Microlight air law contains stuff (pilot maintenance, PtF regulations...) not met in normal JAR air law
"Pilot Maintenance" is contained in the ANO (AN(G)R Part 4). I am not aware that the Microlight community have an exemption to this?
Leaflets such as this:

have the Pilot Maintenance 'lifted' from the ANO.
PtF regulations and NPPL privileges form a part of "Aircraft Documentation" and "Licence privileges" which are a part of the NPPL microlight, SSEA and JAR-FCL syllabi. Each instructor community naturally focuses on the type on which training is conducted.
