Overview

We’d like your feedback on proposed changes to the Part 139 Manual of Standards (MOS) relating to access to the Obstacle Restriction Area (ORA) of an aerodrome. There are key safety and maintenance activities that need to occur frequently within the ORA, particularly the Runway Strip. The Part 139 MOS unintentionally restricts these activities by requiring written approval by CASA.

Following a review of the detail in the Part 139 MOS, we are proposing significant changes to subsection 6.21 (3) of the Part 139 MOS that would allow certain types of activities to be conducted within the ORA at controlled and non-controlled aerodromes.

Clear restrictions and directions are provided in the proposed revised subsection 6.21 (3) of the Part 139 MOS (refer to the Related documents below).

By removing the requirement to seek approvals or exemptions for certain activities, the changes will:

• reduce administrative burden and cost to industry
• reduce delays to operations
• provide enhanced efficiencies for aerodrome staff.

For further detail on the proposed changes please read the summary of proposed change on CD 2410AS.
