Narrative:

I was returning to my home base at the jnu airport, ak, from a round-trip flight to gustauus, ak. I was cleared to land by the jnu ATC on runway 26. I was advised that another aircraft would be taking off prior to my landing and I saw it departing runway 26 as I was on my base leg. I was also aware of another aircraft cleared to land #2 behind me and observed it to be slowly overtaking me, but on the downwind leg. Additionally, I observed 2 air carrier B737's taxiing wbound for takeoff on the opposite direction (runway 8). As I believed my aircraft to be the slowest aircraft in the pattern and with the 2 B737's awaiting takeoff clearance on the opposite runway, I decided to make a shorter and quicker approach to help alleviate the congestion. As I turned final for runway 26, I rechked with the tower that I was cleared to land. The tower operator hesitated briefly, then reconfirmed I was cleared to land. I glanced at the VASI to determine my position and cut power and I had to land. As I touched down, I thought to myself that there must have been some wind, as the runway had partial snow cover and appeared narrower than usual, but was no problem for my aircraft and skill level. At this time, I congratulated myself for a 'perfect landing' (squeaked it on) and as the airplane weight settled (at 38 mph) I immediately realized I had landed on the taxiway to runway 26 and not the runway. I consciously decided that I should not apply power and go around due to the aircraft landing behind me and to my left. I saw the 2 B737 jets taxiing in the same direction, going away from me, toward the end of runway 8, the closest being 5000-6000 ft away from me. I determined the safest thing to do was to continue my taxi and exit the taxiway as quickly as possible. As I began to contact the tower, it called me. I responded to their call immediately with 'aircraft X, I just realized what I did.' I agreed to call them immediately upon reaching my tiedown. I explained that I immediately recognized my error, apologized profusely, and told the operator that I'd been flying in alaska for 40 yrs and couldn't believe I'd done what I did! I assured them it was a lesson learned and wouldn't be repeated. In hindsight, I believe my action was caused by momentary inattn to the runway and attempting to hurry my landing to help speed up other airport traffic. I also believe attempting a go around would have put me in close proximity with the aircraft landing behind me. In the future, my full attention will remain on the runway only.

Title: A PA12 PLT INADVERTENTLY LANDS ON A TXWY AT JNU BEHIND TAXIING B737.

Narrative: I WAS RETURNING TO MY HOME BASE AT THE JNU ARPT, AK, FROM A ROUND-TRIP FLT TO GUSTAUUS, AK. I WAS CLRED TO LAND BY THE JNU ATC ON RWY 26. I WAS ADVISED THAT ANOTHER ACFT WOULD BE TAKING OFF PRIOR TO MY LNDG AND I SAW IT DEPARTING RWY 26 AS I WAS ON MY BASE LEG. I WAS ALSO AWARE OF ANOTHER ACFT CLRED TO LAND #2 BEHIND ME AND OBSERVED IT TO BE SLOWLY OVERTAKING ME, BUT ON THE DOWNWIND LEG. ADDITIONALLY, I OBSERVED 2 ACR B737'S TAXIING WBOUND FOR TKOF ON THE OPPOSITE DIRECTION (RWY 8). AS I BELIEVED MY ACFT TO BE THE SLOWEST ACFT IN THE PATTERN AND WITH THE 2 B737'S AWAITING TKOF CLRNC ON THE OPPOSITE RWY, I DECIDED TO MAKE A SHORTER AND QUICKER APCH TO HELP ALLEVIATE THE CONGESTION. AS I TURNED FINAL FOR RWY 26, I RECHKED WITH THE TWR THAT I WAS CLRED TO LAND. THE TWR OPERATOR HESITATED BRIEFLY, THEN RECONFIRMED I WAS CLRED TO LAND. I GLANCED AT THE VASI TO DETERMINE MY POS AND CUT PWR AND I HAD TO LAND. AS I TOUCHED DOWN, I THOUGHT TO MYSELF THAT THERE MUST HAVE BEEN SOME WIND, AS THE RWY HAD PARTIAL SNOW COVER AND APPEARED NARROWER THAN USUAL, BUT WAS NO PROB FOR MY ACFT AND SKILL LEVEL. AT THIS TIME, I CONGRATULATED MYSELF FOR A 'PERFECT LNDG' (SQUEAKED IT ON) AND AS THE AIRPLANE WT SETTLED (AT 38 MPH) I IMMEDIATELY REALIZED I HAD LANDED ON THE TXWY TO RWY 26 AND NOT THE RWY. I CONSCIOUSLY DECIDED THAT I SHOULD NOT APPLY PWR AND GO AROUND DUE TO THE ACFT LNDG BEHIND ME AND TO MY L. I SAW THE 2 B737 JETS TAXIING IN THE SAME DIRECTION, GOING AWAY FROM ME, TOWARD THE END OF RWY 8, THE CLOSEST BEING 5000-6000 FT AWAY FROM ME. I DETERMINED THE SAFEST THING TO DO WAS TO CONTINUE MY TAXI AND EXIT THE TXWY AS QUICKLY AS POSSIBLE. AS I BEGAN TO CONTACT THE TWR, IT CALLED ME. I RESPONDED TO THEIR CALL IMMEDIATELY WITH 'ACFT X, I JUST REALIZED WHAT I DID.' I AGREED TO CALL THEM IMMEDIATELY UPON REACHING MY TIEDOWN. I EXPLAINED THAT I IMMEDIATELY RECOGNIZED MY ERROR, APOLOGIZED PROFUSELY, AND TOLD THE OPERATOR THAT I'D BEEN FLYING IN ALASKA FOR 40 YRS AND COULDN'T BELIEVE I'D DONE WHAT I DID! I ASSURED THEM IT WAS A LESSON LEARNED AND WOULDN'T BE REPEATED. IN HINDSIGHT, I BELIEVE MY ACTION WAS CAUSED BY MOMENTARY INATTN TO THE RWY AND ATTEMPTING TO HURRY MY LNDG TO HELP SPD UP OTHER ARPT TFC. I ALSO BELIEVE ATTEMPTING A GAR WOULD HAVE PUT ME IN CLOSE PROX WITH THE ACFT LNDG BEHIND ME. IN THE FUTURE, MY FULL ATTN WILL REMAIN ON THE RWY ONLY.
