Flight returning to Newark after engine problem From Susan Candiotti, CNN National Correspondent updated 7:25 PM EDT, Sat August 18, 2012 STORY HIGHLIGHTS NEW: Witnesses report fire in engine United flight was taking off for Berlin FBI: Piece of tire flew into Boeing 757 engine New York (CNN) -- A United Airlines flight was returning Saturday evening to Newark Liberty International Airport after a tire blew during takeoff and flew into an engine, FBI spokeswoman Barbara Woodruff said. Flight 96, a Boeing 757, reported a problem in its left engine after it left New Jersey for Berlin, said Federal Aviation Administration spokeswoman Kathleen Bergen. The engine was operating properly and the plane was burning fuel before landing, according to the FAA. Eyewitness Keisha Thomas, who was traveling on the New Jersey Turnpike, said she witnessed fireballs near a wing at about 6:25 p.m. Thomas heard a loud sound, describing it as "pow, pow, pow." The plane was circling the airport, she said. Djenaba Johnson-Jones, who lives near the airport, said she heard an unusual noise and saw fire, but not smoke, coming from the aircraft's left engine. Eyewitness Dennis Ostolaza said he heard a "propeller sound" akin to a military helicopter as the airliner gained altitude after takeoff, with "black smoke and fire spitting out of the engine." Looks like they are holding to burn off fuel: FlightAware |
Scenario sounds very similar to the Concorde accident in Paris

Landed safely... crew was able to restart affected engine.
I'll be interested to find out if this was a main gear tire, and the explosive force was enough to put rubber shrapnel ahead of the engine intakes... Or sent rubber up the tailpipe... or if it was a nosegear failure. |
Not unheard of for a main gear tyre to shed pieces forward, aft, upwards, some of which bounce around and may be ingested into an engine causing fan damage similar to a bird strike.
Again not at all unusual for a damaged engine to emit pops, flame spurts and then smoke out a tailpipe. Pilot shuts down affected engine, and makes an airturnback as expected. No comparison with the Concord event on several areas. fodder for spectators corner :) |
It is possible for a main gear tyre to shed tread which may enter an engine intake. This may or may not cause an engine surge which may or may not auto-recover.
It is also possible for tread to enter the intake and damage fan blades and for the crew to have no indication of fan damage until after arrival at destination. |
At least the FBI's on the case.:ugh:
|
did it occur to anyone that the tire ingested into the engine was from another plane? while I suppose a nose tire might find its way into the engines of a 757, a main gear tire is much less likely to do so.
On the DC9 we did worry about a blown tire getting ingested into an engine...for obvious reasons...but a 757? |
One might be surprised at the distance FOD can be blown into an intake...they suck gobs of air, and not all from the front......
|
a main gear tire is much less likely to do so. The weather at Frankfurt was windy. The engines were windmilling. No one noticed -except for an alert ground engineer - that there was an odd shadow rotating with the fan. He stopped it rotating and, to cut a long boring story short, we were just outside vibration limits to go. Sorry guys. In the past, I've had a bit of a go at Frankfurt but this ground engineer was the only one of FE, pilot, Gnd Eng who noticed the damage. :ok: |
Isn't restarting an engine after suspected foreign object ingestion a bad idea?
Presonally, I have never crossed the pond in a narrow body and I'm intending not to in the future, even if there are probably no statistics to back this up. |

If they were over the oceans on ETOPS or over high terrain, then I reckoned it would be prudent to attempt restarts on the afflicted engine. Anyway, a good outome...the crew did a great job! |
are we not making a stretch assumption that they actually restarted the engine ?

...are we not making a stretch assumption that they actually restarted the engine ? The source for the burst tire is the FBI. Given the relative aviation expertise of those two agencies, we should probably question the burst tire as a more suspect assumption than the engine restart. :} Anyway, you can read the AvHerald report and place your bets accordingly.... Incident: United B752 at Newark on Aug 18th 2012, blew tyre on takeoff, both engines "red" |
pattern_is_full, thank you for the link to Aviation Herald. I apologise for my earlier misgivings about the crew restarting the afflicted engine. I now realise why they had good reasons to do so. Top marks to the crew for a superb job done. Bravo!
