 If the aircraft is far from its base and no dry nitrogen is available, you can use air for the servicing of the tires if:

 -the oxygen in the tires is not more than 5% (volume) or
 -maintenance personnel remove the air from the tires and inflate
 them with dry nitrogen before 15 hours time service. A chemical reaction between the oxygen in the tires and the gases from the inner liner can cause a tire explosion.
 (3)
 Put the tire inflation cart near the tire to be inflated.

 (4)
 Remove the tire inflation-valve cap.

 (5)
 Install the tire inflation adaptor and pressure gage on the tire inflation valve. Connect the tire inflation cart to the tire inflation adaptor.

 (6)
 If there is a large temperature decrease between the departure and the destination airports, you must adjust the tire pressure for the colder airport before the flight. If the temperature difference is equal to or greater than 25 deg.C lower, do this procedure:

 (a) Increase the given tire pressures 3.7% for each 10 deg.C of temperature difference.
 EXAMPLE  Temperature at departure airport = 20 deg.C Temperature at arrival airport = -10 deg.C Temperature difference = 30 deg.C
 Increase the tire pressure: 30/10 x 3.7% = 11.1% If the loaded tire pressure is 13.0 bar, increase the tire pressure: 13.0 bar + (13.0 bar x 11.1%) = 14.4 bar

 4. Procedure_________
 WARNING : USE ONLY NITROGEN FOR TIRE INFLATION. IF THE BRAKES OVERHEAT,_______ OTHER GASES CAN CAUSE AN EXPLOSION.
