SMA ACFT TAXIING IN AREA OF CONSTRUCTION HIT POLE WITH WING.

Narrative

I WAS TAXIING W IN FRONT OF ROW TOWARD RUN-UP AREA. AFTER NOTICING SEVERAL OF THE AIRPLANES PARKED FORWARD OF THE TEE I WAS CONTINUING MY TAXI SLOWLY AND CAREFULLY JUST SLIGHTLY L OF THE YELLOW LINE WHILE CAREFULLY MONITORING MY R WINGTIP TO ENSURE ADEQUATE CLRNC. AT THE SAME TIME I WAS PLANNING TO MANEUVER AROUND AND BTWN THE 2 YELLOW PROTRUDING DRAIN COVERS AND POTHOLES AS I BEGAN MY TURN INTO THE RUN-UP AREA TO AVOID STRIKING THE PROP. THROUGH PREVIOUS EXPERIENCE THIS METHOD OF TAXIING HAS PROVEN TO BE A SAFE AND RELIABLE RTE TO RUN-UP AREA; BY AVOIDING CONTACT WITH PARKED AIRPLANES AND PREVENTING POSSIBLE PROP STRIKES WITH THE DRAIN COVERS OR POTHOLES. UNFORTUNATELY AFTER CHKING NOTAMS; ATIS AND ANY OTHER NOTIFICATION THERE WAS NO MENTION OF CONSTRUCTION WHICH HAD BEGUN SINCE MY PREVIOUS FLT. DURING THE TAXI THE L WINGTIP STRUCK A NEWLY PLACED CONSTRUCTION POLE IN AN AREA WHICH I HAD PREVIOUSLY KNOWN TO BE COMPLETELY CLR OF OBSTACLES. UPON REALIZING THAT THE ACFT STRUCK AN OBJECT I IMMEDIATELY SHUT DOWN THE ENG; INSPECTED THE ACFT AND BRIEFED THE OPS MGR ON WHAT HAD HAPPENED. I FEEL THAT ALL STUDENTS AND INSTRUCTORS SHOULD BE BRIEFED ON ANY CONSTRUCTION OR OTHER NEW HAZARDS IN OUR UNCTLED MOVEMENT AREA.
