1) In climatic temperate areas without corrosive or severe atmosphere, periodicity of product applications will be as follows :
- Areas 100, 200, 300, 500, 600, 700 (exposed to bad weather) : every 6 months or 500 hours, whichever occurs first
- Areas 100, 200, 300, 500, 600 (not exposed to bad weather) : every year.
NOTE : For the aircraft stored under shelter, the periodicity could be respectively brought to 1 and 2 years.
2) For aircraft often operated or stored in corrosive or severe atmosphere, periodicities will be as follows :
- Areas 100, 200, 300, 500, 600, 700 exposed to bad weather : every 2 months
- Areas 100, 200, 300, 500, 600 not exposed to bad weather: every 4 months
NOTE : For the aircraft often used and stored in corrosive or severe atmosphere, perform every 6 months the lubrication operations planned during annual inspection (Al).
