Chapter 12. Publications, Forms, & Records Aircraft Maintenance Manual Although these manuals do not require any FAA approval, the regulations do require that the manual be developed in accordance with industry standards. This ASTM sets that standard by requiring: General specifications including capacities, servicing, lubrication, and ground handling must be listed. An inspection checklist for the annual condition or 100-hour inspection. A description of and the instructions for the maintenance, repair, and overhaul of the LSA engine. A description of and the instructions for the maintenance, repair, and alteration of the aircraft’s primary structure. Other items for which maintenance procedures must be provided are: Fuel systems, Propeller, Utility system, Instruments and avionics, Electrical system, Structural repair, and Painting and coatings, The Inspection, Repair, and Alterations section must specifically list any special tools and parts needed to complete the task, as well as the type of maintenance action (line, heavy, or overhaul) necessary to accomplish the activity. Directly associated with that information is the requirement to specify the level of certification needed to do the job, i.e., LSA repairman, A&P, or repair station. The manual may make reference to existing FAA advisory circulars. Line Maintenance, Repairs, and Alterations The minimum level of certification necessary to accomplish line maintenance is LSA inspection. Some typical tasks considered to be line maintenance are: 100-hour/annual condition inspection. Servicing of fluids. Removing and replacing components when instructions to do so are provided in the maintenance manual.      – Batteries      – Fuel pump      – Exhaust      – Spark plugs and wires      – Floats and skis Repair or alteration of components when specific instructions are provided in the maintenance manual.      – Patching a hole in the fabric      – Installation of a strobe light kit Heavy maintenance, repairs, and alterations can only be accomplished by either a certified mechanic (A or P or A&P) or an LSA repairman — maintenance who has received additional “task specific" training. Some examples of this would be the removal and replacement of the following: complete engine, cylinder, piston and valve assemblies; primary flight controls; and landing gear. Heavy repair of components or structure can be accomplished when instructions are provided in the maintenance manual or other service directed instructions. A few examples of this activity are: Repainting of control surfaces. Structural repairs. Recovering of a dope and fabric. Heavy alterations of components can be accomplished when instructions are provided in the maintenance manual or other service directed instructions. Examples of this activity are initial installation of skis and installation of new additional pitot static instruments. Overhaul of components can be performed only by the manufacturer (or someone authorized to perform) of the LSA or the component to be overhauled. An overhaul manual is required and must be a separate manual from the manufacturer’s maintenance manual. Items typically considered for overhaul are engines, carburetors, starters, generators, alternators, and instruments.
