Lion Air
 

Lion Air runway overrun, again.
 

Although I'm not a particular fan of Avherald, I'd still suggest that it's courteous to credit the source when you're quoting from it:

Accident: Lion B738 at Gorontalo on Apr 29th 2018, runway excursion on landing

Lion Air are the runway excursion specialists - including 2 at the same airport within 24h!

No fatal accidents so far - that's not for lack of trying!

For some reason they still haven't been shut down by the Indonesian CAA.

450 metre over-run on an 8000 ft strip.
And that's through the cow paddock; sticky, cloying mud, up to your buttocks.

That takes some effort.

There is a perception in these parts that speed plays a significant role in these incidents, as anyone might suspect from the outcome.
Admittedly that perception may be influenced by the proximity of housing to the wingtips on landing.
A bit like the power stanchions out of the window of the Shin Kanzen.

It just seems that most landings seem to be much faster than you become accustomed to in other regions.
Hence the perception, whether truly indicative or not I do not know.
And, of course, high speed may be a contributor to long landings.

It would be handy to see some detail of speed from any reports on these incidents.

But, by exception, Garuda seem to have got on top of that perception; ever since the Jogyakarta over-run.

I have no idea where Avherald got that from, but the daylight photos would suggest that it was a lateral excursion, with at least some runway remaining, and not an overrun:

Stated in the article:
The perils of relying on ADS-B data to make any kind of statement about aircraft final position are well known, I thought avherald would be better than to fall into that trap.

Yes, I should have phrased it better - I was wondering where the ADS-B data supporting the overrun conclusion had come from. It's certainly not from FR24, which only captures the landing track as far as the TDZ.

Sadly, and not for the first time, Simon is way out of his depth when it comes to drawing conclusions from ADS-B data (there may be a bit of Dunning-Kruger at play here).

I'm reminded of a similar discussion about 18 months ago (Norwegian B738 at Kristiansand):

Interestingly, there's a even a reader comment in the Avherald report on the Lion Air correctly pointing out that the photo captioned "The aircraft past the runway end" clearly isn't !

You are quite right.
Your photo seems to show it off on the LH side pretty much next to the turn off for the new terminal, with the eastern end of the high ground to the south visible in the background.
Also seems to indicate that he was angling back towards the runway.

My guess would be about 6000 ft down the runway.

But I'll stick with my comment about the cow paddock.

This photo seems to show nose gear less than 1 metre from a tarmac surface, probably the runway.
Unfortunately somehat lower level than the sealed surface.

It is not inconceivable that this position may have been the result of a misguided retrieval operation.

Ops normal for Indonesia...

Watching Indonesian airline 737 and A320 aircraft landing and taking off with 15+ knot tail winds is a regular occurrence in the country :ugh:

Photo taken from the crash gate adjacent to the old terminal apron, suggesting that the aircraft had used rather less than half of the available 8,000 feet before departing to the left of the runway.

Yes. That seems about right.
I presumed that the equipment shown in a previous post was on the apron in front of the new terminal.... wrong again.

Ploughing through the slurry would have had a few noses pressed against the headrest in front.

They'll probably need to get salvage gear / craneage from Manado to move it.
Haven't checked but I suspect that airport is still closed to fixed wing.

Occupational problem. I operated into many Indonesian airports during the 1990s with B737 aircraft. At that time, there were many runway excursions. Also, at that time, there was no equipment in the country to remove any runway contamination. Apparently, some avtur or avgas was sprayed and ignited at various times in attempts to burn off any rubber deposits. Perhaps, nothing has changed?
