The main difference between a 100-hour inspection and annual
inspection is that the airframe and power plant mechanic can sign
off the 100 hour but the annual sign-off requires inspection
authorization. While an in-flight operational check may not be
required it is very worthwhile. The pilot making the flight should
sign the logbooks.
