Purpose of Flight:Check
Comments:This was a 2nd troubleshooting flight to understand the cause of an unknown vibration. To try and completely eliminate the vibration, we removed the two SAGA inlets on the top of the aircraft since our last "fix" we believed mitigated the vibration significantly. However, the vibration occurred again and included wings-level conditions. On the previous flight, it only occurred during bank angles greater than 20 deg. The aircraft returned in good condition although #2 thrust reverser did not deploy on landing.
