Though generally speaking when you land at a towered airport they usually
close your IFR flight plan for you,,, but it is more a courtesy rather than
something they are 'responsible' for,,, so-to-speak. In the end it is the
responsibility of the PIC


I don't believe the statement above relative to an IFR flight plan to a
towered airport is correct. In that case the procedure is that ATC
closes the flight plan for the pilot. This is the standard procedure,
not a "courtesy" to the pilot.
