Maintenance of aircraft after each flight
Wash the aircraft and propeller with clean water without any cleaning additions. According to degree of
staining, you can use cleaning additions for places like exhaust pipe, main undercarriage or wheel’s
covers. As cleaning additions you can use automotive one. Organic glass of the canopy had to be
washed very carefully with plenty of water used forward to soften the rests of insect. Wash with soft and
clean sponge without using strength. Drying drops of water can be removed by using wet deerskin.
During washing procedure you can watch for condition of rivet lines, screwed joints, leading and trailing
edges of aero-dynamical surfaces. For cockpit cleaning use vacuum cleaner. We suggest to provide
visual check of intake’s holes in engine’s cowling providing air to engine’s coolers. Founded obstacles
remove carefully. After finishing cleaning of the aircraft, check fuel, oil and cooling liquid volumes. Re-fill
if needed.
There are 7 installed maintenance entries on the aircraft. Two are placed on lower side of
each wing, one at the end of the fuselage and last two on horizontal stabilizer.
Installation guide for hydraulic brake system with closed brake circuit for 6" eco power brake wheels:
Type of brakes:
Single-disc with disc placed in the wheel, with single-piston brake valve, closed hydraulic circuit, one
main brake cylinder with a 16 mm diameter on the control lever or two 14 mm cylinders on pedals.
Brake wheel installation:
Installation - the assembly of brake wheels is usually simple and trouble-free, providing the output
diameter and length of the wheel shaft output, fastened to the aircraft leg, is predetermined. The
wheels are supplied as a set and during assembly the wheel shafts including wheel and brake set are
usually only inserted into pre-made (original) wholes. If dimensions are not arranged beforehand, it is
necessary to adjust the aircraft leg to the dimensions according to the supplied shaft (usually the brake
valves have a horizontal orientation with the piston in the backward direction).
Prior to inserting the wheel shaft into the aircraft leg, the brake disc must be placed in carrier pins inside
the wheel and the brake valve needs to turned so the output for the brake hose is facing in the upward
direction. The wheel set with brake and shaft prepared this way can be assembled to the aircraft leg and
tighten the shaft nut by means of torque, according to leg type. The nut requires a securing pin,
providing it is not self securing. The same method is applied for the assembly of the second wheel.
Note:
Disassembling the entire wheel set with brake is not necessary for changing a tire.
