An engine inspector reports that 12 borescope plugs were removed from a pw-2000 engine and the openings were left uncovered; open to FOD for twelve hours; while inspections were accomplished and inspection write-ups were worked by the engine test run mechanics. The borescope procedure was not accomplished until twelve hours after the plugs were removed.

Narrative:
12 ea borescope plugs were removed from a pw-2000 engine; june 2009. The borescope plug openings were not covered as required per our engine shop operations manual. During the next 12 hours; an engine inspection was accomplished on this pw-2000 and 28 each; non-routine write-ups were made and worked by engine test run mechanics. During all this maintenance activity; the 12 each; borescope plug openings were uncovered and open to FOD entering the engine. The pw-2000 was not actually boroscoped until 12 hrs after the plugs were removed. This is just one example of the procedures followed by engine test run personnel. Borescope plug openings are left uncovered after every pw-2000 engine run; while maintenance (work) is done on the engine. I have brought up this issue to my inspection supervisor; inspection manager; test cell manager; FOD manager; and the director of engine maintenance on several occasions; but the problem remains unsolved. The engine mentioned above was made serviceable june 2009.
