Documentation Requirements
 

Can anyone add to this thread or point to another that may give advise on the flight test and paperwork required to fly a pod on experimental? I assume you put in a logbook entry to put the plane back into Phase 1. How much testing is required (Hours/maneuvers/CGs). It almost seems like you should redo a lot of testing and add it to the POH to really characterize the flying quality change. What would the FAA consider sufficient? What would insurance company consider sufficient (in case of an incident)?

Assuming you have the latest version of operating limitations, they call for a minimum of 5 hrs of phase I testing for any modification. I stress the minimum because it's up to the designer of the mod to determine the amount of testing required.

In a case like this, I would recommend a complete range of stall testing at all weights. Also if you have an aerobatic aircraft, I would placard the aircraft for "No Aerobatics with the Pod installed".
You may also want to discuss this with the local FSDO, as they have the authority to require additional testing, as stated in the op lims.

I would have a hard time utilizing a pod. The times I would need it, 2 up, full fuel, full baggage, I am at gross. If I am not, I probably don't need it as I can lower the passenger seat back for more room and baggage.
Does your 9 have enough utility you could accomplish the above and still be under gross enough to utilize a pod?

I see the main benefit of a pod being when the fuel burn moves the cg aft. The front end is pretty light on my 9a.
