Drop In Manifold pressure
I was flying the 421c and at FL180 the left eng. drops to about 25MP while the right stays at 35MP. Up and until I hit FL180 all stays the same. I also have a pressurization problem that has started also. At FL220 cabin pressure was at 6000 now it is at 9000. Any Idea what this might be. Would it still be safe to fly to a repair station.
Thanks
