A miniature air gap inspection device permits in-situ inspection of a generator field and stator core having entrance gaps as little as 0.5" and larger. The inspection device passes through a radial air gap between a core iron and a retaining ring of the generator, and thus, removal of the generator field is not necessary. The device includes a tractor section having a tractor frame attachable to the retaining ring for selective circumferential positioning about the field. A mast section is coupled with the tractor frame and includes an extendible mast. An inspection head is attached to the extendible mast and is axially extended and retracted in the gap by the mast. The inspection head supports at least one inspection tool for performing the in-situ generator inspections.
