            Amendment 5 retains the inspection method and the repetitive inspection interval, but changes the initial inspection threshold. This change is in response to Transport Canada AD CF-1988-08 R1 which was prompted by three cases of cracks being found before the initial inspection threshold. The Authority has received several MDRs of cracked blade grips that were found before the initial 1200 hour inspection threshold.
