inspect the flight control surfaces, slats, spoilers, tabs, flaps, mass balance weight attachments, hinge brackets, tracks and rollers;

inspect the flight control system bellcranks, push pull rods, torque tubes, cables, fairleads, turnbarrells and pulleys;

inspect the wing and empennage to fuselage attachments and surrounding structure;

lubricate as necessary.

Take the following action in relation to the fuselage:

inspect the fuselage skin for evidence of wrinkles, buckles, sheared or loose rivets, corrosion, disbonds and general damage;

inspect the areas around cut‑outs (such as windows and inspection apertures) for cracks and inspect the sealing and fit of all doors and emergency exits;

inspect the interior;

inspect the strength of the fabric covering on surfaces;

inspect the internal structure;

inspect the locks, latches and hinges of doors, canopy, windows which may be opened and direct vision windows;

check that the windshields and windows are clean and free from crazing, cracking, discoloration, delamination and scratches;

inspect the seats, seat attachments, seat adjustment mechanisms, seat stops, seat belts, safety harnesses and inertia reels;

inspect the control wheels, control columns, rudder pedals, control levers, control system bellcranks, push pull rods, torque tubes and cables;

operate all trim controls through the complete range of travel and check them for correct trim position indication;

inspect the brake master cylinders, brake lines, reservoirs, parking brake linkage and mechanical brake system operating mechanisms;

check the cabin fire extinguisher for correct charge, legibility of operating instructions and condition of locking pin or seal and ensure that the extinguisher has not reached its expiry date;

inspect the heating and fresh air system ducting and outlets and the airflow control valves;

inspect the emergency and flotation equipment and ensure that the equipment has not reached its expiry date;

lubricate as necessary.

Jack the aircraft so that the landing gear is clear of the ground and take the following action:

inspect the undercarriage attachment to the airframe;

inspect the structural members, drag and side braces, compression members, oleo struts, bracing struts and torque links;

inspect the leaf or tube spring shock absorbing units and bungee rubber;

inspect the flexible hoses;

inspect the main wheels and tyres and the nose or tail wheels and tyres;

clean the wheel bearings, check that they are free from scoring and brinelling, re‑lubricate them, re‑install them and adjust the bearing pre‑load;

inspect the brake linings or pads and the brake drums or discs;

inspect the brake lines and flexible hoses;

inspect the nosewheel or tailwheel steering mechanism and the shimmy dampener;

inspect the landing gear retraction mechanism, the door and the door operating linkage;

carry out an operational check of the landing gear and doors and ensure that the adjustment of downlocks, overcentre links, uplocks and spring tensions are within the manufacturer’s specified limits;

lubricate as necessary.

Take the following action in relation to the fuel system:

inspect the fuel tanks (where visible), lines, drains, vents, signs, filler caps, filler cap securing chains or cables, filler cap seals and scupper drains;

inspect the fuel selector valves;

inspect the fuel selector valve operating linkage.

Take the following action in relation to the hydraulic system:

remove, clean, and refit the hydraulic system filter element, or if it is unserviceable, install a new filter element;

inspect the hydraulic system reservoirs, powerpack, accumulators, selector valves, hand pump, pipelines and flexible hoses.

Inspect the anti‑icing and de‑icing systems.

Inspect the air‑conditioning evaporator, condenser and compressor and the air‑conditioning ducting, pipelines and units.

Inspect the pressurisation control system and indication system.

Take the following additional action if the aircraft is used in agricultural operations:

inspect the hopper, hopper lid and fasteners, baffles and internal braces;

inspect the spreader, spreader gate and controls;

inspect the spray pump fan, fan mount, fan brake, spray pump lines, booms and boom supports;

inspect the emergency dump doors and dump controls.

Take the following additional action if the aircraft is a seaplane:

inspect the external covering and internal structure of the floats or hull;

drain the bilge compartments, refit and re‑lock the drain plugs;

inspect the float attachment struts, bracing wires and attachment fittings;

inspect the water rudders, water rudder attachments and water rudder controls, operate and check them for full and free movement in the correct sense and for correct locking;

inspect the protective treatment and finish.
