A B737-400 WITH A RPTED ENG HOT START WAS CHKED PER MAINT MANUAL PROC AND CLRED. TECHNICIANS FAILED TO NOTE OF FURTHER CHKS REQUIRED.

Narrative

WHILE TROUBLESHOOTING A RPTED HOT START ON SAID ACR X; WE FOUND NO APPARENT MECHANICAL CAUSE FOR THE HOT START. MY LEAD DID SOME RESEARCH IN THE ACR X MANUAL. WE WORKED FROM MAINT MANUAL 71-00-41 WHICH REFERS YOU TO 71-00-41 PAGE 123. MY LEAD AND MYSELF READ THE NOTE ON THAT PAGE WHICH IN A NUT SHELL TELLS YOU IF YOU FOUND THE REASON FOR THE HOT START; NO FURTHER TROUBLESHOOTING IS NECESSARY. WE FIGURED THAT A HOT START FOR 1 DEG OVER FOR ONLY 1 SECOND COULD VERY WELL HAVE BEEN CAUSED FROM START LEVER MOVEMENT BEFORE 20% N2 AS DESCRIBED IN THE NOTE. AS CONTAINED IN THE LOGBOOK SIGNOFF WE CHKED MAX MOTORING ON THE #1 MOTOR AT 23% N2 TO WITHIN LIMITS. WE CHKED FOR PNEUMATIC LEAKS TO THE #1 STARTER AND ACCOMPLISHED APU FUNCTIONAL CHK TO VERIFY PROPER PRESSURE TO THE #1 MOTOR. I FAILED TO NOTICE THAT WHILE THIS NOTE STATES THAT NO FURTHER TROUBLESHOOTING IS NECESSARY IT REFERS YOU TO MAINT MANUAL 72-00-00/601 ENG OPS ABOVE LIMITS AND HIGH ENG STRESS INSPECTION FOR HOT START OF AN ENG. IT REFERS YOU TO MAINT MANUAL 72-00-00 PAGE 682. FOLLOWING THIS REF TAKES YOU RIGHT BACK TO MAINT MANUAL 71-00-41/101 WHICH REFERS YOU TO THE ORIGINAL MAINT MANUAL PAGE 71-00-41 PAGE 123 WHICH CONTAINS THE NOTE STATED ABOVE. I NOW KNOW THAT REGARDLESS OF WHAT THIS NOTE SAYS; YOU WILL HAVE FURTHER TROUBLESHOOTING AND INSPECTIONS ON ANY EGT EXCEEDANCE OVER 725 DEGS ON A B737-400.
