Sriwijaya B 734 Runway Excursion - W/O For Sure

Fri Jun 01, 2012 11:48 am

And this is the number ?
5 ?
8 ?
I'm really lost counting how many 737 were damaged beyond repair in Indonesia in the last years.
And some common factors arise in a lot of this accidents : Bad Weather, and runway excursions.

Indonesia needs to work really hard in some cultural issues, the bad weather is a factor you can find in any place of the world, but Indonesia seems to be the only place capable of killing aircraft at this incredible rate.

Indonesia indeed is the world´s no.1 737-killer. Seeing this plane is 22 years old, a write-off is highly likely.

Quoting Gonzalo (Thread starter):

I count at least 10 in the past 10 years. But likely more as some old ones surely have been wo/wfu unreported to the wider public after minor mishaps.

Get-there-itis, is still the major cause of accidents here.

Some airlines need to work reeeeeaaaaalllly hard on this!

The problem is that with some airlines, the current pilot shortage is being taken advantage by some group of pilots to act like gods... Unless airlines are willing to lose some of them (by catching them doing their bad habits and telling them to "change or move out"), this will continue.

Other airlines have been able to do this... the rest need to do the same!

In this case... They were approaching runway 15 on ILS with 600m visibility only (minima is 1200m) and wind was 230/22kts, and wet. I dunno why some still think it's OK to do so, especially with the runway only 30 meters wide instead of the standard 45m and 60m.

It seems that the accident investigation report is going to be an interesting yet boring read at the same time.

Definitely Get-there-itis... or GoAround-o-phobia    

At least this time no body paid with blood the reckless attitude of this crew.

I'm not jumping to conclusions as to whether or not they acted reckless or not, although suspected so.

But airlines here need to put at least a trigger based FOQA system (installed at GA, QZ, RI and JT), and not just rely on report based FOQA.

Just an observation, but from the pictures, it does not appear that the 'lift dumpers' on the top of the wings deployed. I wonder if the crew failed to arm them and the aircraft 'hydroplaned down the runway!

Just stow them after you stop.   

When you try to land on 22kt crosswind on 30m wide runway... U're asking for directional control problems... (and runway is less than 2300m long). Being wet, there's always that urge to put the reversers at high power... reducing directional control...

I don't know specifics of the 737 but in an evacuation situation you would expect to see spoilers down. Imagine people escaping out the overwing emergency exits onto the wing with spoilers all still up! Also with many aircraft once the hydraulics are unpowered the spoilers retract by themselves.

Speedbrake lever down is the 2nd item on the QRH evacuation checklist. So they should be down. On the 737 the spoilers don't retract automatically with hydraulics off. They will bleed down over time, some quicker than others, could be seconds or hours.
