8.10 - Utilization in Cold Weather (-0 °C to -25 °C) or Very
Cold Weather (-25 °C to -40 °C)
NOTE
Check shock absorber and tire pressure values inside a hangar that is heated
at about 15 °C with control equipment at room temperature.
If a landing is foreseen in cold or very cold weather, or if prolonged operation of
the airplane is anticipated in such conditions, it is recommended to prepare the
airplane as follows:
1. Smear the door and engine cowlings seals with silicone grease, as well as
the leading-edge deicers.
2. Apply engine oil on the engine cowling latches.
3. Inflate the main landing gear shock absorbers to 247 psi (17 bars) at a room
temperature of 15 °C.
4. Position a 0.59 in (15 mm) shim at the bottom of the piston tube and against
the forward landing gear's half-fork to reduce shock absorber travel. Then
refill the shock absorber with hydraulic liquid. Remove the shim and inflate
the shock absorber to 138 psi (9.5 bars) at a room temperature of 15 °C.
5. Inflate main landing gear tires to 130 psi (8.96 bars) and the nose tire to 102
psi (7 bars) at a room temperature of 15 °C.
NOTE
to check pressure values and to inflate tires and shock
absorbers.
Check pressure values and inflate shock absorbers and tires if necessary,
according to
during operation in cold weather only.
