Narrative:

After landing, I was cleared to taxi to parking. The cargo ramp was fairly full, with no movement of aircraft, vehicles, or people. I observed an opening between 2 metroliners. As I turned from a southerly direction to westerly between the 2 metros, the ramp lighting (sodium) reduced visibility by glare. The rain on the windscreen, and glare from the light reflection of standing water on ramp, reduced the visibility further. After passing the wingtips of the other planes, there was a loud 'thud' and the aircraft began to shake. The aircraft was taxied so as to be clear of the taxiway, and shut down. Upon exiting the aircraft, it was observed that one of the 3 blades had not feathered, and the front of the aircraft was covered with a red substance. Further investigation revealed that the propeller had impacted orange cones left on the ramp area. The fact that cones had not been collected and the sodium lighting contributed with the rain to a bad collection of circumstances.

Title: A C208 PROP STRUCK A MARKER CONE ON A WET CONGESTED RAMP AREA AT NIGHT WITH SODIUM VAPOR OVERHEAD RAMP ILLUMINATION.

Narrative: AFTER LNDG, I WAS CLRED TO TAXI TO PARKING. THE CARGO RAMP WAS FAIRLY FULL, WITH NO MOVEMENT OF ACFT, VEHICLES, OR PEOPLE. I OBSERVED AN OPENING BTWN 2 METROLINERS. AS I TURNED FROM A SOUTHERLY DIRECTION TO WESTERLY BTWN THE 2 METROS, THE RAMP LIGHTING (SODIUM) REDUCED VISIBILITY BY GLARE. THE RAIN ON THE WINDSCREEN, AND GLARE FROM THE LIGHT REFLECTION OF STANDING WATER ON RAMP, REDUCED THE VISIBILITY FURTHER. AFTER PASSING THE WINGTIPS OF THE OTHER PLANES, THERE WAS A LOUD 'THUD' AND THE ACFT BEGAN TO SHAKE. THE ACFT WAS TAXIED SO AS TO BE CLR OF THE TXWY, AND SHUT DOWN. UPON EXITING THE ACFT, IT WAS OBSERVED THAT ONE OF THE 3 BLADES HAD NOT FEATHERED, AND THE FRONT OF THE ACFT WAS COVERED WITH A RED SUBSTANCE. FURTHER INVESTIGATION REVEALED THAT THE PROP HAD IMPACTED ORANGE CONES LEFT ON THE RAMP AREA. THE FACT THAT CONES HAD NOT BEEN COLLECTED AND THE SODIUM LIGHTING CONTRIBUTED WITH THE RAIN TO A BAD COLLECTION OF CIRCUMSTANCES.
