I don't think that obtaining plan coverage information requires membership. At least the url doesn't appear to be in the member only section.

If not, here's the appeals language
==============================
3. Representation in Appeals. For the following appeals from FAA enforcement actions described in A2 above, the Plan will pay 80%
of attorney fees incurred (you are obligated to pay the remaining 20%), at a rate of up to $152/hour, up to the hourly limits stated.
a. Appeal to the National Transportation Safety Board (NTSB) at the Administrative Law Judge (ALJ) level--Limit: 25 hours.
b. Appeal of an ALJ decision to the full NTSB--Limit: 15 hours.
c. A petition by the FAA for the judicial review of an NTSB Order--Limit: 50 hours.
==============================
btw, the $152 recently went up to $167.
