Many passengers have been left stranded in airports across South Africa following compliance checks by the Civil Aviation Authority (CAA) which has recalled several airplanes in the country.

The periodic safety spot checks affected major headlines including Comair and British Airways. Also, South African Airways, has in accordance with the directive, either recalled or cancelled some of its flights.

Stranded passengers have voiced their displeasure over the exercise, saying they have not been informed ahead of time. But authorities say the grounding was “related to irregular findings picked up during a recent audit of our maintenance and technical service provider, South African Airways Technical.”

Transport Minister assured passengers that their safety was paramount and that the checks were meant “to ensure that our airlines meet the safety standards.”
