## Summary

We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model BO-105LS A-3 helicopters. This proposed AD would require inspecting the helicopter records to determine if there is a life limit for the tension-torsion (TT) straps installed in the helicopter lifting system, establishing a life limit if there is not one, and replacing each TT strap that has met or exceeded its life limit. This proposed AD is prompted by an error in the Airworthiness Limitations section of the Model BO-105LS A-3 maintenance manual. The proposed actions are intended to prevent failure of a TT strap and subsequent loss of control of a helicopter.
