Airworthiness Directives; Eurocopter France Helicopters

Resumo

We propose to adopt a new airworthiness directive (AD) for Eurocopter France (Eurocopter) Model AS350BA helicopters with certain AERAZUR emergency flotation gear container assemblies installed. This proposed AD would require replacing each affected emergency flotation gear container assembly (container assembly) at specified time limits based on the date of manufacture. This proposed AD is prompted by a recognition that container assemblies with an intended operating limitation of 10 years may not have been replaced because the limit is no longer recorded in the Maintenance Program. The proposed actions are intended to prevent failure of the emergency container assembly due to age and subsequent damage to the helicopter and injury to the occupants after an emergency water landing.
