He referred me to 65.81 General privileges and limitations (a). I gently pushed back as 65.81 was dealing with "certificated mechanic" and as such I didn't believe that was applicable. He still disagreed...
I’ve heard of that before. Its purely his opinion, but I believe it was meant in a positive way.
Regardless, in general, aircraft maintenance tasks are “classified” into different groups.
There are tasks that do not “raise up to the level” or are not defined as preventive mx or maintenance which include cleaning, refueling, giving opinions and so on. Those items require no training/experience or record entry.
Next are preventive mx tasks which are defined by Part 1 and Part 43, require a minimum of a PPC and a record entry, but no prior experience or training. Part 65 does not apply.
Maintenance tasks on the other hand are defined as: inspection, overhaul, repair, preservation, and the replacement of parts, but excludes preventive maintenance. Alterations and rebuilding are also separately included at this level. Part 65 prior experience or proven ability is in play as well as a number of other FARs, requires an A and/or P or repairman certificates, and all maintenance requires a record entry.
Fortunately, there is plenty of guidance on several levels that can assist in navigating this topic. But I wouldn't be "gentle" next time and insist on a reference or his "professional" opinion on why Part 65 is applicable to a PPC performing preventive mx per Part 43.
