EASA 2019-0280

Requires a service life limit and repetitive inspections of the spherical thrust bearings. This action results from an investigation revealing that the Airworthiness Limitation Section of the model AS 350 BB did not include the life limit for the affected part, as well as a repetitive inspection task. This condition, if not corrected, could lead to extended in-service use and consequent failure of an affected part, possibly resulting in loss of control of the aircraft.
