The Civil Aviation Safety Authority (CASA) issued Airworthiness Bulletin (AWB) 61-009 on 12 January 2012 to inform Australian operators of DHC-8 100-300 series aircraft about the design issue.
The AWB recommended an inspection of the power lever quadrant in order to ascertain the ongoing serviceability of the aircraft. Under Civil Aviation Regulations, CASA mandates all ADs from the State of Design. Accordingly, CF-2012-08 became a mandatory requirement for Australian operators on 30 January 2012.
The ATSB is satisfied with the manufacturers safety action concerning this safety issue.
