Some Entertainment Systems Wiring Problems
and Smoke/Fire Reports

 

50 Reports from 1988 to 2001.  Last revised 3/15/03  by jking1@attbi.com

 

Introduction

   

     The following is a chronological list and brief summaries to aircraft entertainment systems related events including significant systems failures, smoke and or fires.  This list is by no means intended to represent all such events known but rather is an attempt to focus more clearly on those available.  Those with the dates in Bold are where the entertainment systems were specifically identified.  Those without Bold draw attention to in flight fires where the entertainment systems may or may not have been the cause.  Of course all aircraft systems where designed and certified by the FAA and should not emit smoke or cause fires because proper circuit design expressly is supposed to stop this.  The purpose of circuit breakers is not to protect the equipment but rather to prevent electrical overloads and wire overheating.

 

     More critical to proper documentation of any such safety problems is the clear understating of  problems expressed through the most commonly used Databases made available to the public via the Internet.   Simply, these FAA Office Of System Safety Databases provided about 10 % of the events posted here compared to direct reports from pilots to the Aviation Safety Reporting  System (ASRS) or from maintenance in the Service Difficulty Reports (SDRs).  These  ratios can be seen as follows;

 

a.   The FAA Incident Data Reporting System  - 2 Events

b.   NTSB Monthly Reports  -  3 Events

c.   Aviation Safety Reporting System  (ASRS)  -  25 Events

d.  The Service Difficulty Reporting System (SDRs)  -  20 Events

e.  And miscellaneous FAA Tech Reports/Letters  -  3 Events

 

Some 10 Aviation Safety Reporting System Reports in their full text are given on pages 8 through 16.  The details offer a greater insight into the seriousness of these events.
