TRYING TO REPOSITION 206B ONTO TRAILER. SKID CAUGHT SIDE RAIL CAUSING DYNAMIC ROLLOVER. UNSUITIBLE LANDING AREA. (.19) ON APRIL 24, 1998, AT 1645 CENTRAL DAYLIGHT TIME, A BELL 206B HELICOPTER, N108RL, WAS SUBSTANTIALLY DAMAGED FOLLOWING A LOSS OF CONTROL WHILE LANDING NEAR JASPER, TEXAS. THE COMMERCIAL PILOT, SOLE OCCUPANT OF THE HELICOPTER, WAS NOT INJURED. VISUAL METEOROLOGICAL CONDITIONS PREVAILED FOR THE REPOSITIONING FLIGHT. THE HELICOPTER WAS OWNED BY ROTORCRAFT TECHNOLOGY INC., OF LAFAYETTE, LOUISIANA, AND WAS BEING OPERATED BY NORTH STAR HELICOPTERS INC., OF JASPER, TEXAS, UNDER TITLE 14 CFR PART 91. THE POSITIONING FLIGHT WAS ORIGINATING WHEN THE ACCIDENT OCCURRED. ACCORDING TO THE PILOT, THE HELICOPTER WAS DUE A 100-HOUR INSPECTION. THE HELICOPTER WAS SCHEDULED FOR ANOTHER AERIAL APPLICATION FLIGHT NEXT MORNING. THE PILOT ADDED THAT GROUND HANDLING WHEELS WERE NOT AVAILABLE TO GROUND HANDLE THE HELICOPTER INTO THE HANGAR FOR THE SCHEDULED MAINTENANCE. AS A LAST RESORT, THE MECHANIC ASKED THE PILOT TO REPOSITION THE HELICOPTER ON A UTILITY TRAILER EQUIPPED WITH 18 INCH SIDE RAILS, SO THE AIRCRAFT COULD BE MOVED INTO THE HANGAR TO PERFORM THE INSPECTION. THE PILOT STATED THAT AFTER ASSESSING THE SITUATION, HE AGREED TO REPOSITION THE HELICOPTER ONTO THE TRAILER. THE PILOT ADDED THAT WHILE REPOSITIONING THE HELICOPTER, THE TOE OF THE LEFT LANDING GEAR SKID WAS CAUGHT UNDER THE SIDE RAIL OF THE TRAILER. AS THE PILOT ATTEMPTED TO DISLODGE THE SKID FROM THE TRAILER, THE HELICOPTER ENCOUNTERED DYNAMIC ROLLOVER. AFTER THE MAIN ROTOR BLADES CONTACTED THE GROUND, THE HELICOPTER CAME TO REST ON ITS LEFT SIDE. EXAMINATION OF THE HELICOPTER BY THE FAA INSPECTOR CONFIRMED THAT THE MAIN ROTOR BLADES, THE MAIN ROTOR MAST AND LEFT HORIZONTAL STABILIZER SUSTAINED STRUCTURAL DAMAGE. ON THE RECOMMENDATION TO PREVENT SIMILAR ACCIDENT BLOCK OF THE PILOT/OPERATOR AIRCRAFT ACCIDENT REPORT (NTSB FORM 6120.1/2), THE PILOT STATED: "SHOULD NOT HAVE BEEN ATTEMPTED ON A TRAILER WITH HOLES IN THE SIDES FOR THE SKIDS TO BECOME LODGED." (.4) ACCORDING TO THE PILOT, A 100-HOUR INSPECTION OF THE HELICOPTER WAS DUE, AND GROUND HANDLING WHEELS WERE NOT AVAILABLE TO GROUND HANDLE THE HELICOPTER INTO THE HANGAR FOR THE SCHEDULED MAINTENANCE. THE MECHANIC ASKED THE PILOT TO REPOSITION THE HELICOPTER ON A UTILITY TRAILER, EQUIPPED WITH 18 INCH SIDE RAILS, SO THE HELICOPTER CO ULD BE TAKEN TO THE HANGAR. THE PILOT'S REASONING WAS INFLUENCED BY THE FACT THAT THE HELICOPTER WAS SCHEDULED FOR AN AERIAL APPLICATION FLIGHT THE NEXT MORNING. WHILE LANDING ON THE TRAILER, THE TOE OF THE LEFT SKID BECAME CAUGHT UNDER THE SIDE RAIL OF THE TRAILER, AND THE HELICOPTER ENCOUNTERED A DYNAMIC ROLLOVER. THE MAIN ROTOR BLADES CONTACTED THE GROUND, AND THE HELICOPTER CAME TO REST ON ITS LEFT SIDE. (-23) LEFT SKID HOOKED PORTION OF TRAILER, PILOT ATTEMPTED TO FREE AIRCRAFT. PILOT INDUCED DYNAMIC ROLLOVER. DAMAGED LEFT CHIN BUBBLE, DOOR, WINDOWN, ENGINE COWLING, STABILATOR, MAST, ROTOR BLADES, ENGINE AND TRANSMISSION DECK.

Probable cause: the pilot's encounter with a dynamic rollover after the toe of the left skid became caught on a trailer, while attempting to land the trailer. A related factor was: the pilot's perception of… From the FAA Accident/Incident Data System.
