A published headline dated 3 October 2019 says ATC had identified the cause of a transformer explosion on 19 July as a part failure, which it called a very rare event. The article itself could not be retrieved, so the site, the outcome and any further detail are not known from this source.

The headline attributes the explosion to a part failure. No further description of the part, or of how it failed, is available.

  1. A reported cause should be recorded only at the level the source actually states.
  2. A rare part failure still warrants a check of similar equipment once the failed part is identified.
  3. Headline-only reports should be rechecked when a full account becomes available.
