Requires a one-time torque check of the tail boom attachment hardware and inspection of the tail boom attachment fittings and longerons for damage, corrosion, or cracks, and security of attachment. AD also requires replacement of bolts and the associated nuts if they fail the torque check. Low torque values on tailboom attachment hardware may result in fretting or fatigue damage of the attachment bolts or tail boom fittings, which could lead to their failure and consequent separation of the tail boom from the fuselage and loss of control of the helicopter.
