To the right of this text is a list of the effected Aircraft Models and according serial numbers. This AD was prompted by information provided by Textron. The information states that a washer assembly may provide premature torque indication that could lead to cracking of the wing fitting a washer assembly provided with premature torque indication could lead to cracking of the wing fitting. The FAA is issuing this AD to prevent such fatigue cracks. The unsafe condition, if not addressed, could result in failure of the forward lower wing fitting, which could lead to wing separation and loss of airplane control. Please read these important documents. If you have questions on this AD and would like to discuss please give us a call. You can also contact us for scheduling and pricing with the information listed below.
Under similar model restraints there is an additional correction that must be made under the SB 57-01 that speaks on incorrectly sized washers that were installed with the Wing Bolts.
