Wow, another lottery win for the passengers. There are easier and cheaper ways of removing masonry. Plane did well though,

That's a laugh.....pilots claimed they were unaware of the incident. Begs the question as to why they diverted to Mumbai.

Informed by ATC. Read the link.

Folks,
Reminds me of something similar years ago, forget where, up in NW India, but an Indian Airlines B737 but a truck on a local road that passed the runway centreline.
It was a nice hot day, and as I recall, the aircraft was well over the WAT limit weight.
In the final accident report, the poor sodding truck driver was lumped with 50% of the blame for driving legally along the public road.
Tootle pip!!

krismiler 12th Oct 2018 07:19

Times of India reports 130 on board so even with a decent fuel load for Dubai and the usual excess baggage it shouldn't have been close to WAT limits on a night time take off.

They had to travel horizontally through the localizer antenna to reach that low brick wall. If you were not aware of that as the plane ploughed through, you must have been totally oblivious to anything going on around you.

"The matter was conveyed to the pilot in command. The pilot in command reported that the aircraft systems were operating normally."

Like hitting a Brick Wall!
 
So hitting the proverbial Brick Wall is no big deal!
Who would have known.
Great research.

I'm nicking this bit: "Khan reportedly has an agile style with official paperwork" :D

How high was the wall? was the gear up before hitting the wall but after hitting and taking some of the fence? so many questions....

On_The_Top_Bunk 12th Oct 2018 10:55

Did the wall not extend outwards to the main landing gear?

Was the gear up on contact?

Octane 12th Oct 2018 11:18

I don't get it either. The wall looks to be 6 ft tall max, how could the landing gear not take it out? Surely the gear could not be stowed at an altitude of 6 ft?!

kev2002 12th Oct 2018 11:29

My guess is it was the antenna that hit the wall, possible still attached to the aircraft at the time

EDML 12th Oct 2018 13:27

Seeing all the damage to the belly of the A/C well behind the main gear they where already (barely) flying with a lot of pitch. Therefore the gear cleared the wall.

short bus 12th Oct 2018 14:43

I watched a few Indian news reports of the incident on YouTube. There was a photo showing chain-link fencing stuck between the tires on the gear. Also, there are two sections of the wall missing, both approximately equal in size. The holes seemed to close together to be L/R gear though. But it was a quick glimpse.

​​​​Note, the wall was topped with chain link fence, which is obviously gone after this strike.

Also, there is a road immediately on the other side of the wall.

Simple geometry.

India has many crews who, whilst having paid for their licences, certainly didn't earn them. The corruption within the DGCA has been widely reported.

Rider320 12th Oct 2018 19:30

From what I heard At lift off the captain's seat got seat moved back from its position resulting in yoke going up and in reflex captain pushed the yoke which pushed the aircraft's nose down, resulting in these unfortunate incident.

Not a piiot here, but looking at the pic on BBC report, the belly gash looks to be situated between the L/R MLG, not further aft.

Reports suggest that it was the belly of the aircraft that hit the localizer antenna, but the question asked was what had impacted the wall, which was the rear fuselage.

I'm not sure how that would be consistent with the crew "not noticing anything wrong". (Not saying that this isn't true, just it's inconsistent with the reported crew "relaxed position" about nothing being amiss.

So the scenario is the aircraft somehow gets upset at rotation (seat movement, whatever) and ends up being far too low and rips out the belly on the antennas, then the crew yanks back and presents the belly to the wall/fence? Except there's photos purporting to show elements of the fence (atop the wall) embedded onto the gear struts. So the gear hit something roundabout then too... I think "they were damned lucky" is about all we can really conclude!

How could it pressurize with those gashes?

This is the best view I've found of the wall.

that explains a lot. Wheels hit the wall. Gash from the localiser.

Good find.

That seems to negate the earlier suggestion that the two holes in the wall were too close together to have been produced by the mains - they appear to be consistent with the 737NG's track (5.72 m).

Capt Quentin McHale 13th Oct 2018 00:53

tonytales,

By the look of damage from the existing photos on here, it is only superficial damage in and around the wheel wells and keel beam area and the fuselage pressure vessel has not been punctured/ruptured hence no loss of pressurisation (that we know of ???) By the look of the damage on the brick wall, I'd say both gears came into contact with the wall. Soooooo lucky that this was not a disastrous outcome!!!

McHale.

Anyone who flew older single engine Cessnas would know all about this.

anyone that has ever flown in India will know all about this and lots of other happenings. We don’t hear 3% of the aviation shenanigans that go on in the subcontinent. This will be swept under someone’s desk, tea money will be put in an envelope, head bobbles exchanged and another crisis averted through journalistic dynamicism, lyrical skulduggery, archaic prose and feats of executive needful sabbatical misappropriation of the dutiful duties of his excellency the Vice Chairman Minister of aviation learning knowledge and Aerodrome awareness and reporting. India don’t change, India changes you.

Can anyone run these numbers? 738, trip length 1590nm/2491km, runway length 2427m/7963 feet, OAT 83F/23C.

There is a great deal of aeroplane outside the pressure vessel.

Herod 13th Oct 2018 07:15

The picture of the wall says either a lot about the strength of Mr Boeing's aircraft or not a lot about the building skills of Indian bricklayers.

sitigeltfel 13th Oct 2018 07:33

Did the wheels actually strike the wall or did they catch the chain link wire pulling out the supports and the sections of the wall they were embedded into?

One does not exclude the other.

So many variables.
Assuming about 13T of gas, 170pax, nil wind, 26k engines, bleeds on, it would be at 35ft about 100m prior to the end of the runway using an assumed temp of 39 degrees. If they wanted to use full thrust it would be at 35ft about 400m prior to the end of the runway. V2 of about 150.
There are potentially other variables that would make quite a big difference though.
