All Inspections are
done off the tach.

<<<I'm looking for some input from the collective wisdom of the LML. What do you think? The ol' hobbs or the new-fangled SFS timer? Or are both equally as good?>>>

Geeeez, I do my inspections off the calendar flip at fiscal year end... And, I fix everything as it breaks - 100 hours or not.  My Hobb's meter comes on with the master switch - Thus, I got my FAA mandated 40 hours logged pretty quick.  Tach time shows about 600 hours and the Hoobs about 850 - Maybe next year I can park with the 1000 hour experimentals at OSH if I run my battery down a few times more. 

 

Tach time is for engines, Hobbs is for the loving abuse I give my airframe, aloft or otherwise.  Actually, I should count cycles since my brakes and wheels only understand the sweet kiss of the pavement....  I know that my wing leading edge maintenance it based on bug and trash impingement levels - the canopy is only cleaned when the reported visibilty is greater than how far I can see.

 

I write down both values in my log books so that the accident investigator will be confused. 

 

PS- 100 hrs in a J3 is somewhat different than 100 hrs in a Lancair.
