The FAA is accepting comments until August 16 on a proposed Airworthiness Directive that would affect as many as 3,572 TFE731-2 and -3 turbofans on U.S.-registered aircraft. If the measure is enacted, the engines’ low-pressure turbine stage 1 disks would have to be repetitively checked for fatigue cracks. An estimated 1,900 of those engines would require disk replacement under the proposed AD.
