Unsafe condition
(1) Within 110 hours time-in-service (TIS) or before the MRH assembly accumulates 1,320 hours TIS, whichever occurs later, and thereafter at intervals not to exceed 1,320 hours TIS, visually inspect the rotating and stationary swashplates for corrosion or a crack by following the Accomplishment Instructions, paragraph 3.B.2 and Figures 1 through 3, of Eurocopter Alert Service Bulletin No. EC225-05A030, Revision 0, dated July 12, 2012 (ASB).

(ii) Within 150 hours TIS or 6 months after the inspection when the corrosion was first detected, whichever occurs first, replace the MRH assembly with an airworthy assembly.
