Although suitable for use in most situations, the streamers attached to the pitot probe covers supplied and used for A350 operations by Heston MRO at Brisbane Airport provided limited conspicuity due to their overall length, position above eye height, and limited movement in wind. This reduced the likelihood of incidental detection of the covers, which is important during turnarounds.
The ATSB is satisfied that the increased length of the pitot probe covers used at Brisbane Airport has adequately addressed the safety issue.
In January 2024, Singapore Airlines advised the ATSB that they had engaged Heston MRO at Brisbane to use pitot probe covers with better conspicuity by increasing the length of the streamers. Usage of such covers has been implemented by Heston MRO on Singapore Airlines aircraft at Brisbane (see images below).
