I have performed a number of Safety and Security Audits to JAA standards granted the last was about 4.5 years ago and ACCRA failed to comply with the greater majority of the basic requirements. I have to pose the question that if they are unable to police the ground operation then they might have some difficulty policing the airline/ aircraft requirements.
The JAA is not responsible for establishing security requirements or aerodrome standards. Even if it did they would not apply to Accra. It would be interesting to know exactly what these audits covered and what responsibility the GCAA had in the matter.
