Walrus;
1) That IS what I am concerned about.
2) The FAA AND manufacturers don't make recomendations, the manufacturers say hard time no extensions, zero full stop.
3) My last maintenance release notes the following;
Schedules/System of Maintenanceapplicable to this aircraft= CASA CAR 42B Maintenance schedule 5 (which is the system of maintenance for the aircraft periodical), and AD/ENG/4.9 Appendix "A" which is for the engine. I don't follow how CAR 42B takes precedence over AD/ENG/4.
Have I got that right?
