Narrative:
At V1 loud bang occurred, continued takeoff with engine fail and left gear red lights on. At 800 ft noticed #1 engine N1 70% and aircraft vibration. ATC turned us toward teterboro airport and we had traffic conflicts. Verified we declared emergency and told ATC we wanted to maintain heading. We ran the appropriate checklists and planned a 1 or 2 engine inoperative landing. Engine #3 was vibrating moderately. No engines were shut down. Dumped 90000 pounds of fuel and returned to ewr runway 4R. Landing basically uneventful. No reverse on #1 and #2 engines and brakes froze up. No fire. Callback conversation with reporter revealed the following information: reporter said that #1 engine had a catastrophic failure in the turbine section related to a previously completed airworthiness directive from some time ago. The shrapnel from the engine destroyed the two front tires on the left gear which came apart and threw parts into both the #2 and #3 engine. There was also damage to the #3 hydraulic system, however it did not lose all fluid until after landing. Although no engines were shut down, the approach was made with reduced thrust on #3 to reduce vibration and idle thrust on #1 engine. The #2 engine was damaged, but operated more or less normally. All 3 engines were subsequently changed. Reporter also noted that he felt his best decision was not to reject the takeoff since it would have been questionable that a stop would have been successful with only two remaining tires on the left gear and limited reverse thrust.
Original NASA ASRS Text
Title: DC10 HAS LOUD BANG AT V1. CONTINUES TKOF WITH ENG FAIL AND L GEAR WARNING LIGHTS ON. EMER DECLARED, FUEL DUMPED AND RETURN TO LAND.
Narrative: AT V1 LOUD BANG OCCURRED, CONTINUED TKOF WITH ENG FAIL AND L GEAR RED LIGHTS ON. AT 800 FT NOTICED #1 ENG N1 70% AND ACFT VIBRATION. ATC TURNED US TOWARD TETERBORO ARPT AND WE HAD TFC CONFLICTS. VERIFIED WE DECLARED EMER AND TOLD ATC WE WANTED TO MAINTAIN HEADING. WE RAN THE APPROPRIATE CHKLISTS AND PLANNED A 1 OR 2 ENG INOP LNDG. ENG #3 WAS VIBRATING MODERATELY. NO ENGS WERE SHUT DOWN. DUMPED 90000 LBS OF FUEL AND RETURNED TO EWR RWY 4R. LNDG BASICALLY UNEVENTFUL. NO REVERSE ON #1 AND #2 ENGS AND BRAKES FROZE UP. NO FIRE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR SAID THAT #1 ENG HAD A CATASTROPHIC FAILURE IN THE TURBINE SECTION RELATED TO A PREVIOUSLY COMPLETED AIRWORTHINESS DIRECTIVE FROM SOME TIME AGO. THE SHRAPNEL FROM THE ENG DESTROYED THE TWO FRONT TIRES ON THE L GEAR WHICH CAME APART AND THREW PARTS INTO BOTH THE #2 AND #3 ENG. THERE WAS ALSO DAMAGE TO THE #3 HYD SYS, HOWEVER IT DID NOT LOSE ALL FLUID UNTIL AFTER LNDG. ALTHOUGH NO ENGS WERE SHUT DOWN, THE APCH WAS MADE WITH REDUCED THRUST ON #3 TO REDUCE VIBRATION AND IDLE THRUST ON #1 ENG. THE #2 ENG WAS DAMAGED, BUT OPERATED MORE OR LESS NORMALLY. ALL 3 ENGS WERE SUBSEQUENTLY CHANGED. RPTR ALSO NOTED THAT HE FELT HIS BEST DECISION WAS NOT TO REJECT THE TKOF SINCE IT WOULD HAVE BEEN QUESTIONABLE THAT A STOP WOULD HAVE BEEN SUCCESSFUL WITH ONLY TWO REMAINING TIRES ON THE L GEAR AND LIMITED REVERSE THRUST.
