## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Airframe/component/system failure/malfunction, approach - faf/outer marker to threshold (ifr)
  - fire warning system,powerplant - false indication (cause)
- Miscellaneous/other, standing

## Analysis

THE BOEING 727 200 WAS ON FINAL APPROACH IN THE VICINITY OF THE OUTER MARKER WHEN AN INTERMITTENT FIRE WARNING INDICATION ON THE NUMBER ONE ENGINE STARTED.  THE ENGINE WAS SHUT DOWN AND THE FIRE BOTTLE WAS DISCHARGED; HOWEVER, THE FIRE WARNING CONTINUED.  WHEN THE AIRPLANE LANDED AND CLEARED THE RUNWAY IT WAS STOPPED.  THE FIRE WARNING CONTINUED AND A SECOND BOTTLE WAS DISCHARGED.  WHEN THE FIRE WARNING CONTINUED, A PRECAUTIONARY EMERGENCY EVACUATION WAS INITIATED.  POST INCIDENT EXAMINATION OF THE AIRPLANE DISCLOSED A CHAFFING FIRE LOOP ON THE NUMBER ONE ENGINE.
