(j) Compliance Time Definitions for Model 767-2C The definitions in paragraphs (j)(1) through (5) of this AD apply to this AD. (1) A "flight cycle" is an operation by an aircraft that is initially stopped on the ground, departs in flight, attains a maximum above ground level (AGL) altitude greater than 5,000 feet relative to the runway, lands on a runway, and stops on the ground. A flight cycle may include one or more touch-and-go cycles. (2) A "touch-and-go cycle" is an operation by an aircraft that lands and departs on a runway without stopping or exiting the runway and is immediately followed by a short flight with a maximum AGL altitude of 5,000 feet relative to the runway. (3) "Total accumulated cycles" is the sum of the accumulated number of flight cycles, accumulated missed approaches, and the accumulated number of touch-and-go cycles. (4) A "missed approach" (or go-around) is an aircraft landing approach that is discontinued and proceeded by a climb-out for any reason without landing gear touching the runway and is either immediately preceded by or immediately followed by a short flight with a maximum AGL altitude of 5,000 feet relative to the runway. Any flight operation not meeting this definition is considered a flight cycle. (5) "Cumulative" cycles are total cycles since new.
