Communication

Within and between teams, work logging and recording, keeping up to date, dissemination of information, electronic communication.

Notes

Communication, summary notes

Main ideas
  • Communication failures, within a shift, between shifts, and between maintenance and flight crew, are one of the most common contributing factors in maintenance-related occurrences.
  • Shift handover must be explicit and in writing (not just verbal), covering incomplete work, deferred defects and any non-standard configuration left on the aircraft.
  • Accurate work logging and sign-off create the paper trail that lets the next person (or an investigator) reconstruct exactly what was done, an incomplete log is a communication failure even if the work itself was correct.
  • Keeping current with revised procedures, airworthiness directives and manual amendments is a communication responsibility of both the organisation (distributing updates) and the individual (reading them).
  • Electronic communication (email, electronic work packages) can lose the back-and-forth clarification a face-to-face handover provides, ambiguous electronic instructions should be verbally confirmed for safety-critical tasks.
  • ⚠ Exam trap: an unrecorded verbal handover is a communication failure even when the work itself was done correctly, the technical log is what carries the information across the shift boundary.
Solved examples
  1. A defect is verbally mentioned to the incoming shift lead but never entered in the technical log. The next shift does not action it. What failed?

    Communication relied on an unrecorded verbal handover instead of the formal documented system, the technical log exists precisely so information survives a shift change even if a conversation is forgotten or misheard.

  1. 1. A defect mentioned verbally at shift handover but never entered in the technical log is a failure of:

    Formal, documented communication
    Technical competence
    Tooling
  2. 2. Shift handover for incomplete or deferred work should be:

    Explicit and in writing, not only verbal
    Left to informal conversation
    Unnecessary if the next shift is experienced
  3. 3. Keeping current with revised procedures and airworthiness directives is a responsibility of:

    Both the organisation and the individual technician
    Only the organisation's quality department
    Only the individual technician
  4. 4. Ambiguous instructions received by email for a safety-critical task should be:

    Verbally confirmed before acting
    Actioned exactly as written even if unclear
    Ignored until the next scheduled meeting
  5. 5. An incomplete maintenance log entry, even when the work itself was performed correctly, is considered:

    A communication failure
    Acceptable, since the task was done correctly
    Irrelevant to airworthiness
  6. 6. The highest-risk moment for lost information in maintenance is typically:

    Shift or task handover
    The middle of a task
    The morning briefing
  7. 7. Communication of a partly disassembled or non-standard aircraft configuration must be:

    Recorded and clearly flagged to the next shift
    Left for the next shift to discover
    Only mentioned if asked
  8. 8. Compared with a written record, a purely verbal instruction is:

    More easily forgotten or misheard
    Always clearer
    Legally sufficient on its own
