NOTES

 

Weather

-        Elevated thunderstorms developed in the southern research area

-        These storms would develop, dissipate and a new storm would develop on the south/southeast flank

-        The initial target was a dying thunderstorm with bases at 12,000 MSL

o        It was outflow dominate with primarily ice particles and light turbulence

-        The second target was an actively developing thunderstorm that developed linearly to the east/northeast

o        This was a compact but vigorous storm with moderate turbulence and small hail

o        The aircraft accumulated approximately inch of ice in about 15 minutes

o        There were approximately 4 lightning flashes with one striking the aircraft on the propeller

 

Maintenance

-        Prior to this flight, the oil cooler flow through door was modified to full open

o        This allowed for the cowl flaps to be closed to control cylinder head temperature without affecting oil temperature

o        Oil temperature again ran approximately 90 C throughout the flight

o        Cylinder head temperature ran approximately 150 C even with the cowl flaps closed down

-        The GPS initially did not have power on startup

o        The anchor shaft that pulls the unit into the housing was not in the proper exit whole and therefore was not pulling the unit into the housing

o        Anchor shaft was repositioned and the unit worked normally

-        Evidence of the lightning strike was found on one of the propeller blades

o        A small metal burn with an associated metal pock mark was found on the edge of the propeller on the side opposite the direction of rotation

-        Need to increase the radio sidetone on radio 2

-        My helmet communication cords are failing

o        Flew with Tom Root's helmet and replace my helmet's comm cords with Tom Root's after the flight

 

Operations

-        Good coordination between Ops and Thor

-        Primarily lined up penetration runs visually with confirmation from Ops
