Narrative:

On sep/thu/02 aircraft was in oak on graveyard shift with a pilot write-up stating that upon landing with aircraft #1 engine in reverse power, the engine made a muffled popping sound and sounded like a compressor stall. After further trouble-shooting and researching the aircraft maintenance manual, I performed a purge of the cdp lines, ran engine at all power settings, no faults noted. Reverse power ok while using the trouble-shooting fault isolation tree in MM chart 71, at no time did it state to perform a borescope inspection. Also, performed a vsv and vbv static rig check per maintenance manual. Later that night I conferred with maintenance control and engineering and a borescope inspection was not mentioned.
