Narrative:

My EMS helicopter as well as the helicopter were dispatched to the scene of an automatic over the side of a highway embankment. The helicopter landed first in a confined area next to the road in a town named xyz. The helicopter left the scene and upon leaving disturbed a large amount of debris. When my helicopter was landed in the same location shortly after the other helicopter, the debris was once again disturbed. This is not unusual in EMS helicopter operations, as we almost always are required to land adjacent to roadways where debris collects. After arrival at the hospital with our aircraft victim, a postflt was conducted and a 1 inch void in the main rotor blade tip cap was discovered. This void required temporarily grounding the helicopter and subsequent maintenance action. The blade sustained enough damage to require its removal and replacement.

Title: EMS OP FLC DISCOVERS ROTOR BLADE DAMAGE ON POSTFLT INSPECTION.

Narrative: MY EMS HELI AS WELL AS THE HELI WERE DISPATCHED TO THE SCENE OF AN AUTO OVER THE SIDE OF A HWY EMBANKMENT. THE HELI LANDED FIRST IN A CONFINED AREA NEXT TO THE ROAD IN A TOWN NAMED XYZ. THE HELI LEFT THE SCENE AND UPON LEAVING DISTURBED A LARGE AMOUNT OF DEBRIS. WHEN MY HELI WAS LANDED IN THE SAME LOCATION SHORTLY AFTER THE OTHER HELI, THE DEBRIS WAS ONCE AGAIN DISTURBED. THIS IS NOT UNUSUAL IN EMS HELI OPS, AS WE ALMOST ALWAYS ARE REQUIRED TO LAND ADJACENT TO ROADWAYS WHERE DEBRIS COLLECTS. AFTER ARR AT THE HOSPITAL WITH OUR ACFT VICTIM, A POSTFLT WAS CONDUCTED AND A 1 INCH VOID IN THE MAIN ROTOR BLADE TIP CAP WAS DISCOVERED. THIS VOID REQUIRED TEMPORARILY GNDING THE HELI AND SUBSEQUENT MAINT ACTION. THE BLADE SUSTAINED ENOUGH DAMAGE TO REQUIRE ITS REMOVAL AND REPLACEMENT.
