Abstract
In one form a maintenance device includes a flexible member with an inspection end sized to be inserted through an inspection port of a workpiece such as a gas turbine engine or a blade of a gas turbine engine. The maintenance device includes a directed energy member that in one form is configured to produce a double pulse laser with an interval time between a first one of the pulses and a second one of the pulses greater than the time of either the first one of the pulses or the second one of the pulses. The first one of the pulses is sufficiently powerful to produce a quantity of debris upon irradiation of the workpiece. The debris produced from the first one of the pulses can be evaporated by the second one of the pulses to eliminate and/or reduce a recast layer on the workpiece.
