Unsafe Condition
Analysis of service data has shown that the effect of touch-and-go and overshoot on life cycle counting is higher than anticipated. Therefore, the life cycle counting method for touch-and-go and overshoot as defined by the Time Limits Manual needs to be changed to reflect this higher effect on life.

Required Actions
Revise the airworthiness limitations section (ALS) of the operators' approved maintenance program to remove the requirement to record each touch-and-go or overshoot as 1/5 of a flight cycle on engines installed on airplanes used for Pilot Training. Revise the ALS to add a requirement to record each touch-and-go or overshoot as 1 flight cycle to the life of all critical parts and the fan blades. Within 120 days, determine the number of touch-and-go's and overshoots experienced by each individual critical part since entry into service for Pilot Training and recalculate the accumulated flight cycles if the number of touch-and-go's and overshoots is one percent or more of the total flight cycles on the critical part.
