One problem is that a majority of the IFR is at those
airports with control towers, so pilots forget about
canceling. Much of the IFR to uncontrolled airports is in
VMC weather and the pilot will cancel when 5 miles from the
airport, the IFR flight plan just being a nice way to handle
controlled airspace, weather and TFRs. When they do have to
go to the E airport in real IMC, they forget that they have
to cancel.
Part 135 is required to be on a flight plan [VFR or IFR with
pax onboard or have their own flight following] so charter
flights can't cancel before landing even in good VMC.

|
| Something like:
| Me: ATC, Nxxx is trying to call you to cancel IFR.
| ATC: Verify you're relaying for Nxxx trying to cancel
IFR.
| Me: yes
| ATC: Please call Nxxx and ask them to verify cancelling
IFR.
| Me. Nxxx, please verify for ATC that you wish to cancel
IFR.
| Nxxx: Affirmative cancelling IFR.
| Me. ATC, Nxxx confirms cancelling IFR.
| ATC: Advise Nxxx cancellation received.
| Me; Nxxx, ATC advises cancellation received.
| Nxxx: Thank you.
| ATC: Nyyy cleared RNAV rwy 21 approach...
