If a lost comm situation arises enroute and the clearance limit is the airport, is there a requirement to hold if you arive early? I couldn't find the FAR that deals with the airport as a clearance limit, only a fix from which the approach can or can't begin. (91.185.c.3) Logically it doesn't seem necessary since ATC didn't anticipate the need to give a clearance short of the airport.
