Narrative:

Following a VOR approach into VFR conditions at sky, upon landing the aircraft impacted the ground about 50-60' short of runway threshold. The right maintenance tire struck some rocks and was destroyed. Following initial T/D upon the rocks. The aircraft skipped (bounced) once and rolled out on the runway with no further difficulty. Taxi to ramp was uneventful where the damaged tire was discovered. The runway surface was covered by patchy snow and ice and was adequate length for landing. However, due to runway conditions, I elected to land as close to the end of the runway as possible, and quite frankly, I misjudged my position in relation to the end of the runway and landed short. Visibility cues were somewhat scanty and misleading for landing: a completely snow-covered lake surface surrounding the runway, with an upslope from a snow-covered lake surface to the runway threshold which was visually disorienting; a small ridge of snow which obscured the runway edge and end lights, especially the green threshold lights; an inoperative runway REIL light (left side); and the rocks short of the runway threshold which were covered by snow and invisible from the air. The total effect of a 'whiteout' conditions with no solid cues for determining altitude on approach (VASI, G/south, etc) lent somewhat to the problems on approach, especially the snow covered lake surface which was totally obscured and gave the illusion of a totally flat surface leading to the end of the runway. Finally, the PF needs to pay closer attention to altitude in relation to the point of intended landing and adjust the rate of descent accordingly.

Title: LANDED SHORT TIRE BLOWN.

Narrative: FOLLOWING A VOR APCH INTO VFR CONDITIONS AT SKY, UPON LNDG THE ACFT IMPACTED THE GND ABOUT 50-60' SHORT OF RWY THRESHOLD. THE RIGHT MAINT TIRE STRUCK SOME ROCKS AND WAS DESTROYED. FOLLOWING INITIAL T/D UPON THE ROCKS. THE ACFT SKIPPED (BOUNCED) ONCE AND ROLLED OUT ON THE RWY WITH NO FURTHER DIFFICULTY. TAXI TO RAMP WAS UNEVENTFUL WHERE THE DAMAGED TIRE WAS DISCOVERED. THE RWY SURFACE WAS COVERED BY PATCHY SNOW AND ICE AND WAS ADEQUATE LENGTH FOR LNDG. HOWEVER, DUE TO RWY CONDITIONS, I ELECTED TO LAND AS CLOSE TO THE END OF THE RWY AS POSSIBLE, AND QUITE FRANKLY, I MISJUDGED MY POS IN RELATION TO THE END OF THE RWY AND LANDED SHORT. VIS CUES WERE SOMEWHAT SCANTY AND MISLEADING FOR LNDG: A COMPLETELY SNOW-COVERED LAKE SURFACE SURROUNDING THE RWY, WITH AN UPSLOPE FROM A SNOW-COVERED LAKE SURFACE TO THE RWY THRESHOLD WHICH WAS VISUALLY DISORIENTING; A SMALL RIDGE OF SNOW WHICH OBSCURED THE RWY EDGE AND END LIGHTS, ESPECIALLY THE GREEN THRESHOLD LIGHTS; AN INOP RWY REIL LIGHT (LEFT SIDE); AND THE ROCKS SHORT OF THE RWY THRESHOLD WHICH WERE COVERED BY SNOW AND INVISIBLE FROM THE AIR. THE TOTAL EFFECT OF A 'WHITEOUT' CONDITIONS WITH NO SOLID CUES FOR DETERMINING ALT ON APCH (VASI, G/S, ETC) LENT SOMEWHAT TO THE PROBS ON APCH, ESPECIALLY THE SNOW COVERED LAKE SURFACE WHICH WAS TOTALLY OBSCURED AND GAVE THE ILLUSION OF A TOTALLY FLAT SURFACE LEADING TO THE END OF THE RWY. FINALLY, THE PF NEEDS TO PAY CLOSER ATTN TO ALT IN RELATION TO THE POINT OF INTENDED LNDG AND ADJUST THE RATE OF DSCNT ACCORDINGLY.
