Title: 21 Jun 2018: China Airlines 5148 Runway Excursion during go-around at ORD
Post by: wiedehopf on June 21, 2018, 05:39:50 PM
So at 40 seconds in this clip and at 28:20 in the original file (14:48:20 UTC // 09:48 local time) you can hear another pilot say "Going off the runway".
At 1 minute (28:49 in the original file) in the file you can hear "Dynasty 5148 we are going around due to last minute deviation on the runway".

The runway was immediately closed for inspection, there seemed to be debris on the runway.

From this and the NOTAMS i assume this was an runway excursion.

NOTAMS
ORD AD AP WDI FOR RWY 10L OUT OF SERVICE 1806211547-1807262300 (WDI = Wind Direction Indicator // wind sock)
ORD RWY 10L/28R SAFETY AREA IRREGULAR SFC N SIDE BTN TWY DD AND TWY N1 1806211540-1807141100

NOTAMS for the approach lighting system and ILS have since been removed so i would assume they were inspected and the only damage was to the wind sock and the grass area to the left of the runway.

They landed safely after the go-around and the customary phone number was interchanged but i didn't include that in my clip.

I'm confused. :(

Dynasty was going to go off the runway so it went around?

I thnik that's it. Maybe they were headed to the left side of the runway or had a gust on the flare that moved them sideways and went around.

I'll take a look at the METAR and see how the weather was at that time.

See http://avherald.com/h?article=4ba33b1c for a nice writeup and METAR.

It's mostly speculation what exactly happened until a report is released, but by all means lets speculate:

The wording "last minute deviation" may indicate they were doing an autoland and the localizer was disturbed by the departing plane or something else.

Maybe they decided to go-around shortly before touchdown but of course you need to put in a bit of energy and they still touched down and that was with the left main gear into the grass area to the left side. (because they were not lined up correctly)
Or:
They could have bounced on landing, decided to go-around and then during the go-around deviated to the left.
That still fits with the location of the the runway excursion right at the end of the touchdown zone.


10C where they would normally land was closed at the time but i'm not sure why. (was a planned closure didn't find any go-arounds due to sudden closure)
Maybe a runway inspection or too much rain?

The China Airlines aircraft veered  off the runway into the grass and took out the wind sock. It spent the last week in the United maintenance hanger getting repaired.
