Narrative:

Due to several acquisitions and mergers, air carrier presently operates several configns of the B727. On the JT8 engine we presently have, there is the kidde and systron-donner fire detection loops. The kidde fire detection system was installed on the new engine and should have been xferred to the systron-donner system. The conversion was not fully completed due to confusion over the job instruction card. The confusion was a result of an overage of not applicable job instruction cards routinely issued as a result of several different engine configns and no indication or reference available on the job form as to the type of buildup confign on the new engine to be installed. Had there been some kind of simplification of engine system types or better clarification on the job instruction card, job form, or the preflight handbook, this could be avoided.

Title: A B727-200 WAS DISPATCHED IN NON COMPLIANCE WITH THE IMPROPER ENG FIRE WARNING SENSOR LOOP INSTALLED.

Narrative: DUE TO SEVERAL ACQUISITIONS AND MERGERS, ACR PRESENTLY OPERATES SEVERAL CONFIGNS OF THE B727. ON THE JT8 ENG WE PRESENTLY HAVE, THERE IS THE KIDDE AND SYSTRON-DONNER FIRE DETECTION LOOPS. THE KIDDE FIRE DETECTION SYS WAS INSTALLED ON THE NEW ENG AND SHOULD HAVE BEEN XFERRED TO THE SYSTRON-DONNER SYS. THE CONVERSION WAS NOT FULLY COMPLETED DUE TO CONFUSION OVER THE JOB INSTRUCTION CARD. THE CONFUSION WAS A RESULT OF AN OVERAGE OF NOT APPLICABLE JOB INSTRUCTION CARDS ROUTINELY ISSUED AS A RESULT OF SEVERAL DIFFERENT ENG CONFIGNS AND NO INDICATION OR REF AVAILABLE ON THE JOB FORM AS TO THE TYPE OF BUILDUP CONFIGN ON THE NEW ENG TO BE INSTALLED. HAD THERE BEEN SOME KIND OF SIMPLIFICATION OF ENG SYS TYPES OR BETTER CLARIFICATION ON THE JOB INSTRUCTION CARD, JOB FORM, OR THE PREFLT HANDBOOK, THIS COULD BE AVOIDED.
