During takeoff after 80 KTS, but before V1, there was suddenly a loud bang. We felt the aircraft yaw to the right and we saw a bright flash from the right side of the aircraft. I called abort, and the first officer complied with all appropriate abort procedures. We stopped the aircraft safely without the need to declare an emergency. We taxied clear of the runway, secured the right engine, and requested clearance to taxi back to our gate. There was some confusion about our taxi clearance. This flight was the first officer leg, departing runway 31 at ZZZ. All indications during start, taxi and initial takeoff were normal. Our first indication of the problem was the engine failing! I have heard about problems with pratt and whitney 306B engines, and now have first hand experience. My concern about these engines is the reliability record. They seem to have a much higher failure rate than other turbine engines. Example: we frequently fly aircraft with maintenance carryovers on cracked turbine blades. These engines have very low time on them! Callback conversation with reporter revealed the following information: the reporter stated the maintenance action was replacement of the right engine which was a pratt and whitney 306B. The reporter said this was his first unpleasant experience with this engine and is concerned about its reliability record and high failure rate. The reporter stated they frequently fly aircraft with deferred items on engine turbine blades being cracked. The reporter said these engines have very low time and should not be subject to cracked blades. The reporter stated in a recent cursory check of the entire dornier fleet it revealed 23 catastrophic engine failures. The reporter stated the cessna citation operates the same engine, but with derated power and has no problems operating this engine.

Title: A DORNIER 328 JET ABORTED TKOF AFTER 80 KNOTS DUE TO THE R ENG CATASTROPHIC FAILURE.
Narrative: DURING TKOF AFTER 80 KTS, BUT BEFORE V1, THERE WAS SUDDENLY A LOUD BANG. WE FELT THE ACFT YAW TO THE R AND WE SAW A BRIGHT FLASH FROM THE R SIDE OF THE ACFT. I CALLED ABORT, AND THE FO COMPLIED WITH ALL APPROPRIATE ABORT PROCS. WE STOPPED THE ACFT SAFELY WITHOUT THE NEED TO DECLARE AN EMER. WE TAXIED CLEAR OF THE RWY, SECURED THE R ENG, AND REQUESTED CLRNC TO TAXI BACK TO OUR GATE. THERE WAS SOME CONFUSION ABOUT OUR TAXI CLRNC. THIS FLT WAS THE FO LEG, DEPARTING RWY 31 AT ZZZ. ALL INDICATIONS DURING START, TAXI AND INITIAL TKOF WERE NORMAL. OUR FIRST INDICATION OF THE PROB WAS THE ENG FAILING! I HAVE HEARD ABOUT PROBS WITH PRATT AND WHITNEY 306B ENGS, AND NOW HAVE FIRST HAND EXPERIENCE. MY CONCERN ABOUT THESE ENGS IS THE RELIABILITY RECORD. THEY SEEM TO HAVE A MUCH HIGHER FAILURE RATE THAN OTHER TURBINE ENGS. EXAMPLE: WE FREQUENTLY FLY ACFT WITH MAINT CARRYOVERS ON CRACKED TURBINE BLADES. THESE ENGS HAVE VERY LOW TIME ON THEM! CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE MAINT ACTION WAS REPLACEMENT OF THE R ENG WHICH WAS A PRATT AND WHITNEY 306B. THE RPTR SAID THIS WAS HIS FIRST UNPLEASANT EXPERIENCE WITH THIS ENG AND IS CONCERNED ABOUT ITS RELIABILITY RECORD AND HIGH FAILURE RATE. THE RPTR STATED THEY FREQUENTLY FLY ACFT WITH DEFERRED ITEMS ON ENG TURBINE BLADES BEING CRACKED. THE RPTR SAID THESE ENGS HAVE VERY LOW TIME AND SHOULD NOT BE SUBJECT TO CRACKED BLADES. THE RPTR STATED IN A RECENT CURSORY CHECK OF THE ENTIRE DORNIER FLEET IT REVEALED 23 CATASTROPHIC ENG FAILURES. THE RPTR STATED THE CESSNA CITATION OPERATES THE SAME ENG, BUT WITH DERATED POWER AND HAS NO PROBS OPERATING THIS ENG.
