task card
The individual instruction a technician works to: the task, the steps, the required authorisation and the sign-off.
Why it matters
Cards are where findings appear. A card that can be closed with a finding still open is the single most common way an open item disappears.
In AerSynx
A card closes only when the signer's authorisation, stamp, licence and recurrent training are valid on the day of the sign-off — checked when the card is closed, not by a reminder. Work Orders and Work Cards →
