Across these chapters the manual gives a complete picture of the EXTRA 300LT airframe and its systems. It opens with the general description and airworthiness limitations, then moves into the scheduled maintenance programme — 25, 50, 100, 200, 300, 400, 500 and 1000 hour checks, plus the 1000-hour Significant Items Inspection. From there each system is covered in turn: the steel-tube fuselage with its composite covers, the fibre-composite wing and stabilizers, the push-pull and cable flight control system, the hydraulically operated Cleveland disc brakes, the Lycoming AEIO-580-B1A engine installation with its Christen inverted oil system, the MT-Propeller three-blade constant-speed propeller, the fuel system with its center, acro and wing tanks, and the full electrical and indicating system. Repair guidance for composite and steel components, control surface balancing data and a comprehensive torque value section are also included.

What This Extra 300LT Manual Enables
This is not a general aerobatic aircraft book. It is the EXTRA 300LT service and repair manual as issued by the manufacturer, and it supports real maintenance work on this specific type. A technician can use it to plan and carry out the full scheduled inspection programme, to remove and reinstall the wing, stabilizers, flight controls, landing gear and engine, to rig the aileron, rudder and elevator systems, to adjust the trim tab, to bleed the brakes, to service the inverted oil system, to diagnose fuel and indicating faults, and to repair composite structure to the correct layer sequences and cure cycles.
The manual also contains the values that make the difference between a correct job and a dangerous one — control surface deflection tolerances, torque values for the main spar bolts and landing gear clamps, brake disc wear limits, tire pressure, fuel and oil capacities, composite temperature limits, and the life-limited component replacement times. For an aircraft used for aerobatics, where airframe and control system stresses are high, having these figures on hand is essential.
Who This Manual Is For
Licensed airframe and powerplant mechanics, aircraft maintenance organisations, owner-operators who maintain their own aircraft, and engineering students studying the EXTRA 300LT will all find this document directly useful. It is written for trained personnel who are already familiar with aircraft maintenance practice, and it assumes access to the relevant Lycoming, MT-Propeller, Christen, Cleveland and avionics vendor publications for component-level overhaul.
Get the Extra 300LT Maintenance Manual
Every procedure, tolerance and specification in this 432-page Extra 300LT aircraft service manual is delivered as an instant PDF download — no shipping, no waiting. Open it on a laptop, tablet or phone in the hangar, print the pages you need for the job at hand, and keep the complete document on file. Whether you are performing a routine 100-hour inspection, chasing an electrical fault, rebuilding a landing gear leg or repairing a composite panel, this Extra 300LT repair and maintenance guide gives you the manufacturer’s own instructions in one place.
