So where dose this end. What about fuel pumps, vac pumps etc etc. the manufacturer places this o/h limits for a reason. Weather you expect that or not that's the case. If you wish to have reliability in your aircraft and don't go on about how someone changed something and now it don't work. Point is the system has changed in regard to maintenance and you all have to except that or get your own som approved and try and convince someone to sign off on it with nil data against what the manufacturer has said. But don't blame the maintenance org for having to enforce something they don't have any option to do and weather or not we have an opinion on it. Because we relize what's good and what's not but we can't change it. And when an AWI grounds an aircraft because one decal is missing on an door well what do you won't me to say.
