Hello again,
Not sure how to best provide information on this, but this is an event that has occurred to me several times over 250 hours of flying this aircraft. I haven't been able to figure out why, but during cruise out of the blue the right engine will fail. After roughly a minute, the left engine follows. My initial guess was icing blocking the oil cooler leading to over-temp, but I did not observe any abnormal gauged indications prior to either failure. All switches were unmoved from takeoff position (RCS Run, SRL on, Air Start & Safe selected, Main Valve Open, Tip Tanks AUTO).
Any ideas would be appreciated.
