OZ 204 Diverted Back to ICN 7/8/2018?

Is there any convenient way to learn why OZ 204 returned to ICN on 7/8/2018? I would imagine this kind of thing happens from time to time, and it would appear that something needed a repair, as there were two OZ 204s departing within 30 minutes of each other on 7/9. Just curious...

Best way to find out your curiosity is to contact Asiana directly, if you are so curious and let us know what you have found out from them.

I take it you have some kind of paid subscription to Flightaware?

I used free flight aware to identify asiana flights that are late in the past 3 days

then went to expertflyer(have paid subscription) to pull up those raw text details. Expertflyer only provides asiana data up to past 3 days, not all airlines report data (or this level of data) to expertflyer

From an item on 'The Aviation Herald" :

Incident: Asiana A359 over Pacific on Jul 8th 2018, abnormal tyre pressure indication

By Simon Hradecky, created Monday, Jul 9th 2018 22:05Z, last updated Monday, Jul 9th 2018 22:05Z

An Asiana Airbus A350-900, registration HL8078 performing flight OZ-204 from Seoul (Souh Korea) to Los Angeles,CA (USA) with 307 people on board, was enroute at FL350 about 90 minutes into the Pacific crossing about 600nm east of Tokyo (Japan) when the crew decided to turn around and return to Seoul due to an abnormal tyre pressure indication. The aircraft descended to FL340 for the return and landed safely back in Seoul about 3.5 hours later.

The airline reported the crew received an abnormal tyre pressure indication. A replacement aircraft took the passengers to Los Angeles the following morning.

A replacement A350-900 registration HL7579 reached Los Angeles with a delay of about 12 hours.

Interesting. I had searched for the tail number but did not find that article.
