We are right now in the process of certifying our B737 NG for PRNAV RNP 1 approaches.
Does anybody know if there is the need to have 2 FMS to be certified?
I’m looking for the equipment and certification requirements for PRNAV RNP 1. Can anybody help me with official documents from FAA, ICAO or others?
I'm having a hard time to find list with the specific required equipments.
Thanks.

Check the ICAO Doc 9613 (PBN Manual, Vol 2, Part B, Chap 3 Implementing RNAV 1&2) for guidence on all RNAV/RNP Operations. Also check the FAA AC 90-96. I can PM these docs to you if you wish but they are available on the web.

My airline's 737-700s are PRNAV approved, and have a single FMS.
Yup, we had our 737 300s PRNAV approved too, they're phased out now though. Single FMC and down to 0.5 RNP for approaches was approved and possible. Our NGs all have dual FMC though, so i cannot comment on that, however they are approved down to CAT I approaches (GLS).

What your aircraft can do wrt to RNAV/RNP ops has less to do with what equipment you have and more to do with how the aircraft is certified. This will vary from tail no. to tail no. Two aircraft with exactly the same eqiupment may be certified differently due to manufacture date and requierments of the original operator.
It's a combination of what equipage you have and what it says in the AFM. Airbus for example will charge you $90 000 just for the piece of paper in the AFM that says you can conduct RNP-AR ops down to 0.3nm in an aircraft that doesn't need any equipment upgrades.
True enough. Its allways about how much you pay to get it certified. That said im quite happy that all our NGs since 2006 come fully GLS/CAT IIIb certified right outta the factory (personally i just miss the HUD, but thats probably the gadged-freak within me).

As I understood from documents form the JAA you need a:
AIRWORTHINESS COMPLIANCE STATEMENT
And for this you need to check:
The AFM may contain a statement confirming P-RNAV compliance
or - manufacturer Customer Service letter confirming aircraft type with delivered navigation system is compliant
Because there in no such statement in our documents, I have contacted Boeing asking for it. But they have not answerd yet.
But thaks you all for your help!!!
