Narrative:

After takeoff, just as flaps were being retracted, strut overheat light for #1 engine illuminated. Followed operating manual procedures, to attempt to isolate problem. When attempting to restore throttle (it had been retarded to idle during procedure, and light had gone out), overheat light illuminated again. Returned to dca for uneventful landing. Callback conversation with reporter revealed the following information: the reporter stated the strut overheat light was on only at a high power setting and with the engine at idle the light was out. Reporter states that maintenance found a flexible pneumatic hose leaking where it rubbed against the stub wing structure.

WHEN ATTEMPTING TO RESTORE THROTTLE (IT HAD BEEN RETARDED TO IDLE DURING PROC, AND LIGHT HAD GONE OUT), OVERHEAT LIGHT ILLUMINATED AGAIN. RETURNED TO DCA FOR UNEVENTFUL LNDG. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE STRUT OVERHEAT LIGHT WAS ON ONLY AT A HIGH PWR SETTING AND WITH THE ENG AT IDLE THE LIGHT WAS OUT.
