Kenneth Romm arrived to do IFR check. Found that connector at transponder antenna faulty; able to make a connection and complete transponder check but connecter will have to be replaced. See paper logbook sticker for transponder and encoder system check entry. Next, the pitot/static system was checked for leaks and none found. Took static from -1000' to 18000' and recorded values from the BMA sensor. Loaded the values into the altitude system calibration page and performed the altimeter check. See paper logbook sticker for altimeter check entry. Performed a quick check of the airspeed indicators; they read equal but lower than Kenneth's standard by about 4 knots.
