This is what I have on the subject...
"A" checks - Performed every 100 hours of operation. Surface examination of skin, brakes, wheels & tires, and engine components are tackled, often in a single day if no corrective measures are required.
"B" checks - Incorporating all the steps of an "A" check, the "B" check, often at 500-hour intervals, provides for more detailed examinations of interior spaces and the engines. It may require some disassembly of airframe over the one to two day process.
"C" checks - Performed every two to three years, the "C" check involves all elements of the "A" and "B" checks, substantial airframe disassembly and detailed engine examinations. It often lasts a week or longer.
"D" checks - Undertaken only on six to eight years cycles, the "D" check is the most involved, requiring complete structural and systems examination and testing, including engine removals, and often results in a virtually rebuilt aircraft after several weeks in the maintenance hanger.
Well, that's it. There are no "E" checks...yet. Hope this helps. Regards.

the checks are all asighned different names by the operators but a c check will generally be minor heavy maintenance with the a/c on the ground for about 1-2 weeks and a d check will be heavy maintenance where the a/c will be almost gutted and receive all of the deep maintenance that it needs such as the floors will all be up and structural inspections etc.
hopr that this was of some help if youy want to check it out on the net i guess that your best bet would be wit a/c maintenance companys.
