Bell 429 GlobalRanger, New York City Police Department, N917PD: Accident occurred September 01, 2016 - Rikers Island, New York

Aviation Accident Final Report - National Transportation Safety Board: https://app.ntsb.gov/pdf

NTSB Identification: ERA16CA313
14 CFR Public Aircraft
Accident occurred Thursday, September 01, 2016 in Rikers Island, NY
Probable Cause Approval Date: 05/15/2017
Aircraft: BELL HELICOPTER TEXTRON CANADA 429, registration: N917PD
Injuries: 6 Uninjured.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot was landing the helicopter on a nose-up slope when he "noticed the helicopter started to tilt aft." As the pilot "immediately" increased collective pitch and applied forward cyclic to abort the landing, three of the four main rotor blades struck the wire strike protection system on the cabin roof, which resulted in substantial damage to the blades. Representatives from the helicopter manufacturer examined the helicopter, replaced the three damaged rotor blades, and then returned the helicopter to service. According to the pilot, there were no mechanical deficiencies with the helicopter that would have prevented normal operation.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot’s overcontrolling of the helicopter during an aborted slope landing from a hover, which resulted in a main rotor blade strike.
