An Air Senegal delegation was in Dar es Salaam this past week for discussions with Air Tanzania officials on how best to take on Pratt & Whitney, the American aerospace company that produces the PW1524G-3 engines used by the planes.

Both national carriers believe that the company is dragging its feet in resolving the longstanding issue of defective engines, leading to mounting losses for the airlines as their A220-300 fleets remain grounded.
