A Working Arrangement between UK Civil Aviation Authority (CAA) and the Civil Aviation Authority of Singapore (CAAS) was signed on 18 December 2020.
CAA approved Part 145 organisations may hold an approved CAAS Maintenance Organisation Exposition (MOE) Supplement to maintain aircraft (registered on the Singapore Aircraft Register) and engines, Auxiliary Power Units (APUs) and propellers to be installed on those aircraft.
The Working Arrangement means that UK CAA will undertake the oversight of organisations that hold UK Part 145 approval and CAAS MOE Supplement, who perform the maintenance of Singapore registered aircraft, engines and propellers to be installed on those aircraft. This means that the UK CAA will undertake the oversight of those organisations where the main base is in the UK.
