| Subject: | Re: Cooling exit ramp |
Of the 8 cowlings out in the world, there has only been one owner who is having
buyers remorse. Personally, I think his plan is to make and sell his own
cowling.
There are no issues with the cowling. As approved, the cowling works fine.

Subject: Re: TeamGrumman-List: Cooling exit ramp
I'm not seeing the issue here. Is someone having a problem or is there a
personality conflict?
Have looked both sets of pictures and due to poor quality photos cannot clearly
determine where the issue is?
Did the stc holder call the faa to report the end user? If so, why? I am
unable to follow what is happening here.
Am interested in the cowl and would like to understand the issues.
