FAR Part 139 establishes safety standards in the movement area and requires that self-inspections be conducted to monitor compliance to those standards. The daily self inspections normally involve two inspections each day to cover both day and nighttime conditions. In order for a self-inspection program to be successful, several factors must be present:

1. Airport management must continuously emphasize the importance of the self-inspection program and monitor its effectiveness.
2. Airport personnel must be familiar with the Part 139 requirements, the ACM/ACS procedures, ground vehicle procedures and communications, and marking, lighting, signage standards.
3. Effective inspection techniques must be established along with a system for reporting and promptly correcting unsatisfactory conditions.
