Feature Article: Repairs

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.

Minor FAR 43.9(a) compliance

Work done, date completed, certificate type/number, signature.

TT (total time) not required

FAR 43.9 requires that the person performing preventive maintenance must record the work in the maintenance records. The record must contain a description of the work, the date of the work, the name of the person doing the work, and approval or disapproval the aircraft for return to service.

Major

Repair stations

FAR 145 for propellers, instruments and avionics
