Narrative:

After a normal, full power, takeoff; upon setting climb thrust, I noticed what felt like a need for rudder trim. The climb out and acceleration was degraded for our weight. I then noticed the left engine EPR was not producing the thrust called for by the thrust bank. Tried in-flight initial, advancing throttle, and idle thrust. No help. (Flight manual procedure also no help). All parameters were normal and engine ran fine, but it would not produce climb power. Landed jfk as closest airport and let the engine run as it was ok at reduced power settings. Normal landing, but I called out emergency equipment just in case. Please note: the many procedures and radio contacts necessary to return to the airport when you have an engine problem degrade drastically from the operation. Most are unnecessary and add to the time required to get back on the ground. Probably the company required contacts through arinc are the worst offenders (dispatch, maintenance, etc) serving no useful safety of flight issue but distraction at the first officer, just when I need him, this is just the very time when you need a 2 man cockpit -- not a 1 man operation.

Title: DIVERSION TO ALTERNATE ARPT AFTER LGT HAS ACFT EQUIP PROBLEM OF REDUCED THRUST FROM ONE ENG. EMER DECLARED AND EMER GND EQUIP ASKED FOR.

Narrative: AFTER A NORMAL, FULL PWR, TKOF; UPON SETTING CLB THRUST, I NOTICED WHAT FELT LIKE A NEED FOR RUDDER TRIM. THE CLBOUT AND ACCELERATION WAS DEGRADED FOR OUR WT. I THEN NOTICED THE L ENG EPR WAS NOT PRODUCING THE THRUST CALLED FOR BY THE THRUST BANK. TRIED INFLT INITIAL, ADVANCING THROTTLE, AND IDLE THRUST. NO HELP. (FLT MANUAL PROC ALSO NO HELP). ALL PARAMETERS WERE NORMAL AND ENG RAN FINE, BUT IT WOULD NOT PRODUCE CLB PWR. LANDED JFK AS CLOSEST ARPT AND LET THE ENG RUN AS IT WAS OK AT REDUCED PWR SETTINGS. NORMAL LNDG, BUT I CALLED OUT EMER EQUIP JUST IN CASE. PLEASE NOTE: THE MANY PROCS AND RADIO CONTACTS NECESSARY TO RETURN TO THE ARPT WHEN YOU HAVE AN ENG PROBLEM DEGRADE DRASTICALLY FROM THE OP. MOST ARE UNNECESSARY AND ADD TO THE TIME REQUIRED TO GET BACK ON THE GND. PROBABLY THE COMPANY REQUIRED CONTACTS THROUGH ARINC ARE THE WORST OFFENDERS (DISPATCH, MAINT, ETC) SERVING NO USEFUL SAFETY OF FLT ISSUE BUT DISTR AT THE FO, JUST WHEN I NEED HIM, THIS IS JUST THE VERY TIME WHEN YOU NEED A 2 MAN COCKPIT -- NOT A 1 MAN OP.
