IASA STUDY OF  270  WIRE-RELATED ACCIDENTS/INCIDENTS  

                             LAST REVISED. 3/2/2001 by jking1@mediaone.net.  IASA Data Specialist    

 

Introduction

   

     The following is a chronological list and brief summaries to aircraft “Wire” related events including significant systems failures, smoke and or fires.  Some industry actions have also been added.  This list is by no means intended to represent all such events known but rather is an attempt to focus more clearly on those where wire or wire types become known. Other IASA studies are available that broaden these number of events where “electrical” becomes the focus rather than just those where the word “wire” is more easily recognized.  109 additional such items to the 270 here may be found on page 14.

   

      Identifying the various wire types or that the wires themselves have become directly causal is difficult because of the absence of such fault coding in the ATA coding system used throughout the commercial industry.  The industry has now recognized this diminishing factor and recognized by the military some years ago.

Limitations    

 

     The aircraft events listed here are limited to the larger types of commercial transports, all reports to the commuter-type craft (i.e. Beech, Saab, ATRs) were discarded even though they also operated under the same Part 121 commercial carrier rules and, as the same carriers seen in this report, shared the same materials in wiring insulation types and insulation blanket (batts) used in their ‘big cousins’.

 

    Under reporting is a big problem and as NASDAC had noticed, there are significant limitations to the self-reporting processes and such may apply in the Aviation Safety Reporting System Database (ASRS) Reports used here.  The same limitations may well apply to the newly announced system by the White House in late January 2000 dubbed the Aviation Safety Action Program (ASAP). This encompasses virtually all of the claims cited for the creation of the earlier ASRS system in 1983, including immunity from prosecution and claims for heightened safety awareness and information sharing. 

 

    The NASDAC studies (see source on page 12) also noted that such aviation mishaps subject to self reporting often go unreported because of; (1) by themselves, they may appear insignificant, (2) the event wasn’t intentional, (3) no one is hurt because of back up systems or (4) no collation is seen to other events.  The latter may easily be attributed to lack of information sharing, which ironically, is why these programs were set up in the first place.  Never-the-less, NASDAC agrees the actual calls placed to ASRS are but a fraction of the industry incidents and occurrences.

 

    Moreover, NASDAC made note of the Heinrich Pyramid (see source on page 15) whereas for every given major accident, there will be 3-5 less significant accidents, and among 7-10 incidents, there may be at least several hundred unreported occurrences. Thus, with the ASRS voluntary reports here, unreported incidents may have ranged considerably higher.

 

    The FAA’s Service Difficulty Reporting Lastly, a separate IASA Study demonstrated that within the Office Of System Safety Databases, and all linked to a common search engine, that the FAA Incident Data System Reports reflected but less than 5 % of the combined reports from the other databases listed there.
