The seats need to be changed on a field approval. Talk to the FSDO before you
start, or for that matter before you even buy the new seats.

Changing the bowtie yokes to Ram's horns can be done with a log book entry
citing the service bulletin cited in the Airworthiness Directive as a means
of terminating compliance. You have to make sure the part number of the
yokes you install matches that in the service bulletin.

Instead of just recovering the seats, I'm considering replacing the
original Cherokee seats with newer models. I'm wondering what the FAA
would say if I wanted to take seats from a newer model Piper (with
height adjustment and nice extras) and put them in my Cherokee. If
the floor rails are the same, it should be a plug'n'play change. Of
course, the weights would have to be calculated to reflect weight
changes. But does anyone know if the FAA would allow this if they
came from another certified plane to my Cherokee???

Come to think of it, I'd love to change the yokes in my Cherokee while
I'm at it. Get some newer models instead of these original bow-tie
yokes. And I guess same question would apply -- would they let me
take from one certified model to another???

Thanks guys.
