    Most likely the same thing as the odometer in your car. It would roll over to 0000.0 and keep going.

    The 172 in our club has 14,000+ hrs on the air frame and the Hobbs meter shows 4,000+.

    Exactly what withanh said. The 172RG I fly had this happen a couple months ago. While the Hobbs only says about 250, then we record 10,250. Not too complicated.

    Watch out!

    After ten thousand hours, the aircraft will become SELF AWARE and begin killing every human it can. At my local airport, when the Hobbs reaches 9900, we have to get ‘good old Betsey’ (shotgun) out and have the plane put down. It’s a sad day. But once a plane breaks their leg there is little that can be done. Better they don’t suffer and put them out of there misery. (sniff)
