Summary
Requires inspection and applicable corrective action(s) to ensure that the retaining ring is present in emergency floatation systems (EFS). Prompted by a reported occurrence of a missing EFS retaining ring on the connection between the supply hose and the central supply coupling of the EFS inflation system during a maintenance check of a helicopter. Absence of this ring could cause incorrect inflation of the floatation bag of the EFS in case of activation, EASA said.
