1.C. REASON 

To prevent unwanted and/or failed deployment of the emergency flotation gear. 

This ALERT SERVICE BULLETIN will form the subject of an EASA Airworthiness Directive. 

1.D. DESCRIPTION 

EUROCOPTER has been informed of an uncontrolled deployment of the emergency flotation gear (not 

armed) in flight on an EC130 helicopter. 

The flight crew heard a detonation followed by heavy vibrations and noticed that the LH and RH 

emergency flotation gear floats were inflating. 

The investigations carried out on the emergency flotation gear control system, revealed that a wire was 

damaged inside the flotation gear unit "1G". 

This wire was damaged due to interference with the screw securing cable 1GR19E (k, Figure 5) lug to the 

busbar. 

Consequently, pending a modification to the said flotation gear units, EUROCOPTER renders the check 

of flotation gear unit "1G", mandatory. 

1.E. COMPLIANCE
