Issue Status Justification

The actions taken by the operator address the key concern of the safety issue, that being the supervision of pilots recently trained/authorised in a new specialist task. The mandated extension of command under supervision time, the introduction of periodic consolidation flight checks and the mandated extension of mentoring time are all expected help better prepare newly trained pilots for solo operations and provide them with additional defences to the hazards associated with specialist flight tasks

Action description

On 4 November 2020, the ATSB were advised that Aeropower had taken the following proactive safety actions:

Specifically relating to the supervision and review of newly authorised pilots in specialist tasks, Aeropower has made the following amendments to our procedures:

  1. Mandated and expanded In Command Under Supervision (ICUS) time requirements for pilots as part of initial task training for relevant specialist tasks.
  2. The introduction of consolidation flight checks at key points for pilots newly authorised in relevant specialist tasks. These have been identified as primary, secondary, and tertiary checks.
  3. The introduction of a requirement for pilots newly authorised in relevant specialist tasks to be rostered with an experienced pilot to act as a mentor for their first tasking as PIC on the specialist task.

For cable stringing, the new requirements include 2,500 hours minimum as pilot in command, 100 hours on type, 200 hours low level flying, 200 hours on other powerline operations. Additional supervision requirements include;

  • 10 hours in command under supervision (ICUS)
  • Primary consolidation check at 1-20 hours
  • Secondary consolidation check at 30-50 hours
  • Tertiary consolidation check at 75-100 hours
  • Operational proficiency checks pre tasking.
