What a CAA Part 145 approval means for your aircraft
Part 145 is the benchmark for aircraft maintenance organisations. Here's what the approval actually covers — and why it matters when you choose a workshop.
When a workshop describes itself as CAA Part 145 approved, it means the organisation has been audited and approved by the UK Civil Aviation Authority to carry out maintenance on aircraft, engines, components and avionics — and to certify that work under its own approval.
What the approval covers
A Part 145 approval is not a single blanket permission. The approval certificate lists the exact scope of work the organisation may perform: which aircraft types, which systems, and which kinds of maintenance. Our approval covers the full ranges of Piper, Robin, Cirrus, Cessna and Socata, alongside other single and multi-engined light aircraft.
- Airframe and engine maintenance on light single and multi-engined aircraft
- Annual inspections and scheduled checks
- Avionics installation, testing and repair
- On-aircraft radio, compass and instrument system maintenance
Why it matters to owners
Work certified under a Part 145 approval is carried out by appropriately licensed engineers, using controlled procedures, approved data and calibrated tooling. Every task is recorded and traceable — which protects the value of your aircraft and keeps its paperwork in order for insurers, buyers and the regulator.
