Narrative:

During a takeoff to meet the company requirement for currency; the starboard engine lost 25% power at 100 feet AGL. The climb was continued to pattern altitude of 900 feet MSL. Upon observing a loss of oil pressure; a precautionary shut down of the starboard engine was completed. Since there was no engine failure and the shutdown was precautionary; no report was filed since it was not required by the far. Maintenance investigation revealed a 1 1/2 inch wide; 7 inch long; piece of masking tape in the oil inlet screen causing the loss of oil pressure indication. Further investigation revealed no immediate damage to the aircraft engine; however a mandatory service bulletin by lycoming does require an engine tear down for an event such as this.
