2 777 SQ si urtano a SIN durante il taxi

[landingFCO]

Pare 2 777-200ER uno diretto a Roma e l'altro a Copenhagen


Planes hit each other at Singapore airport

August 5, 2007 - 6:04PM

Two Singapore Airlines planes hit each other's wings while preparing for take-off at the city-state's Changi Airport but no one was injured, the carrier said in a statement today.

"It is reported that the wingtips of two aircraft came into contact while both aircraft were taxiing at low speed," company spokesman Stephen Forshaw said.

Both Boeing 777 aircraft suffered minor damage in the accident early yesterday morning and the passengers were transferred to other aircraft for their flights to Rome and Copenhagen.

The airline gave no details on the number of passengers who were onboard when the incident occurred.

Forshaw said an investigation was under way with pilots of both aircraft assisting the relevant authorities.

Capita....
immagino che le due macchine sia state lasciate a terra.
Come ha fatto SQ ha mandare cmq altre macchine a Roma e Copenaghen?
O forse ha riprotetto i pax su altri vettori?

Sapevo che SQ ha uno shortage di macchine in questo periodo.

Da quanto si capisce dall'articolo sembra SQ abbia sostituito le macchine danneggiate con altre 2 per effettuare le rotte su FCO e CPH, non mi sembra si dica siano stati riprotetti su altri voli, anche se comunque l'articolo in questo non è molto esplicito.
Magari hanno mandato una macchina diversa da quella originariamente programmata? Non so un 77W o 744 al posto del 772? E' una mia ipotesi, anche perchè non deve essere facile trovare all'istante altri 2 B777-200ER da sostituire.

E' successo da poco e quindi i voli sono in corso oppure e' storia di ieri?

a quanto si sa sono stati messi su dei 777 che erano in attesa, però certo sono previsti ritardi nei prossimi giorni. Non so però se fossero 772 configurati L/H o regional (se nn sbaglio tutti i 772 di SQ sono er, anche se SQ si ostina a chiamare non-ER quelli cfg regional). Sicuramente non sui 773 non ER.... forse sui 773ER.

oltre al CPH e al FCO direttamente coinvolti, 2 altri voli sembrano aver accumulato parecchio ritardo ed in conseguenza di ciò anche i relativi voli di rientro.

il FRA-JFK e lo Zurigo.

L'articolo è di oggi, ma sembra che i voli coinvolti nell'incidente siano quelli di ieri che infatti hanno viaggiato con circa 3 ore di ritardo (sia FCO che CPH).


04th August 2007 - Saturday - Flight Number SQ352 / Aircraft (B777-200)
Airport Scheduled Time Actual Time Estimated Time Status
Departure From Singapore (SIN) 01:00 03.53 Departed
Arrival In Copenhagen (CPH) 07.55 10:29 Arrived

04th August 2007 - Saturday - Flight Number SQ366 / Aircraft (B777-200)
Airport Scheduled Time Actual Time Estimated Time Status
Departure From Singapore (SIN) 01:00 04:29 Departed
Arrival In Rome (FCO) 07:45 10.52 Arrived


Oggi invece SQ è atterrata a FCO con 15 min d'anticipo mentre non sono previsti voli su CPH.

Il FRA-JFK, però, è un 747.

ken.... infatti io ho parlato di voli ke hanno accumulato ritardo
scusa se nn s capiva dal messaggio.... credo che sia dovuto al fatto che (forse) questi altri due velivoli erano in una zona più interna del tarmac dal quale non si è potuto farli muovere regolarmente fino a rilievi ultimati.
.... è un'idea ipotizzata sul momento e la vendo per quello che vale.

BOTH planes were readying themselves for take-off at Changi Airport.

One was headed to Rome, and the other, to Copenhagen.

But at about 1.10am yesterday morning, the wingtips of two Boeing777 aircraft operated by Singapore Airlines clipped each other.

There were passengers on board both planes at the time, but there were no injuries. The planes were 'taxiing at a low speed', said an SIA spokesman.

It is not known whether the planes were carrying a full load but the 64m-long Boeing777 with a wingspan of 61m can take a maximum of between 300 to 450passengers, depending on seating configurations.

As a result of the accident, the wingtips of both planes suffered minor damage and both flights were delayed by three hours as SIA prepared alternative planes for flights SQ366 (to Rome) and SQ352 (to Copenhagen).

SIA spokesman Stephen Forshaw told The New Paper on Sunday that one of the planes was running on its own engines at the time, while the other was being pushed back out of a gate by a tow truck, with its engines switched off.

The cause of the accident is still unclear, but MrForshaw said investigations have already begun.

'The pilots of both flights are assisting with those investigations,' he said.

'It is too early to identify the cause, but Singapore Airlines is cooperating fully with the Transport Ministry to identify any and all the factors involved in this incident'.

He added that the aircraft involved will return to service after inspections and repairs to the wingtips.

What could have caused the accident?

A veteran pilot told The New Paper on Sunday that this is rare, with vehicles so large and with so many pairs of eyes from the pilots themselves to the ground crew on the lookout.

The pilot, who spoke on condition of anonymity, said he had heard of only very few similar accidents in his two-decade-long career.

'There have been close calls, but even so, not with SIA aircraft and not at Changi Airport.

'For SIA, even hitting a taxiing light is a big offence for pilots.'

He said there are more than adequate checking procedures at Changi Airport to ensure a wide enough berth is given to all planes, as long as there is no 'breakdown in communication'.

As a standard rule, the pilot explained, the plane with its engine running would have the right of way while taxiing. The other plane on tow, with its engines switched off, would have to wait until the first plane passes.

'Air control would tell the first plane to proceed to the runway, while instructing the pilot in the second plane to stand by.

'Once the first plane passes, air control tells the second plane to proceed.

'At that point, the pilot in the towed plane will inform the ground engineer in the tow truck to proceed with pushing the aircraft out of the bay and into position.

'The ground engineer replies with a confirmation of that information, and instructs the pilot to release the plane's brakes.

'The tow truck then pushes the plane out backwards by its nose,' he explained.

He gave three possible scenarios that could have led to such an accident, based on how operational procedures could have failed.

The possibility of any plane moving onto a path other than the one it is designated to is virtually impossible, he stressed.

At night, green taxiing lights guide each plane to the runway, showing exactly where the plane should proceed. The lighted path changes according to the path each plane should proceed on.

# Scenario 1

Air control tower gives wrong instructions to one of the pilots.

# Scenario 2

One of the pilots mishears the instructions from the air control tower. For example, he could have been told to stand by, but proceeded instead.

# Scenario 3

Ground engineer mishears instructions from pilot of towed plane. But this is unlikely as pilot has to release brake before aircraft can be towed.
