Re: FAA forwarded the appeal to PIO to reply
FAA has only called the para-wise comments from the PIO and directed him to endorse copy of the comment to you also. FAA has not decided your First Appeal. You need to appear for hearing only when the FAA call you for such hearing. FAA has 30 days time in normal course or 45 days' time for reasons to be recorded in writing, for deciding the first appeal. After 30 days, send a reminder to FAA stating that the PIO has not endorsed the copy of parawise remarks to you with a request to decide the appeal within time limit.
