My comment:

I am an 11,000 hour ATP rated pilot with commercial ASEL, rotorcraft, and glider privileges. I am also type rated in LR-Jet, D-328Jet, MiG-15 and MiG-17 aircraft. I feel that the requirement to undergo an annual proficiency check in a jet powered glider is unnecessary and creates an undo burden on the limited FAA resources. The difference in risk to the public between a normal glider and a turbine powered glider would be negligible. There is no speed difference between the two aircraft and the amount of fuel carried in a turbine powered glider is generally less than 20 gallons. This limited risk would not justify the high level of FAA surveillance through annual proficiency check.
