UA28 FR24

[Flightmech]

Not sure what UA 28 is doing south west of the Isle of Wight but has been doing it for an awful long time, even for a fuel dump?

[G0WBR]

Not sure but he advised the controller that he would be holding for approx 2 hours before returning to LHR. Was just burning fuel, now dumping.

[Redredrobin]

The Newark arrivals board has the flight posted as 'Diverted'

[Flightmech]

It's been holding for an eternity. Even with a tech issue requiring a fuel dump and return to LHR it should be back long ago?

[SpringHeeledJack]

From the BBC radio news, returning to Heathrow due to a 'maintenance issue'. Unusual that a pretty normal and oft experienced happening should make a mention on the news ?

[Flightmech]

Agreed. I don't know the 767 that well but unless it has an electrical bus issue that is also rendering the fuel jettison system inop so he's having to burn it? A normal airborne return doesn't take over three hours when so close to the origin?

[SpringHeeledJack]

It's most likely as you say, needs to burn fuel the old way, so they're at 12,000ft for a few hours and then RTB. From the beeb….

15;39 local, he is now descending from FL080 for LHR. After over a dozen orbits in the Isle of Wight region.

[Phalconphixer]

Landed 15.45 GMT LHR

[oldoberon]

good news - appears to have landed safely.

[SpringHeeledJack]

As of 15.53 on the ground tootling along towards T3 at LHR. Glad that it wasn't too serious, but am curious as to what it was :8

[Redredrobin]

Daily Mirror has a tweet from a passenger, who took a photo from the apron while disembarking, of left hand engine with cowl open and being looked at. May be a clue.

[KelvinD]

This aircraft appears to be suffering yet more bad luck.
Having been rescheduled as UA2056 with a departure time of 09:00, followed by a delay to 13:55, the aircraft appears still to be on the ground at 14:10.

Airborne at 10:49. Should be landing at Newark in a couple of hours time.

[Una Due Tfc]

Fuel jettison is only an option on the 767. Same with the A330, not all of them have it. Overweight landings require thorough inspections afterwards, and may result in damage to the gear and fuselage. Makes sense to burn up the fuel in a hold rather than risk a huge repair bill if it's nothing urgent.

Spotted that Dave. It seems my earlier info was inaccurate. Currently bimbling along over Nova Scotia.

[Flightmech]

Well this proves the airplane had fuel dump capability and that it was working so still doesn't explain why it was airborne for nearly 4 hours??????

Might have been waiting for an available slot. LHR usually only take unscheduled arrivals or give priority to aircraft that declare an emergency. Maybe UA didn't want all that paperwork 😂
