Narrative:

3/91, after performing leak checks and releasing the aircraft back to an airworthy condition, I had a return back to fat due to high fuel flow and low egt on the left engine after climbing through 3000' AGL. The problem was found to be 2 fuel nozzles leaking. When I had done the leak checks for the fuel nozzles that were changed on the left engine, I did not see any fuel leaks coming from the nozzles or manifolds. Due to the raining WX that day, I did take extra time to examine each nozzle and manifold for leaks and none were noted. After the leak checks were done, both left and right engines were run at maximum power and maximum torque. All engine parameters were found to be normal.

Title: COMMUTER LTT AIR TURN BACK BECAUSE OF HIGH FUEL FLOW LOW TORQUE.

Narrative: 3/91, AFTER PERFORMING LEAK CHKS AND RELEASING THE ACFT BACK TO AN AIRWORTHY CONDITION, I HAD A RETURN BACK TO FAT DUE TO HIGH FUEL FLOW AND LOW EGT ON THE LEFT ENG AFTER CLBING THROUGH 3000' AGL. THE PROB WAS FOUND TO BE 2 FUEL NOZZLES LEAKING. WHEN I HAD DONE THE LEAK CHKS FOR THE FUEL NOZZLES THAT WERE CHANGED ON THE LEFT ENG, I DID NOT SEE ANY FUEL LEAKS COMING FROM THE NOZZLES OR MANIFOLDS. DUE TO THE RAINING WX THAT DAY, I DID TAKE EXTRA TIME TO EXAMINE EACH NOZZLE AND MANIFOLD FOR LEAKS AND NONE WERE NOTED. AFTER THE LEAK CHKS WERE DONE, BOTH LEFT AND RIGHT ENGS WERE RUN AT MAX PWR AND MAX TORQUE. ALL ENG PARAMETERS WERE FOUND TO BE NORMAL.
