Communication
Getting the message across
Communication in maintenance is both vertical (management to shop floor and back) and lateral (between technicians, shifts, trades, and with flight crew or operators). Failures here are among the most frequent error precursors.
Means: verbal (face to face, radio, telephone), written (task cards, logbooks, technical logs, emails, safety messages) and non-verbal (body language, signage). Each has weaknesses: speech is fast but transient and distorted by noise or language; writing is durable but can be ambiguous or omitted.
Good practice: use standard terminology, be brief and specific, and confirm understanding with read-back or hear-back for critical instructions. Avoid jargon and slang; if English is a second language for either party, slow down and confirm. Watch the authority gradient - a junior may not question a senior, so seniors must invite questions.
Work logging and recording must be contemporaneous, legible, permanent, unambiguous and truthful; done, OK or a bare signature is poor recording. Deferred defects, parts fitted and torque values must be identifiable. Never certify work you did not do or see.
Keeping up to date and currency means recent, relevant experience on type plus review of amendments, service bulletins and mandatory training. Knowledge decays and procedures change.
Dissemination of information means safety information, incidents and lessons learned must reach the people who need them - a notice on a board nobody reads is not dissemination.
Traps
Watch for answers relying on memory (he told me verbally) where a written record is required, or assuming a briefing was understood because it was given.
Rule of thumb: if it is not written down, it did not happen; if it cannot be read back, it has not been communicated.
