Part-145 is the EASA approval for organisations that physically perform aircraft maintenance. A Part-145 organisation employs certifying staff who release aircraft to service after work is completed — the hands-on counterpart to the CAMO's planning and management role.
Part-145 is the EASA approval for maintenance organisations — the workshops and line stations that physically perform aircraft maintenance. A Part-145 organisation operates under an authority-approved exposition (MOE), employs certifying staff with defined qualifications, controls its tools, parts and documentation, and issues the Certificate of Release to Service (CRS) after completing work.
The division of labour in EASA's system is clean: the CAMO decides what maintenance is due and when; the Part-145 organisation performs it and certifies the work. Commercially operated and complex aircraft must be maintained by Part-145 organisations, while light aircraft under Part-ML may also use independent certifying staff or CAO-approved organisations for many tasks.
Why it matters for flight schools
For a flight school, the Part-145 relationship shapes fleet availability more than almost any supplier decision. Turnaround time on scheduled checks, honest communication about findings, parts sourcing speed and slot flexibility determine how many days per year each aircraft actually flies. The information interface matters as much as the wrench work: a maintenance provider who receives accurate hours, cycles and defect context plans better — and a school that receives structured work records back keeps its airworthiness file audit-ready.
How FlightLogger handles it
FL Maintenance gives schools and their Part-145 provider a shared, live view of due items, defects and work orders — replacing the email-and-PDF shuffle that delays inputs and loses records.
Frequently asked questions
Is a Part-145 organisation the same as a CAMO?
No. The CAMO manages continuing airworthiness — planning, records, AD control and reviews — while the Part-145 organisation physically performs maintenance and releases the aircraft to service. Many companies hold both approvals, but the functions are legally distinct.
Does a flight school's fleet have to be maintained by a Part-145 organisation?
Complex and commercially operated aircraft, yes. Light training aircraft under Part-ML have more flexibility, including maintenance by CAO organisations or independent certifying staff for defined work — though many schools use Part-145 shops regardless for consistency.
