Inflatable door seal electric pump

[Galvine]

I have installed the Bobs Field inflatable door seal. Hand pump only.

I have the electric pump but apparently I need a Field Approval to have it installed as the STC is no longer available for the Skymaster.

I have the installation instructions and ICA paragraph from Talco Aero that can be submitted to the FAA.

If someone has a P337 with the electric pump installed and has some drawings of the installation, that might help if getting a Field Approval I have been told.

Any other advice to get this accomplished would be appreciated

Thanks

Greg
