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.
