Definition
The work of inspecting, servicing, and fixing an aircraft to keep it safe and airworthy. Repair refers to correcting damage or restoring something that has failed or worn out, while maintenance refers to the routine, scheduled work that keeps the aircraft in continued airworthy condition. In aviation, this work is regulated and must be performed or supervised by appropriately certificated personnel, with required entries made in the aircraft's maintenance records.
Plain English
Keeping an aircraft in safe, working order — both fixing things that break and doing the regular checkups and servicing that prevent problems.
Context Anchor
Seen in training discussions about aircraft condition, preflight decisions, logbook records, and whether an aircraft is ready for a planned flight.
Derivation
‘Repair’ comes from the Latin reparare — ‘to make ready again.’ ‘Maintenance’ comes from the Latin manu tenere — ‘to hold in the hand,’ later meaning ‘to keep up.’ Together they describe both restoring an aircraft after something fails and keeping it in good condition so failures are less likely.
Why Pilots Care
Ensures the aircraft meets regulatory standards and reduces the risk of mechanical failure during flight.
Intuition Check
Do not read this as casual fixing or routine cleaning. In aviation, repair and maintenance of aircraft has safety and legal meaning: the work must be done correctly, by an authorized person when required, and recorded properly.
Example Sentence 1
