### 1.C. REASON

During certification of an energy-abs orbing seat with a new Part Num ber, 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 t he efficiency of its energy-absorbing function and thus

jeopardize the occupant's surviv al in the event of a crash.

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

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