Heston MRO had not yet implemented a previously proposed and accepted method to account for tooling and equipment (such as pitot probe covers) prior to aircraft pushback.
The ATSB is satisfied that when implemented, the safety action taken will adequately address the safety issue.
In January 2024, Heston MRO advised that they would be completing a review of their transit toolbox procedures, with any changes to be implemented when a new revision of their manual was released in January 2024. The changes will incorporate a more specific requirement to review and document a check of the transit toolbox prior to certified release to service, which will include the use of a checklist.
