. Each tank sits in the void section of the wing, these are the same spaces that the stock ling range tanks occupy so I think that is why there was no flight or loading restrictions.
The tanks are configured with an inner and outer independent tank on each wing. They use transfer pumps to move fuel to the main tanks.
Hope this answers the questions. I will try to attach a few pictures for clarity.
