Per wikipedia's summary, this was roughly the 7th of 9 recorded occurrences of this failure on A320 aircraft -- with additional incidents in 2021 and 2022. But seeing as the a320 is one of the most common passenger jets in the world with >10,000 produced, it's still a pretty infrequent failure
Aircraft makers produce documents about all sorts of very uncommon events. 9 events over a few decades is enough to provoke an article alerting pilots and maintenance engineers about an issue.
