The clc of a B737-300 climb thrust after takeoff the right engine rolled back to idle thrust. This was caused by a broken compressor discharge line to main fuel control.

Narrative:
During acceleration after takeoff and just after flap retraction/climb thrust #2 engine rolled back to idle thrust and did not respond to throttle movement (throttle was still at climb setting). Completed appropriate checklists and returned to iad for overweight landing. Did not shut down engine in-flight and did not declare an emergency but did have fire trucks meet us to inspect brakes. Callback conversation with reporter revealed the following information: the reporter stated the cause of the right engine rollback from climb thrust to idle thrust was a broken compressor discharge line. The reporter said this line is an input to the main fuel control sensing.
Original NASA ASRS Text
Title: THE CLC OF A B737-300 CLB THRUST AFTER TAKEOFF THE R ENG ROLLED BACK TO IDLE THRUST. THIS WAS CAUSED BY A BROKEN COMPRESSOR DISCHARGE LINE TO MAIN FUEL CTL.
Narrative: DURING ACCELERATION AFTER TKOF AND JUST AFTER FLAP RETRACTION/CLB THRUST #2 ENG ROLLED BACK TO IDLE THRUST AND DID NOT RESPOND TO THROTTLE MOVEMENT (THROTTLE WAS STILL AT CLB SETTING). COMPLETED APPROPRIATE CHKLISTS AND RETURNED TO IAD FOR OVERWT LNDG. DID NOT SHUT DOWN ENG INFLT AND DID NOT DECLARE AN EMER BUT DID HAVE FIRE TRUCKS MEET US TO INSPECT BRAKES. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE CAUSE OF THE R ENG ROLLBACK FROM CLB THRUST TO IDLE THRUST WAS A BROKEN COMPRESSOR DISCHARGE LINE. THE RPTR SAID THIS LINE IS AN INPUT TO THE MAIN FUEL CTL SENSING.
