Narrative:

We were only on duty for approximately two hours before the incident occurred; and were well rested. I do not believe that fatigue was a factor in this event. The flight segment start uneventfully. However; after departure; climbing through 17000 ft we received a left aft fuel pressure and right fwd fuel pressure warning. This is the first thing that grabbed our attention. Then; maybe five seconds after that we got an eqp oht indication; and followed by pitot static system faults (problem heat; captain pitot; left auxiliary pitot; and left aoa). The first officer was flying the aircraft and was instructed by me to continue to fly as I began to run the applicable checklists. Needless to say; things were deteriorating rapidly; which made checklist selection difficult. As I began to read the checklist we lost both eadi's and we had wxr fail warning on the ehsi. I selected the alternate efi; and it did not change the faulty display; so I subsequently deselected it. We then declared an emergency and requested vectors back to ZZZ for a visual approach. We were not able to determine what was the cause of our escalating problems; and were concerned as to what we were going to lose next. However; I knew we had two operational engines; and expeditiously turned the airplane around; ran all normal checklists; and landed. After touchdown the thrust reversers would not deploy. Fire crews were standing by; but we did not need further assistance. We taxied uneventfully to parking and shut down.callback conversation with reporter revealed the following information: the reporter has been in contact with his air carrier but the cause(south) of this failure have yet to be determined. The most puzzling aspect was the loss of both eadi's. A single power loss should never permit the loss of both flight instruments.

Title: A B757-200'S PITOT HEAT; WX RADAR; BOTH EADI'S; 2 FUEL PUMPS AND BOTH THRUST REVERSERS FAILED AFTER TKOF. AN EMER WAS DECLARED WITH RETURN TO LAND.

Narrative: WE WERE ONLY ON DUTY FOR APPROX TWO HOURS BEFORE THE INCIDENT OCCURRED; AND WERE WELL RESTED. I DO NOT BELIEVE THAT FATIGUE WAS A FACTOR IN THIS EVENT. THE FLT SEGMENT START UNEVENTFULLY. HOWEVER; AFTER DEP; CLBING THROUGH 17000 FT WE RECEIVED A L AFT FUEL PRESSURE AND R FWD FUEL PRESSURE WARNING. THIS IS THE FIRST THING THAT GRABBED OUR ATTENTION. THEN; MAYBE FIVE SECONDS AFTER THAT WE GOT AN EQP OHT INDICATION; AND FOLLOWED BY PITOT STATIC SYSTEM FAULTS (PROB HEAT; CAPT PITOT; L AUX PITOT; AND L AOA). THE FO WAS FLYING THE ACFT AND WAS INSTRUCTED BY ME TO CONTINUE TO FLY AS I BEGAN TO RUN THE APPLICABLE CHKLISTS. NEEDLESS TO SAY; THINGS WERE DETERIORATING RAPIDLY; WHICH MADE CHKLIST SELECTION DIFFICULT. AS I BEGAN TO READ THE CHKLIST WE LOST BOTH EADI'S AND WE HAD WXR FAIL WARNING ON THE EHSI. I SELECTED THE ALTERNATE EFI; AND IT DID NOT CHANGE THE FAULTY DISPLAY; SO I SUBSEQUENTLY DESELECTED IT. WE THEN DECLARED AN EMER AND REQUESTED VECTORS BACK TO ZZZ FOR A VISUAL APPROACH. WE WERE NOT ABLE TO DETERMINE WHAT WAS THE CAUSE OF OUR ESCALATING PROBLEMS; AND WERE CONCERNED AS TO WHAT WE WERE GOING TO LOSE NEXT. HOWEVER; I KNEW WE HAD TWO OPERATIONAL ENGINES; AND EXPEDITIOUSLY TURNED THE AIRPLANE AROUND; RAN ALL NORMAL CHKLISTS; AND LANDED. AFTER TOUCHDOWN THE THRUST REVERSERS WOULD NOT DEPLOY. FIRE CREWS WERE STANDING BY; BUT WE DID NOT NEED FURTHER ASSISTANCE. WE TAXIED UNEVENTFULLY TO PARKING AND SHUT DOWN.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR HAS BEEN IN CONTACT WITH HIS ACR BUT THE CAUSE(S) OF THIS FAILURE HAVE YET TO BE DETERMINED. THE MOST PUZZLING ASPECT WAS THE LOSS OF BOTH EADI'S. A SINGLE POWER LOSS SHOULD NEVER PERMIT THE LOSS OF BOTH FLT INSTRUMENTS.
