G-ISLN is currently the youngest ATR 72-500 in the Blue Islands fleet, joining in early 2019. It was originally painted in the basic Blue Islands livery, until the airlines relaunch in 2020 (like G-ISLM), when it was repainted into the updated livery.
In February the aircraft was grounded after its newly-installed left engine ingested debris at Guernsey airport. The engine concerned required parts and maintenance to return it to operation, causing long delays due to ATR supply chain issues. There were also other reports suggesting the aircraft was being used a spare parts source due to difficulties acquiring new parts. On the 17th July it was flown to Jersey for further work and eventually returned to service on the 26th.
