What was found
UPON STARTER ENGAGEMENT FOR FIRST ENGINE START (EITHER ENGINE), THE NR 1 ENGINE FIRE ANNUNCIATOR WOULD ILLUMINATE ALONG WITH A FIRE TONE, BUT NO T-HANDLE ILLUMINATION. ILLUMINATION AND TONE WOULD CEASE AROUND 35-45% RPM. ALL FIRE DETECTION TESTS WOULD CHECK OK. REPLACEMENT OF NR 1 BOTTOM FLAME DETECTOR FIXED PROBLEM.
