BELL HELICOPTER TEXTRON CANADA 429
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.
