I was ferrying an small aircraft from santa maria, ca, to clarksville, tn. On the way over the rocky mountains, I realized that the only way to keep performance of the airplane up was to fly as low as possible. Therefore, I decided to fly in 500' AGL over the interstate 40, which was the road I was following through the mountains. That decision was a bad one, especially over the mountain areas, and was made from lack of experience and bad preparation. As I was flying along, maintaining 500' AGL, just before the incident, I had my attention on my maps too long. When I looked up again, I realized that I was low (approximately 50' AGL). I pulled back on the stick, but too late to avoid the powerlines. The lines broke my windshield. In spite of this, I managed to land the airplane on the interstate with no further damage. I feel what happened was, where I landed on the continental divide, the terrain was rising on my route. And I, not having my attention where it should have been, did not notice my relative descent. I might even have been descending while looking at my maps. Not trying to excuse my own mistake.

Title: GA SMA HIT POWER LINES WHILE FOLLOWING THE INTERSTATE HIGHWAY THROUGH THE MOUNTAINS. ACFT DAMAGED EMERGENCY LNDG.
Narrative: I WAS FERRYING AN SMA FROM SANTA MARIA, CA, TO CLARKSVILLE, TN. ON THE WAY OVER THE ROCKY MOUNTAINS, I REALIZED THAT THE ONLY WAY TO KEEP PERFORMANCE OF THE AIRPLANE UP WAS TO FLY AS LOW AS POSSIBLE. THEREFORE, I DECIDED TO FLY IN 500' AGL OVER THE INTERSTATE 40, WHICH WAS THE ROAD I WAS FOLLOWING THROUGH THE MOUNTAINS. THAT DECISION WAS A BAD ONE, ESPECIALLY OVER THE MOUNTAIN AREAS, AND WAS MADE FROM LACK OF EXPERIENCE AND BAD PREPARATION. AS I WAS FLYING ALONG, MAINTAINING 500' AGL, JUST BEFORE THE INCIDENT, I HAD MY ATTN ON MY MAPS TOO LONG. WHEN I LOOKED UP AGAIN, I REALIZED THAT I WAS LOW (APPROX 50' AGL). I PULLED BACK ON THE STICK, BUT TOO LATE TO AVOID THE POWERLINES. THE LINES BROKE MY WINDSHIELD. IN SPITE OF THIS, I MANAGED TO LAND THE AIRPLANE ON THE INTERSTATE WITH NO FURTHER DAMAGE. I FEEL WHAT HAPPENED WAS, WHERE I LANDED ON THE CONTINENTAL DIVIDE, THE TERRAIN WAS RISING ON MY ROUTE. AND I, NOT HAVING MY ATTN WHERE IT SHOULD HAVE BEEN, DID NOT NOTICE MY RELATIVE DSCNT. I MIGHT EVEN HAVE BEEN DSNDING WHILE LOOKING AT MY MAPS. NOT TRYING TO EXCUSE MY OWN MISTAKE.
