Bonanza's don't even have recording tachs anymore. All they have is the
hobbs. My plane is similar, but it's on the gear so I don't pay for taxi.

Interesting. So Hobbs time is what gets logged in the aircraft/engine
logbooks?

Exactly. Time in service.

Context please? Every engine/airframe log book I've ever seen (small, single
engine) is based on tach time.

You won't find the words "Tach Time" anywhere in the regs.
The rules say "time in service." Actually most maintenance
entries don't require the time to be recorded at all, just
the date.

The definition of time in service from Part 1:

Time in service, with respect to maintenance time records, means the
time from the moment an aircraft leaves the surface of the earth until
it touches it at the next point of landing.

A squat switch / hobbs is a better indication. However, recording
tachs are cheaper and more common and the FAA has always allowed them.
