Narrative:

While on approach to runway 9 at private airport at winfield, ia, the aircraft I was flying hit and broke a power line which I didn't see until point of contact. Earlier in 6/90 another aircraft had crashed as a result of the same power line, at which time the orange marker balls and the power line the balls were attached to were pulled down to the ground upon impact, so there were no markers left visible for other approaching aircraft. When my aircraft came in contact with the power line I applied immediate go around procedures and aborted my landing. Upon landing the aircraft I immediately inspected for damage on the aircraft and found only paint scratches on the lower cowling at the point just in front of the nose wheel landing gear. The landing gear was not damaged. Further inspection found no damage to any other part of the aircraft, either. Burying the power line in the approach path area of the runway will prevent any recurrence in the future.

Title: SMA CONTACTS POWER LINE ON APCH TO PRIVATE ARPT.

Narrative: WHILE ON APCH TO RWY 9 AT PVT ARPT AT WINFIELD, IA, THE ACFT I WAS FLYING HIT AND BROKE A PWR LINE WHICH I DIDN'T SEE UNTIL POINT OF CONTACT. EARLIER IN 6/90 ANOTHER ACFT HAD CRASHED AS A RESULT OF THE SAME PWR LINE, AT WHICH TIME THE ORANGE MARKER BALLS AND THE PWR LINE THE BALLS WERE ATTACHED TO WERE PULLED DOWN TO THE GND UPON IMPACT, SO THERE WERE NO MARKERS LEFT VISIBLE FOR OTHER APCHING ACFT. WHEN MY ACFT CAME IN CONTACT WITH THE PWR LINE I APPLIED IMMEDIATE GAR PROCS AND ABORTED MY LNDG. UPON LNDG THE ACFT I IMMEDIATELY INSPECTED FOR DAMAGE ON THE ACFT AND FOUND ONLY PAINT SCRATCHES ON THE LOWER COWLING AT THE POINT JUST IN FRONT OF THE NOSE WHEEL LNDG GEAR. THE LNDG GEAR WAS NOT DAMAGED. FURTHER INSPECTION FOUND NO DAMAGE TO ANY OTHER PART OF THE ACFT, EITHER. BURYING THE PWR LINE IN THE APCH PATH AREA OF THE RWY WILL PREVENT ANY RECURRENCE IN THE FUTURE.
