I recently talked to my AI about submitting a 337 to install 8.50 tires on my Cessna 140. I provided a copy of a previously approved 337 (found in the 120/140 association archives) under the impression it would make my application "almost" automatic. My AI replied that a few years ago the FAA told FSDO's anyone approving a 337 would be personally responsible/liable for the approval and, as a result, (at least the Scottsdale, AZ) the FSDO was not approving any 337 applications. Has anyone else heard this? Are 337's being processed by other FSDOs? If other FSDOs are approving 337s, am I allowed to submit an application to a FSDO in another state?

Thanks,
Dave
