N172SC
CESSNA 172N
WHILE THE PLT WAS PATROLLING A 115 KV POWER LINE, THE ACFT FLEW INTO A 230 KV LINE THAT CROSSED OVER THE 115 KV LINE. THE PLT FELT A 'JOLT' AS THE ACFT STRUCK THE 230 KV LINE, BUT THE ACFT CONTINUED FLYING. HE MADE A CONTROLLABILITY CHECK, THEN HE RETURNED TO THE ARPT & LANDED WITHOUT FURTHER INCIDENT. AN EXAM REVEALED DAMAGE TO THE LEFT WING TIP, VERTICAL STABILIZER & RUDDER.
INADEQUATE VISUAL LOOKOUT BY THE PILOT (FAILURE TO SEE & AVOID THE OBSTRUCTION). CONTRIBUTING FACTORS WERE THE TRANSMISSION (POWER) LINE AND LACK OF VISUAL CUES (PILOT'S VISUAL PERCEPTION).
