The OEM will issue updates to maintenance recommendations in form of normal and temporary revisions several times per year. The maintenance program may also need to be updated based on AD’s and ASB’s as well as changes to instructions for continued airworthiness linked to STC’s and modifications.

In order to ensure the highest level of flight safety as related to verification of airworthiness, the time from the issue of a change to maintenance requirements until incorporation in the maintenance program should be kept to an absolute minimum.

Additionally, in many cases a revision contains changes which remove tasks and escalate intervals. The operator will only see the positive impact from this in his maintenance planning, after incorporation in the maintenance program.

ACS can provide a full and efficient revision service for the maintenance program.
