I change two of my 10 years ago the other two could go bad. It helps to keep them full of fuel they last longer. It is a job . My plane was a Comanche 260. Great video explained everything good.
I am very curious, how long the seals in my '86 Malibu will last. No rubber tanks but I wonder if the material that is sealing up the aluminum is any better than there bladders. Sometimes I wonder if the biggest problem will be leakage or little pieces of sealant clogging up the fuel filter, which as we all know sucks.
They're about 1,000 bucks per bladder. Labor is about 10 hours so anywhere between 800 and 1k in labor per. Comanches with the aux bladders have a total of 4. So you're looking at 1,800-2000 dollars installed, per bladder. Life cycle of a bladder should be in excess of 20 years but in practice with weathering, top of the bladders remaining dry for a long time due to flying with partial or even empty auxes all the time, you'd be looking at 10 years before these things start giving you trouble again. I prefer Piper's integral tanks; unfortunately Piper didn't really have a replacement to the comanche (I don't consider the Piper Lance a bona fide in-class replacement in the least, as Piper argued), so you're kinda stuck with these old Comanche contraptions if you want something between an Archer/Arrow/Dakota and a 6-place airplane like PA32 and A36 C210 et al. Their competition being the Beech 33/35 bonanzas of course, which also carry the expense and hassle of these bladders, to be fair to the comanche.
FUEL bladders although a pain sometimes... MUCH safer than metal or Wet wing tanks in survivable accidents ! they absorb impact better and may not rupture vs the other style... I'll take my bladders any day.. IMO
