Company Policy requires an Inspection inside the Number 2 Engine Inlet after snowfall. During my inspection of Number 2 Engine inlet for snow; I discovered a bent tip on one fan blade. I contacted Company Maintenance Control; took a picture of the bent blade tip and electronically sent it to Maintenance Control. Then; I repaired / blended the fan tip blade per Company Maintenance Manual. I took a picture of the fan blade after completing the repair and electronically sent it to Maintenance Control. I accomplished this repair at night with the use of a hand-held flashlight; and the weather was very cold; approximately 15-degrees Fahrenheit. An Eddy Current Inspection of the fan blade was deferred; through Maintenance Control; because the ZZZ Maintenance Facility does not have a qualified Inspector / Technician.
A Line Mechanic reports finding a bent inlet fan blade tip on Number 2 Engine during a Snow Inspection of an MD-11 aircraft in 15 degrees Fahrenheit temperatures. After blending out the blade tip damage; Maintenance Control deferred the fan blade Eddy Current Inspection; aircraft later experienced Number 2 Engine vibrations.
