Narrative:
Crashed at sea while on charter to Agip.

According to one source (an AIBN report): The helicopter was in the enroute phase when the emergency floats inflated unintentionally. The helicopter began to rotate around the rotor mast during the subsequent landing. Finding of fatigue fracture in tail rotor blade no. 35317. The blade fracture was not related directly to the problems with the emergency floats. Alert Service Bulletin No. 05.00.17 issued by Eurocopter on 16 April 2003 introduced operating time limits and more intensive maintenance. This was later followed up by DGAC Airworthiness Directive No. T2003-155 dated 30 April 2003.
