Analysis

The plt was transporting an external load of drywall panels when the acft's eng chip light illuminated. He set the load down & inspected the acft & eng. Finding nothing wrong, he reconnected the cable which was connected to the net containing the panels. However he inadvertently reconnected the cable to the acft in such a manner that it passed over the top of the right skid tube at the heel. During the subsequent lift-off the acft's nose abruptly pitched up & the acft rolled onto its right side impacting the terrain.
