## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

ON JULY 25, 2016, APPROXIMATELY 1050 LOCAL TIME, A TEXAS HELICOPTER CORP OH-13H/M74A, N10009, WAS

SUBSTANTIALLY DAMAGED DURING LOADING OPERATIONS NEAR MINONK, ILLINOIS. THE PILOT WAS NOT INJURED. THE

HELICOPTER WAS REGISTERED TO AND OPERATED BY HENDRICKSON FLYING SERVICE

THE APPLICATION NURSE TRUCK WAS STATIONARY AND PARKED ON THE RIGHT SHOULDER OF A PAVED RURAL COUNTY ROAD HEADED WESTBOUND AND WAS COMPLETELY CLEAR OF THE ROADWAY SURFACE. THE HELICOPTER WAS PARKED ON THE ELEVATED HELIPAD ON TOP OF THE NURSE TRUCK WITH THE HELICOPTER'S ENGINE OPERATING AND THE ROTOR BLADES TURNING. THE NOSE OF THE HELICOPTER WAS ORIENTED TO THE NORTH, AND THE HELICOPTER'S TAIL BOOM

AND THE ROTOR DISK THEN EXTENDED OVER THE NORTH EDGE OF THE PAVED ROAD.

NEAR THE END OF THE LOADING PROCESS, A WESTBOUND 18-WHEEL TRUCK DROVE UNDERNEATH THE HELICOPTER AND IMPACTED THE HELICOPTER'S TAIL BOOM. THE IMPACT RESULTED IN THE COMPLETE SEPARATION OF THE AFT HALF OF THE TAIL BOOM AND DISLODGED THE HELICOPTER FROM ITS POSITION ON THE NURSE TRUCK. THE HELICOPTER REMAINED UPRIGHT AND REMAINED ON THE TOP OF THE HELIPAD ONLY TURNING APPROXIMATELY 20 DEGREES. THE DRIVER OF THE 18-WHEELER TRUCK WAS NOT INJURED, BUT THE RIGHT EXHAUST STACK AND THE TOP LEFT EDGE OF THE TRAILER SHOWED DAMAGE WHICH CORRESPONDED TO THE IMPACT WITH THE HELICOPTER'S TAIL BOOM.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

Probable cause: Failure of the truck driver to ensure that he had adequate clearance to pass under the helicopter and the failure of the loader to park in a safer area for reloading operations.
