G/A (Go Around) due to not breaking out at minimums in BZE. Held at BZ901 NW of the airport. After about 15 minutes a flight made it in. A B737 ahead of us went missed approach. We landed after breaking out just above minimums (lower than 100 ft above minimums). During the entire hold and subsequent approaches; several aircraft were requesting Special VFR arrivals. Field conditions were 2500 meters and the ceilings were 300 to400 ft. We landed on the second approach. Used the turn button on the south side of the runway; about 6000 7000 ft from the approach end; to turn around. Used TCAS to see how for out the next arrival was. Noticed a target +300 ft just west of the airport. Initially I thought he was holding because there was a lack of closure. That's when it got crazy; suddenly he breaks out of the rain shower heading towards us. Tower makes a non-directive statement about us still being on the runway. Cessna Caravan says 'I have the aircraft in sight' and continues his descent right at us. Immediate mental calculation of open grass area to our left. I try accelerating but realize we'll never make the turn off in time. FO (First Officer) broadcast 'we're still on the runway!' Aircraft continues descent towards us. FO says for the second time (internally) 'what's he doing? He's still descending!' I try flashing landing lights (under wing; probably worthless effort; all lights were still on). I transmit 'AIRCRAFT IS STILL ON THE RUNWAY; GO AROUND!!!' Aircraft stops descent at approx 50-75 ft. FO 'why isn't he climbing?!?!' I start maneuvering aircraft right of centerline to get more separation between the vertical stabilizer and the aircraft. At this point I'm not sure if he's going to land ahead of us; try to land over us; or is just buzzing us. Dumb. No; beyond dumb. Aircraft on the go around drifts left of centerline towards us and I stop my attempt to gain lateral separation. He goes right over the top of us about 50 to75 ft. We haven't even reached taxiway C so we're 4000 ft(?) from the end of the runway and he's less than 100 ft directly over the top of us. We clear the runway. ATC never said a word directing a go-around (that I recall). Cowboy aviation at its worst.  It was a Cessna Caravan that checked in as we were on the approach and was told that it was #7 for the approach. The aircraft in question wasn't cleared by ATC to attempt to land. He did it on his own. And the tower controller didn't order a G/A. And when the responding aircraft said 'I have the airplane in sight'; while continuing to descend; it bordered on bizarre. ATC did nothing. The FO spoke up directly to the approaching aircraft. That didn't stop his descent. At that point I sternly ordered a G/A. Thankfully he listened. A major lesson learned; I will recommend to anyone that asks that they should avoid that operator at any cost. Need positive ATC control. Can't have local pilots operating as they choose to. Lack of safety oversight.
Air carrier Captain executed a go-around at minimums after an ILS approach to Runway 7 at MZBZ and enters holding. The second approach is successful; but with no full length taxiway; a turn around and back taxi is required to clear the runway. During the back taxi a Cessna Caravan commences an approach without clearance and is reluctant to go-around when the air carrier aircraft is detected on the runway.
