1. PLANNING INFORMATION 

1.A. EFFECTIVITY 

1.A.1. Helicopters/installed equipment 

Helicopters: 

- equipped with at least one of the seats listed in paragraph 1.A.2. 

and 

- on which the label shown in the Appendix is not visible to the occupants of these seats. 

1.A.2. Non-installed equipment

1.B. ASSOCIATED REQUIREMENTS 

Not applicable. 

1.C. REASON 

During certification of an energy-absorbing seat with a new Part Number, it was observed that the label 

which indicates that the space under the seats must remain free was not systematically installed. 

Objects stowed under this type of seat may reduce the efficiency of its energy-absorbing function and thus 

jeopardize the occupant's survival in the event of a crash. 

Consequently, and pending a definitive solution, Airbus Helicopters makes it mandatory to affix a label which 

indicates that nothing must be stowed under the energy-absorbing seats. 

1.D. DESCRIPTION 

Compliance with this ALERT SERVICE BULLETIN consists in: 

- preparing one or several (locally made) label(s) which indicate(s) that nothing must be stowed under the 

energy-absorbing seats, 

- affixing this (these) label(s) so that it is (they are) visible to the occupants of these seats.
