From an email conversation I had with licencing personnel at IAA
Q: Are the IAA still anticipating that UK applications received through the post on or around 04/09 to still be processed and issued with an Irish EASA licence in late 2020 / early 2021?
A: That is correct. Whilst the IAA will continue to process change of SOLI applications for UK licences received after 4th September 2020, the 12+ week turnaround of such applications means that it is unlikely that the exchange of licences will occur before the end of the year. This will obviously be an issue for pilots who need the surety of an EASA licence to continue flying in early 2021. For those pilots not using an EASA licence at present, the timings will be less of an issue.
