Suosituksen perustelu
The flight documents used by the operator are based on the FCOM published by the aircraft manufacturer. Flybe Finland Oy’s ATR fleet-specific instructions are superficial as regards the TLU system. The descriptions of normal system operations and the standby system are inadequate, and the limitations caused by a fault are not satisfactorily explained.
Recommendation
Safety recommendation 4 (documentation/literature): Safety Investigation Authority, Finland recommends that the manufacturer of the ATR aircraft include in the FCOM further information on the TLU system including the limitations on the controllability of the aircraft caused by its malfunctioning.
