1.D. DESCRIPTION 

Within the scope of new customization work consisting in installing a VIP bench seat, EUROCOPTER 

noted that the load strength of the fixed parts of the installation did not meet the statutory 

requirements. 

EUROCOPTER has validated the return to conformity of the installation, and a modification enabling 

the bench attachments on the cabin floor to be strengthened in order to re-establish the 4-seat 

capability, will soon be proposed to you. 

Pending this modification, EUROCOPTER limits the use of VIP seat benches to the 3-seat 

configuration.
