What engine does the Cessna 525C have?

Most have the Williams FJ44 (98% of those registered).

What are common problems with the Cessna 525C?

In 99 Service Difficulty Reports filed with the FAA since 2016, the systems reported most were turbine engine compressor section, fuselage, landing gear attach fittings, ac generator-alternator, and the part most often reported was a fractured rotor.

Airworthiness Directives

10 current ADs name the 525C airframe, 2 with a repeat action; 2 more were superseded. Its engines carry 3 more. 1 equipment AD names the model.

The ones that come back

ADs with a repeat action: an inspection or replacement at an interval, for as long as the AD applies. These are the airworthiness costs an owner keeps paying.

From the NTSB's aviation accident database, refreshed monthly; accidents only, homebuilts left out. Counts, not rates: nobody publishes how many hours each model flies, and a training fleet flies far more than a private one. Look up any case by its number in the NTSB's CAROL.

Before you buy one

Run its N-number through the AD check: every AD that names its airframe and engine, as a checklist to take to the logbooks.
For each repeat-action AD (2 on the airframe), find the last compliance in the logbooks and when the next one is due.
Compare the engine's time since overhaul with its maker's published overhaul time, and look for the reason behind any long gap in flying.
Ask the mechanic doing the pre-buy to look hard at the turbine engine compressor section and for fractured rotors: they are what gets reported most on this model.
1 equipment AD names the 525C (a muffler, a seat belt, a display): find out which of that equipment is installed.
Check the registration, the airworthiness certificate and the date of the last annual inspection.
Work out the sales or use tax your state will charge with the aircraft tax calculator.
