Definition
An operating event in which an engine parameter — such as temperature, pressure, torque, RPM, or time — has gone beyond a published manufacturer or regulatory limit. Exceedance conditions must be recorded and typically require inspection, maintenance action, or component replacement before the engine is returned to service.
Plain English
A moment when something the engine is doing — how hot, how fast, how hard, or how long — went past the allowed limit. When that happens, the engine usually has to be checked or worked on before it can be flown again.
Context Anchor
Seen in maintenance manuals, engine monitor records, aircraft logbooks, and maintenance write-ups after a published operating limit has been exceeded.
Derivation
From the verb 'exceed,' meaning to go beyond a set point. The '-ance' ending turns it into a noun describing the event itself. So an 'exceedance condition' is simply the condition of having gone past a limit — useful here because it names the event, not just the act.
Why Pilots Care
An exceedance condition signals potential engine stress that may require inspection, component replacement, or airworthiness review before further flight.
Intuition Check
An exceedance condition does not automatically mean the part has failed. It means a limit was crossed, and that crossing must be handled as a maintenance issue.
Example Sentence 1
After the hot start, the technician reviewed the engine data and confirmed an exceedance condition on the turbine inlet temperature.
Example Sentence 2
Maintenance reviewed the exceedance condition in the torque log and scheduled a borescope inspection.
