## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to Eurocopter France Model AS350B, BA, B1, B2, B3, D, and AS355E, F, F1, F2, and N helicopters. This proposal would require replacing certain circuit breakers. This proposal is prompted by the discovery of the loss of electrical continuity between the terminals of an installed circuit breaker. The actions specified by the proposed AD are intended to prevent loss of electrical power to the emergency flotation gear or other optional installations and subsequent loss of the helicopter emergency flotation capability.
