 COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 107 CIVIL AVIATION SAFETY AUTHORITY
 SCHEDULE OF AIRWORTHINESS DIRECTIVES

           Compliance:  For propellers installed on aircraft certificated in the Agricultural or Acrobatic Category and which are known to have exceeded 400 hours total time in service - Unless previously carried out, within 100 hours time in service (TIS) from 30 March 1995. Thereafter, reinspect at intervals not exceeding 125 hours TIS.

           For propellers installed on an aircraft certificated in other than Agricultural or Acrobatic Category and which are known to have exceeded 700 hours total time in service - Unless previously carried out, within 100 hours time in service (TIS) from 30 March 1995. Thereafter, reinspect at intervals not exceeding 125 hours TIS.

           Background:  Recently there have been several cases where failure to detect a cracked hub has resulted in the loss of a propeller blade. This Directive was previously amended to require non dye oil filled propellers to be removed and inspected using red dye penetrant, and a warning to operators of potential pitch change problems if solvent is allowed to enter the blade socket area. This amendment is raised in sequence to require inspection for blade looseness, presence of expansion lock plugs and lubrication of the steel shim/circlip mounted in the blade retention nut.
