Notice 2024/2: Obstacle Assessment Service Providers
Refer to AIC 001-2024, effective 22 April 2024
The purpose of this AIC is to communicate and advise obstacle assessment applicants of the approved service providers under Civil Aviation Regulations Part 178, which will be responsible for the assessments of obstacle applications.
According to the Civil Aviation Act 13 of 2009, the South African Civil Aviation Authority (SACAA) is mandated to regulate all aviation activities to ensure the safe, secure and environmentally compliant efficient conduct of civil aviation activities within the State. The obstacle assessments, currently being conducted by SACAA, are seen as a service provision function, which is not in accordance with the Authority’s mandate.
In compliance with Civil Aviation Regulations Part 178, the CAA has approved a service provider that will be responsible for the assessment of all obstacle applications, and it is in the process of approving more service providers under the same regulations. The current service provider has met all the requirements, as outlined in CAR Part 178, and has been duly approved to perform this function.
Note that from date of publication of this AIC, the SACAA will no longer be accepting any applications for assessment of obstacles, as it will be assuming the oversight role, of reviewing assessments conducted by Part 178 approval holders, in accordance with the applicable regulations. Therefore, all new applications must be lodged with the approved obstacle assessment service providers. The list and contact details of the approved obstacle assessment service providers are listed below:

Wind Farm Obstacle Lighting
Guidance regarding obstacle lighting on Wind Turbine Generators under construction
The turbine structure under construction is considered to be a temporary structure due to the building activity i.e. cranes etc. around it. As such an interim lighting system is required to be implemented. Temporary obstruction lighting in the form of a Type B (low intensity) 32 candela red flashing light system, situated at the highest point of the structure in progress would suffice for the construction period. This lighting system is to be provided to each turbine structure. It is recognised the interim lighting system will be flashing randomly, hence the requirement for each turbine structure to be identified.
The temporary obstruction lighting must be brought into play at 25m and continue to be displayed at the highest point, until such time as the required permanent obstruction lighting system is on line. It is understood that the wind farm site will not be connected to the national grid, until such time as it becomes operational, hence the concession of the interim lighting systems. There are solar powered systems available off the shelf, which would be adequate for the purpose.
Developers of Wind Farm Sites are reminded to advise the ATNS timeously (at least 6 weeks in advance), of construction commencing, in order for that information to be circulated into the aviation environment
