In October 2016, the Commission placed an item on its Watchlist titled Robinson helicopters: mast bumping accidents in New Zealand. The item was developed in response to a series of 14 accidents or incidents involving these helicopters (investigated either by the Commission or by the Civil Aviation Authority), including nine where low-G mast bumping is known to have occurred. The Commission sees good progress towards implementation of the actions we were seeking when we first placed this item on the Watchlist. The Commission is encouraged by the efforts taken by the sector since this safety issue has been placed on the Watchlist, particularly the manufacturer’s response to our recommendations, and its demonstrated commitment to safety. The sector must continue its efforts to reduce the risk of mast bumping accidents occurring.
