Early in December, Eurocopter and the EASA published an additional emergency service bulletin and accompanying emergency AD. All AS350/AS355 Ecureuil (AStar and TwinStar) models are affected. Although no evidence of laminated half-bearing deterioration has been found on pre-B3e models, inspections are mandated. However, as the inspection interval is 10 hours, the AD will probably cause less inconvenience than those affecting the B3e.
