Hello all, Question for bravo owners.
Yesterday I made a 3.5 hr flight from Cheyenne wy to Boise Idaho. I was at gross on takeoff. My final altitude was 20K. My climb out setting are 34/24 and lean TIT to 1410 seeing CHT <380, Cowl flaps open and cruse climb at 120kts. I was climbing through 12k when I felt a vibration which felt like it was coming from forward. it was fleeting and only lasted a second or less. needless to say my pulse rate went up over 100 instantly . I immediatly gave the red knob a good twist to the right cooling TIT to 1350 and my eyeballs were fixed on the JPI900. The engine numbers didn't move at all and every single number was in the green. the reminder of the climb out and flight was completely uneventful. I ran at 28-29/24 and 150 ROP.
WTF
I have had this happen one other time about 6 months ago I was in Cruse at 21K trailing about half cowl flaps At about an hour into a flight from boise to Missouri. again it lasted less that a second and not a peep from the engine monitor.
anybody ever had this happen ?
Thanks in advance
