Approved Data P-Series
Have any P-series owners had to provide "Approved Data" to put holes in the firewalls to pass wire bundles for the installation of a JPI GEM.
I can see in the service manual Page 16-13 section 16-35 describes doing it, as does chapter 13 of AC 43.13-2A, but has anyone had to provide beam strength calculations or similar to "assure that the strength of the structure is maintained". Are there any recommendations from Cessna in this regard for the 337.
Any input would be appreciated as it was suggested today by my local FAA friends that I would require a DRA to approve putting a half inch hole in each firewall. That would seem over kill to me. If anyone has had this before, or has any "approved data" could they let me know.
