## Discrepancy

GEN 2 OFFLINE LIGHT ILLUMINATED AT 35,000 FEET AND WE FELT LIGHT MINIMAL VIBRATIONS FROM THE NOSE AREA. AROUND 28,000’ VIBRATIONS INCREASED AND COULD BE FELT IN THE BACK RIGHT OF THE PLANE. AT THIS POINT, WE PROCEEDED TO SHUT DOWN THE RIGHT ENGINE ACCORDING TO THE CHECKLIST. DURING THE CLIMB OUT TO 35,000’ WE DIDN’T NOTICE ANYTHING ABNORMAL. ALL INDICATIONS WERE GREEN AND WITHIN LIMITS.
