The issue isn't whether and item is of "vital importance", or whether it is simple to fix. The issue is whether an owner/operator holds the privilege to perform a task.

asking a question which should not bring the wrath of usenet upon him
(lotsaluck!) nor does it indicate any kind of disregard for the FARs.
