Continental IO550 Warranty Labor Allowance: How much should engine work on a Cirrus SR22 IO550N cost?
Airplane maintenance is very expensive, there is no way around this. This does not mean your mechanic gets a carte-blanche. The most important advice is to not argue once a bill has been issued, the discussion must happen before the invoice, ideally, before the work is done.
Mike Busch, my favorite airplane guru and mentor, recently published a Q&A on this topic. Worth watching.
I have one additional tip for SR22 or IO550 owners specifically. Continental publishes a warranty-labor allowances table. You can call them directly, or look it up on their website.
These are not the recommended hours, these are the maximum allowed. It's perfectly normal to reference this guide before the work is done, and ask the mechanic if his labor hours will not exceed these amounts. If your mechanic is offended by this notion, get a new mechanic. Remember to allow extra time for decowling and recowling.
It's your plane and your money, don't let other people make decisions on your behalf.
You can find this on Continental's site under Services / Warranty Labor Allowance.
A similar guide is published by Cirrus, however i have not found a copy yet.
