Narrative:

First flight for aircraft after completion of 'C' check. After takeoff left gear door unsafe light remained illuminated. At 3000 ft AGL and request for 'climb power' left engine did not respond to throttle movement. Engine indications remained at 1.7 EPR, 82% N1. Additional throttle movement jammed throttle at mid-throttle range, engine remained at 1.7 EPR and 82% N1. Aircraft climbed to 10000 ft (departure clearance), emergency declared in preparation for single engine landing, crash fire rescue equipment requested. Landing gear lowered to ascertain landing gear situation (3 safe gear achieved) and to provide drag for descent. Left engine secured, straight-in approach and landing approved. Remainder of single engine approach and landing normal. Callback conversation with reporter revealed the following information: the reporter said the aircraft was a DC9-30 and the engines were P&west JT8D-9 type. The reporter stated the throttle had movement initially but then failed at mid-throttle range when climb power was needed. The reporter said the cause was the throttle mechanism connection to the fuel control throttle input lever had become disconnected due to failure to properly safety the fuel control throttle lever bolt.

Original NASA ASRS Text

Title: A DC9-30 ON INITIAL CLB AT 3000 FT DECLARED AN EMER AND DIVERTED DUE TO INABILITY TO CTL #1 ENG PWR CAUSED BY AN IMPROPER THROTTLE TO FUEL CTL CONNECTION.

Narrative: FIRST FLT FOR ACFT AFTER COMPLETION OF 'C' CHK. AFTER TKOF L GEAR DOOR UNSAFE LIGHT REMAINED ILLUMINATED. AT 3000 FT AGL AND REQUEST FOR 'CLB PWR' L ENG DID NOT RESPOND TO THROTTLE MOVEMENT. ENG INDICATIONS REMAINED AT 1.7 EPR, 82% N1. ADDITIONAL THROTTLE MOVEMENT JAMMED THROTTLE AT MID-THROTTLE RANGE, ENG REMAINED AT 1.7 EPR AND 82% N1. ACFT CLBED TO 10000 FT (DEP CLRNC), EMER DECLARED IN PREPARATION FOR SINGLE ENG LNDG, CFR REQUESTED. LNDG GEAR LOWERED TO ASCERTAIN LNDG GEAR SIT (3 SAFE GEAR ACHIEVED) AND TO PROVIDE DRAG FOR DSCNT. L ENG SECURED, STRAIGHT-IN APCH AND LNDG APPROVED. REMAINDER OF SINGLE ENG APCH AND LNDG NORMAL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR SAID THE ACFT WAS A DC9-30 AND THE ENGS WERE P&W JT8D-9 TYPE. THE RPTR STATED THE THROTTLE HAD MOVEMENT INITIALLY BUT THEN FAILED AT MID-THROTTLE RANGE WHEN CLB PWR WAS NEEDED. THE RPTR SAID THE CAUSE WAS THE THROTTLE MECHANISM CONNECTION TO THE FUEL CTL THROTTLE INPUT LEVER HAD BECOME DISCONNECTED DUE TO FAILURE TO PROPERLY SAFETY THE FUEL CTL THROTTLE LEVER BOLT.
