What owners are reporting
Every squawk posted so far is on this page, and yours will be too the moment you add it. What the bar is counting toward is something different: at 20 airplanes we can start publishing rates for the model as a whole — how often this happens, and at what hours. Until then it stays a list of what real owners hit, because a percentage built on four airplanes is a rumor.
Your own log is free and yours alone. Only the aggregate is ever published, and never by tail number.
Others from Cessna
Fleet figures are from the FAA Releasable Aircraft Database, active registrations only. Registry data is public. Squawk data comes from members and is published grouped by model.
