Narrative:

I had spent the last 2 days in kingman, ar, training and taking my single engine commercial check ride. After a successful check ride, the WX in kingman deteriorated rapidly to IFR. After checking the WX, I filed an IFR flight plan to scottsdale. I did not think I was too tired to fly, however, until after takeoff. Upon takeoff, I was IMC immediately. The autoplt would not engage and I flew the route manually. The flight went without incident and I was passed off to scottsdale tower for a visual approach. I had already picked up the latest ATIS and knew the WX was VFR and they were using runway 21. Upon contacting the tower, I was cleared for the visual to runway 21 and told to proceed to the 'numbers.' there was 1 other plane entering downwind who had me insight. I was still looking for him. For some reason, I inverted the runway and entered a left downwind to runway 3. Just as I entered the downwind, I looked at the runway and saw the numbers. I realized my mistake. Just as I was calling the tower, the downwind traffic passed me on my right, same altitude, maybe 1000 ft from me. At that same time, the tower called and asked me what I was doing, and instructed me to turn left over the runway and enter a left downwind for runway 21. I was told I was to land behind a challenger. As I was starting to turn left base, the tower asked if I had the challenger in sight. I told them I had an aircraft on short final. This was not the challenger. It was just starting a long final 1/2 mi ahead of me. The tower told me to stop my base turn and follow the challenger, which I did. After reviewing the incident, I realize I was much too tired to fly. After not sleeping well the night before, an early morning training flight, followed by a check ride, then having to hand fly an IMC flight to scottsdale, it was easy to make a mistake. In the future, I will be rested enough to handle in-flight difficulties and still land safely.

Title: A C340 PLT EXPERIENCES 2 POTENTIAL TFC CONFLICTS WHEN HE FAILS TO FOLLOW THE 2 CLRNCS AS ISSUED FOR LNDG ON RWY 21 AT SDL, AZ.

Narrative: I HAD SPENT THE LAST 2 DAYS IN KINGMAN, AR, TRAINING AND TAKING MY SINGLE ENG COMMERCIAL CHK RIDE. AFTER A SUCCESSFUL CHK RIDE, THE WX IN KINGMAN DETERIORATED RAPIDLY TO IFR. AFTER CHKING THE WX, I FILED AN IFR FLT PLAN TO SCOTTSDALE. I DID NOT THINK I WAS TOO TIRED TO FLY, HOWEVER, UNTIL AFTER TKOF. UPON TKOF, I WAS IMC IMMEDIATELY. THE AUTOPLT WOULD NOT ENGAGE AND I FLEW THE RTE MANUALLY. THE FLT WENT WITHOUT INCIDENT AND I WAS PASSED OFF TO SCOTTSDALE TWR FOR A VISUAL APCH. I HAD ALREADY PICKED UP THE LATEST ATIS AND KNEW THE WX WAS VFR AND THEY WERE USING RWY 21. UPON CONTACTING THE TWR, I WAS CLRED FOR THE VISUAL TO RWY 21 AND TOLD TO PROCEED TO THE 'NUMBERS.' THERE WAS 1 OTHER PLANE ENTERING DOWNWIND WHO HAD ME INSIGHT. I WAS STILL LOOKING FOR HIM. FOR SOME REASON, I INVERTED THE RWY AND ENTERED A L DOWNWIND TO RWY 3. JUST AS I ENTERED THE DOWNWIND, I LOOKED AT THE RWY AND SAW THE NUMBERS. I REALIZED MY MISTAKE. JUST AS I WAS CALLING THE TWR, THE DOWNWIND TFC PASSED ME ON MY R, SAME ALT, MAYBE 1000 FT FROM ME. AT THAT SAME TIME, THE TWR CALLED AND ASKED ME WHAT I WAS DOING, AND INSTRUCTED ME TO TURN L OVER THE RWY AND ENTER A L DOWNWIND FOR RWY 21. I WAS TOLD I WAS TO LAND BEHIND A CHALLENGER. AS I WAS STARTING TO TURN L BASE, THE TWR ASKED IF I HAD THE CHALLENGER IN SIGHT. I TOLD THEM I HAD AN ACFT ON SHORT FINAL. THIS WAS NOT THE CHALLENGER. IT WAS JUST STARTING A LONG FINAL 1/2 MI AHEAD OF ME. THE TWR TOLD ME TO STOP MY BASE TURN AND FOLLOW THE CHALLENGER, WHICH I DID. AFTER REVIEWING THE INCIDENT, I REALIZE I WAS MUCH TOO TIRED TO FLY. AFTER NOT SLEEPING WELL THE NIGHT BEFORE, AN EARLY MORNING TRAINING FLT, FOLLOWED BY A CHK RIDE, THEN HAVING TO HAND FLY AN IMC FLT TO SCOTTSDALE, IT WAS EASY TO MAKE A MISTAKE. IN THE FUTURE, I WILL BE RESTED ENOUGH TO HANDLE INFLT DIFFICULTIES AND STILL LAND SAFELY.
