Narrative:

The traffic pattern was entered from the southwest. I entered the pattern observing a calm 3 or 4 KT wind from the northwest. I entered a left downwind for runway 34, all power settings were by the book, gear flaps, etc. The runway is 3600' long. When on final a slight 'thud' barely audible was heard. After a normal landing, I taxied to the ramp and shut down. As I walked to the front of the aircraft I noticed a power cable wrapped around the nosewheel. In talking to the power company people at philipsburg, he estimated the line to be 1/4 to 1/8 mi from end of runway. I was using a WAC chart and the montana aeronautical directory for airport layout. No power line was shown and no lights on power poles visible indicating obstruction on approach.

Title: ATX SMT HIT UNMARKED POWER LINE ON APCH TO U05.

Narrative: THE TFC PATTERN WAS ENTERED FROM THE SW. I ENTERED THE PATTERN OBSERVING A CALM 3 OR 4 KT WIND FROM THE NW. I ENTERED A LEFT DOWNWIND FOR RWY 34, ALL PWR SETTINGS WERE BY THE BOOK, GEAR FLAPS, ETC. THE RWY IS 3600' LONG. WHEN ON FINAL A SLIGHT 'THUD' BARELY AUDIBLE WAS HEARD. AFTER A NORMAL LNDG, I TAXIED TO THE RAMP AND SHUT DOWN. AS I WALKED TO THE FRONT OF THE ACFT I NOTICED A PWR CABLE WRAPPED AROUND THE NOSEWHEEL. IN TALKING TO THE PWR COMPANY PEOPLE AT PHILIPSBURG, HE ESTIMATED THE LINE TO BE 1/4 TO 1/8 MI FROM END OF RWY. I WAS USING A WAC CHART AND THE MONTANA AERONAUTICAL DIRECTORY FOR ARPT LAYOUT. NO PWR LINE WAS SHOWN AND NO LIGHTS ON PWR POLES VISIBLE INDICATING OBSTRUCTION ON APCH.
