A captain and maintenance technician report about extensive corrosion damage found in the aft cargo compartment; aft equipment bay of a B757-200 aircraft. Pilot also notes immediate inspections and maintenance need to be accomplished on B757/767 aft fuselage sections to prevent a hull lost from similar excessive corrosion.

Narrative:
I was reassigned to fly a ferry flight for what I thought was to move a flight into position for a revenue trip. Instead it was a maintenance reposition; one time ferry flight; for a fuselage repair. This aircraft had extensive corrosion damage in the aft baggage [cargo] compartment that was discovered on a filter replacement the day before. The extensive damage had been there for quite some time.the photos shown to me by company air carrier maintenance technician; were eye opening. There was extensive damage to the stringers; and there was a wire bundle that could be seen hanging loose; no longer secured in place. When I asked the technician about the damage; he said he had seen worse. The photo looked like something you would see on a visit to the titanic. For the safety of crews and passengers alike; I feel that an inspection on all boeing B757/767 needs to be accomplished before a hull lost happens due to improper inspection/maintenance. This problem can have the same consequences as the md-80 jack-screw problem. We need to get these aircraft inspected and repaired system wide immediately.
