Narrative:

While in an small aircraft approaching to land at hut airport, ks, after listening to an aircraft report entry into the air traffic area from the southwest, I reported I was entering from the northwest, when in fact I was entering from the northeast. Shortly after entering the air traffic area I reported my mistake. I then proceeded to enter a right hand downwind for runway 35. I was cleared to land. Abeam the end of runway 35 I turned on the carburetor heat, lowered my RPM's to 1700, and set flaps at 20 degrees. I seemed to have a hard time maintaining 70 KTS. As I turned right base I noticed both that I was a little far out for short final and that I must have inadvertently flipped the flap switch to up instead of neutral. I set the flaps to 30 degrees and was now having a hard time maintaining 65 KTS. When I turned final I realized I was somewhat low and I increased power. My descent was still too fast and again I increased power. I had a hard time just trying to maintain 60 KTS at nearly full power, and once saw the speed drop off to around 55 KTS. I thought vaguely about going around but I didn't want to retract my flaps because of my proximity to the ground and the aircraft's poor rate of climb. I barely made it over the fence obstruction near the end of the runway, but I made it to the end of the runway and entered ground effect which finally leveled off my descent. I then flared and landed normally. However, I think I must have landed before the displaced threshold line. I don't know for sure and the tower didn't say anything, but by their tone when informed to taxi to the ramp seemed to imply that they weren't very happy about what had just transpired. This flight was the conclusion of my second cross country that day, in which I had gone to top airport (billard airport) to a job interview. I had some lack of sleep from the previous night, and was tired, hungry, and a little motion sick when I landed. What's worse was that hut is my home airport, yet I had forgotten about the displaced threshold on runway 35 altogether through the whole landing phase, and it only occurred later to me on the drive home about the displaced threshold. Had I remembered that initially, the landing would have had a much greater safety factor. I can only attribute the incident to fatigue, lack of proficiency (I hadn't flown in 2 months prior for mostly monetary reasons), and low time in type. It was a hard learned lesson that I need to keep my proficiency up, I need to always keep ahead of the aircraft, and that I need to make sure that mentally and physically that I'm good to go.

Title: ERROR ADMITTED BY SMA PLT IN LNDG PROC UNDERSHOT.

Narrative: WHILE IN AN SMA APCHING TO LAND AT HUT ARPT, KS, AFTER LISTENING TO AN ACFT RPT ENTRY INTO THE ATA FROM THE SW, I RPTED I WAS ENTERING FROM THE NW, WHEN IN FACT I WAS ENTERING FROM THE NE. SHORTLY AFTER ENTERING THE ATA I RPTED MY MISTAKE. I THEN PROCEEDED TO ENTER A R HAND DOWNWIND FOR RWY 35. I WAS CLRED TO LAND. ABEAM THE END OF RWY 35 I TURNED ON THE CARB HEAT, LOWERED MY RPM'S TO 1700, AND SET FLAPS AT 20 DEGS. I SEEMED TO HAVE A HARD TIME MAINTAINING 70 KTS. AS I TURNED R BASE I NOTICED BOTH THAT I WAS A LITTLE FAR OUT FOR SHORT FINAL AND THAT I MUST HAVE INADVERTENTLY FLIPPED THE FLAP SWITCH TO UP INSTEAD OF NEUTRAL. I SET THE FLAPS TO 30 DEGS AND WAS NOW HAVING A HARD TIME MAINTAINING 65 KTS. WHEN I TURNED FINAL I REALIZED I WAS SOMEWHAT LOW AND I INCREASED PWR. MY DSCNT WAS STILL TOO FAST AND AGAIN I INCREASED PWR. I HAD A HARD TIME JUST TRYING TO MAINTAIN 60 KTS AT NEARLY FULL PWR, AND ONCE SAW THE SPD DROP OFF TO AROUND 55 KTS. I THOUGHT VAGUELY ABOUT GOING AROUND BUT I DIDN'T WANT TO RETRACT MY FLAPS BECAUSE OF MY PROX TO THE GND AND THE ACFT'S POOR RATE OF CLB. I BARELY MADE IT OVER THE FENCE OBSTRUCTION NEAR THE END OF THE RWY, BUT I MADE IT TO THE END OF THE RWY AND ENTERED GND EFFECT WHICH FINALLY LEVELED OFF MY DSCNT. I THEN FLARED AND LANDED NORMALLY. HOWEVER, I THINK I MUST HAVE LANDED BEFORE THE DISPLACED THRESHOLD LINE. I DON'T KNOW FOR SURE AND THE TWR DIDN'T SAY ANYTHING, BUT BY THEIR TONE WHEN INFORMED TO TAXI TO THE RAMP SEEMED TO IMPLY THAT THEY WEREN'T VERY HAPPY ABOUT WHAT HAD JUST TRANSPIRED. THIS FLT WAS THE CONCLUSION OF MY SECOND XCOUNTRY THAT DAY, IN WHICH I HAD GONE TO TOP ARPT (BILLARD ARPT) TO A JOB INTERVIEW. I HAD SOME LACK OF SLEEP FROM THE PREVIOUS NIGHT, AND WAS TIRED, HUNGRY, AND A LITTLE MOTION SICK WHEN I LANDED. WHAT'S WORSE WAS THAT HUT IS MY HOME ARPT, YET I HAD FORGOTTEN ABOUT THE DISPLACED THRESHOLD ON RWY 35 ALTOGETHER THROUGH THE WHOLE LNDG PHASE, AND IT ONLY OCCURRED LATER TO ME ON THE DRIVE HOME ABOUT THE DISPLACED THRESHOLD. HAD I REMEMBERED THAT INITIALLY, THE LNDG WOULD HAVE HAD A MUCH GREATER SAFETY FACTOR. I CAN ONLY ATTRIBUTE THE INCIDENT TO FATIGUE, LACK OF PROFICIENCY (I HADN'T FLOWN IN 2 MONTHS PRIOR FOR MOSTLY MONETARY REASONS), AND LOW TIME IN TYPE. IT WAS A HARD LEARNED LESSON THAT I NEED TO KEEP MY PROFICIENCY UP, I NEED TO ALWAYS KEEP AHEAD OF THE ACFT, AND THAT I NEED TO MAKE SURE THAT MENTALLY AND PHYSICALLY THAT I'M GOOD TO GO.
