Narrative: A friend and I were doing a flight in the [twin] Piper to go out and perform instrument approaches. We had just finished our run up and received our clearance from Clearance Delivery and were holding short of the runway. There is taxiway maintenance at the airport and a NOTAM in effect that the taxiways north of the FBO were closed and Back-Taxi operations were in effect. The runway in use was Runway XY. There were approximately 3-4 other airplanes in the pattern either taking-off; in the pattern itself; landing; or taxiing not including myself. As we waited our turn to back taxi; a plane could be heard on the radio as 'on a 45 deg entry into the downwind for runway XY' another plane was finishing his back-taxi and was announcing take-off roll. At this point in time; a Cirrus announces a 10 MILE RIGHT BASE for a straight in final for runway XY. (The traffic pattern is a left hand traffic pattern). Another airplane starts his back taxi while the airplane in the pattern announces midfield downwind. Upon the back-taxiing plane reaching the end; the Cirrus reports 6 miles straight in final to follow the traffic on downwind. A plane departs and the downwind traffic calls left base to final for XY. Once that plane lands; I start my back taxi down the runway. The Cirrus calls 3 mile straight in final for runway XY. About 3/4 of the way down the runway; I see the Cirrus on what appears to be a 'short final' yet he calls 'Cirrus on a 1 mile final'. Cirrus says to me 'you better hustle' and 'are you going to get off the runway?' I reply that the taxiways are closed. He says 'well then what are you doing? Get off the runway!' I respond by saying 'why can't you enter the pattern like everyone else?' The Cirrus then appears to be continuing his descent and I am afraid he is either going to land on-top of me or over-top of me. He arrests his descent at about 100 feet and 'buzzed' me down the runway and says over the radio 'I'm on an IFR arrival!' I tell him 'sorry; but this is a busy airport and we're all doing the best we can with the back-taxi operations.' He responds by saying; 'yeah; well you all can wait for me to land; I called like 10 times' This incident follows a nearly identical incident that I was not a part of; but observed; with the same Cirrus 2 weeks prior with solo students in the pattern. In hind-sight; maybe I could have delayed my back-taxi a little longer; however; the Cirrus was doing a non-standard 10 mile right base entry into a left hand traffic pattern; and performing a 6 mile straight-in to land to a full traffic pattern with back-taxi operations in effect.




Synopsis: Flight instructor reported a Cirrus performed a non-standard arrival into a busy non-towered airport while back-taxi operations were active; creating an unsafe situation.
