Narrative

SEEKING TO OBTAIN MY COMPLEX RATING; I CALLED AND ARRANGED TO FLY WITH AN INSTRUCTOR. MY INSTRUCTOR ASKED IF I HAD ANY TIME IN A COMPLEX ACFT AND I STATED THAT I HAD A LITTLE OVER 1 HR APPROX 2 1/2 YRS AGO. I EXPLAINED THAT MY RECENT FLYING WAS IN A VERY BASIC EXPERIMENTAL TYPE TAIL DRAGGER THAT HAD NO ELECTRONICS; RADIOS; FLAPS; ETC. AFTER A SHORT EXPLANATION OF EQUIP; STARTUP; CHKLISTS; RUN-UPS; CLRNCS; ETC; WE WERE ABLE TO DEPART TO THE TRAINING AREA. AFTER ARRIVING THERE; THE INSTRUCTOR EXPLAINED THE GEAR LIGHTS; RAN THE GEAR UP AND DOWN BOTH BY GEAR LEVER AND MANUALLY. THERE WAS AN EXPLANATION OF PROP SETTING AND ONE SIMULATED EMER LNDG. THE INSTRUCTOR THEN ASKED ME WHAT I WANTED TO DO NEXT. I STATED THAT I 'DIDN'T KNOW; WHAT DO YOU THINK? YOU'RE THE INSTRUCTOR.' HE SAID WE SHOULD GO BACK TO THE ARPT FOR TOUCH-AND-GOES. HE FELT I WOULD GET THE HANG OF THE EQUIP QUICKER IF I WERE IN THE PATTERN. I SAID OK AND WE WENT BACK. THE FIRST 2 TOUCH-AND-GOES WERE OK. LNDGS WERE BUMPY. IN THE PATTERN; THE INSTRUCTOR WAS DOING THE RADIOS; FLAPS; AND ADVISING ME WHAT TO DO WITH THE PROP AND GEAR. DUE TO THE SHORT AMOUNT OF TIME I HAD WITH THIS EQUIP AND MY LACK OF KNOWLEDGE AS TO WHERE EVERYTHING WAS; AFTER WE WOULD TOUCH DOWN; THE INSTRUCTOR SET AND VERIFIED THE EQUIP LEAVING ME WITH THE CARB HEAT AND THROTTLE. AFTER THE SECOND LNDG; I WAS LOOKING OUT THE WINDOW AT THE CTRLINE; THE PLANE FELT NORMAL AND ACCELERATING. I THEN SAW THE NOSE DROP AND WE WERE SLIDING TO THE L. THE INSTRUCTOR TOLD ME TO PULL THE PWR BACK; WHICH I DID. TOTAL TIME OF LESSON WAS 0.7 HRS. WHEN THE INSTRUCTOR GOT OUT OF THE PLANE; HE STARTED TELLING EVERYONE I HAD PULLED THE GEAR INSTEAD OF GIVING FULL THROTTLE. I WAS BUSY HELPING TO PUSH THE PLANE OFF THE RWY WITH THE OTHER PEOPLE THAT HAD COME OUT TO HELP. I TOLD THE INSTRUCTOR THAT I DID NOT PULL THE GEAR. I DID NOT KNOW EXACTLY WHERE THE LEVER WAS TO BE FOUND IN THE PANEL. I WOULD HAVE TO HAVE LET GO OF THE THROTTLE; LOOK FOR THE GEAR LEVER; PULL IT OUT; AND LIFT UP. I WOULD HAVE REMEMBERED THAT.
