Plane was arriving from Chicago to pick up a load of lobsters for China early Wednesday November 7 when it ran off the runway. Damage includes collapsed nose gear, engines 2 and 3 sheared off and a buckle in the fuselage near the wing.

A Skylease Cargo Boeing 747-400, registration N908AR performing flight GG-4854 from Chicago O'Hare,IL (USA) to Halifax,NS (Canada) with 4 crew, landed on Halifax's runway 14 (length 2350 meters/7700 feet) at 05:06L (09:06Z) but was unable to stop before the end of the runway, overran the end of the runway, went down a slope and through the localizer antenna and came to a stop about 200 meters past the runway end. The four crew received minor injuries, the aircraft received substantial damage with all gear collapsed, engines #2 and #3 separated, engines #1 and #4 damaged and creases in the fuselage skin.

The ATL comment that it was the second over run for the plane AND pilot was interesting.

With patience and saliva. (and confirmed by Google translate)

Must be some crazy Argentinean colloquialism.

For 747 watchers, here are additional details.


Crews take apart cargo plane that overshot Halifax runway 17 November

Halifax airport returns to normal operations in the wake of Boeing 747 runway overshoot 9 December

The Halifax Stanfield International Airport has resumed normal operations a month after a plane overshot a runway, taking out navigational equipment and leaving a trail of debris in its wake.

Still to be replaced are some approach lighting towers, which help guide pilots to the runway, but airport spokeswoman Theresa Rath Spicer said they aren’t affecting operations.

She said approach lighting is only needed when landing in darkness or poor visibility, so in those conditions, the airport’s other three approaches are available.

Following the incident, the runway remained closed for nearly two weeks before reopening on Nov. 20, though without its full navigational capabilities.

Rath Spicer said the SkyLease Cargo plane also took out a large localizer antenna that was part of a navigational aid, but it has been replaced in the last couple of weeks.

She also said officials have removed and disposed of the contaminated soil and are working to backfill and grade the area in order to extend the runway-end safety area – a project that began before last month’s incident.

A runway-end safety area is a buffer strip that extends past the end of a runway. It gives planes extra stopping distance and can reduce damage and risk to passengers in the event of an overrun.

Transport Canada requires an extra 60 metres of prepared surface at the end of each runway, though it recommends an additional 90 metres for a total margin of 150 metres.

I find it disconcerting that one of the most important aspects of this story is being grossly underreported: the fact that a number of lobsters apparently are going to be able to celebrate one more Christmas than they otherwise would have.

That is a remarkably perceptive point and shows how badly "identify politics" has affected the media. Plenty of coverage of misogyny or relative genderism, but not one peep for lobster rights.

The sound of the digger arm as it crushes the skin of the aircraft is both satisfying and unpleasant. It's very much like the sound of the crushing of many aluminium cans (surprising that...)

This was also a somewhat underreported aspect of the slight malfunction that occurred aboard RMS Titanic. Said malfunction, while problematic for many of her passengers, was a veritable blessing for most (if not all) of the lobsters in her kitchen.

Only one mention of lobsters:

Runway overshoot that destroyed 747 cargo jet in Halifax caused by many factors: TSB


HALIFAX -- Confusing runway instructions, an unexpected tailwind and crew fatigue were factors that contributed to a 2018 runway overshoot that destroyed a Boeing 747 cargo jet at Halifax Stanfield International Airport, the Transportation Safety Board of Canada says.

In an investigation report released Tuesday, the independent agency also cited insufficient braking on a wet runway, noting that the aircraft was wrecked as it slid down a grassy embankment 270 metres past the end of the runway. All three crew members received minor injuries, but the sole passenger -- a deadheading pilot -- was not injured.

The massive aircraft, operated by Sky Lease Cargo based in Miami, Fla., started its ill-fated flight at O'Hare International Airport in Chicago early on Nov. 7, 2018. The crew had planned to pick up live lobsters in Halifax, which were destined for markets in China.
But there were problems even before Flight 4854 took off.

The board's investigation found that a confusing notice to pilots -- known as a Notice to Airmen or NOTAM -- led the crew to wrongly believe the longer of the two runways in Halifax -- Runway 23 -- was not available for landing. As a result, they planned to land on Runway 14, which is 2,347 metres long.

As the aircraft approached the runway in the dark just after 5 a.m., air traffic control failed to tell the crew about the availability of Runway 23, although an automated information system was broadcasting that information, the report said.

Less than 90 seconds before the jet crossed the threshold, the crew realized there was a tailwind to contend with, as well as a rain-slicked runway. Airplanes typically take off and land into the wind, which offers pilots more lift and, as a result, more control. But tailwind landings are possible within certain limits.

"Upon landing, a series of events prevented the aircraft from decelerating as expected and caused the aircraft to drift to the right of the runway," the report said.

The document said that for some unknown reason, the thrust lever for the No. 1 engine was moved forward of the idle position, causing the speed brakes to retract and the autobrake system to disengage. Those changes increased the distance required to bring the aircraft to a stop.

"The pilot monitoring was focused on the lateral drift and, as a result, the required call-outs regarding the position of the deceleration devices were not made," the report said.

The brakes were applied eight seconds after touchdown, but maximum braking effort did not occur until 15 seconds later, the report said. At that point, the 183,500-kilogram jumbo jet was about 240 metres from the end of the runway

"From this position, it was not possible for the aircraft to stop on the runway," the report said.

As the plane skidded down the embankment, it hit a large localizer antenna, its landing gear collapsed, two of its four engines were torn off and there was a small fire under the tail section, caused by a severed engine.

The board identified two risk factors for fatigue that would have degraded the crew's performance: the early morning timing of the flight and insufficient time for restorative sleep in the 24-hour period leading up to the overrun.

Because of "acute sleep disruption" and the timing of the landing, "the performance of the flight crew at the time of the accident would likely have been degraded by fatigue," the report said.

"However, the crew did not report feeling fatigued at the time of the occurrence."

In late 2018, the safety board said there had been an average of nine overrun incidents every year in Canada since 2013.

The safety board also noted that the uneven terrain where the aircraft came to rest was beyond the runway's 150-metre runway end safety area, which is designed to reduce the risk of damage to aircraft that land short of the runway or overshoot it.

The report said that in 2007, the board recommended Transport Canada require all runways longer than 1,800 metres to have a 300-metre runway end safety area or a means of stopping aircraft that provides an equivalent level of safety.
