Nice design, Mr. Piper. Beech Bonanza you take off the access port on
the top of the wing to expose the top of the bladder where sender is
located. Remove 6 or 8 more screws and sender comes out. No need for
tank to be empty, down 5-10 gallons helpful. Sender out in 5 minutes.


Agreed. Making the sending unit inaccessible without removing the tank
is crazy. But it's just another goofy thing in aviation, non-specific
to Piper products. I suspect every owner can tell a maintenance story
about "stupid-design-induced-headaches" on their brand of airplane.

Thankfully, the sending units on our tip tanks are much easier to work
on, should that ever become necessary.

Jay, didn't you know that the mean time between failures is inversely
proportional to the difficulty in removing and replacing the component.
The senders on the inboard tanks are therefore much more likely to
require service. Geez, and I thought you would have figured that out by
now.
