Where is a good place to purchase this?
I see some list it as 0452200-1-279 (updated?)
I'm replacing the cowling also.
I Googled that part number. There appear to be lots of these available new, cost around $550-$600. (for example:
www.cessnaparts.com [
cessnaparts.com]). Most call it "Fairing." One site calls it "Scoop."
Are you sure that's the right part number for a C-150G? Do you have access to the correct parts manual? Check here:
