    Abstract: A method of maintaining a gas-turbine engine (20) is provided. The method includes the steps of removing a conduit (111) from the gas-turbine engine (20), installing a temporary oil filter (160) in place of the conduit (111) in the gas-turbine engine (20), and starting the gas-turbine engine (20) with the temporary oil filter (160) installed. A fan-drive gear system (112) is also provided and comprises a journal bearing (118), a main oil pump (104) fluidly coupled to the journal bearing (118), a main oil filter fluidly coupled between the journal bearing (118) and the main oil pump (104), and an auxiliary oil pump (124) fluidly coupled to the journal bearing (118). The auxiliary oil pump (124) may be configured to supply oil to the journal bearing (118) on startup. An auxiliary oil filter (160) may also be installed between the auxiliary oil pump (124) and the journal bearing (118).

    Abstract: A method of repairing an integrally bladed rotor (100) includes removing a portion of the integrally bladed rotor (210) to create a void in an airfoil, completely filling the void with a single replacement material (220), and laser shock peening the replacement material (252). Laser shock peening the replacement material imparts mechanical properties in the replacement material substantially the same as those in the forged material.
