US NTSB investigators will assist with inquiry into deadly Singapore Airlines turbulence event

The US National Transportation Safety Board (NTSB) is sending representatives to assist Singapore’s investigation into the 21 May turbulence event that killed one passenger aboard a Singapore Airlines Boeing 777. The NTSB, which has long called for measures to address risks posed by turbulence, says its assistance aligns with ICAO-set investigation guidelines, which call for involvement by representatives from the state where an aircraft was manufactured. The US accident investigatory agency “is sending an accredited representative and four technical advisers to support the Singapore” investigation into the events involving Singapore Airlines Flight 321, the NTSB tweeted on 21 May. The Singapore Transport Safety Investigation Bureau is leading the inquiry. <br/>
