Eastern has had technical issues with both E170s. G-CIXV which was operating for BA CityFlyer from LCY went tech on 10/7 and positioned to Amsterdam, presumably for attention. It is now back at LCY having returned today.
G-CIXW which was at LGW positioned to London City on 11/7 to cover for G-CIXV, however it went tech the following day! According to FR24 it positioned to Lisbon, again presumably for attention.
For information Eastern also seem to have a lot of crew or technical issues with the Isle of Man based Saab 2000 G-CIEC which operates for BACF at present, with a number of cancelled flights.
