Johannesburg  — SAA and Comair began returning grounded planes to service a day after SA's air safety regulator flagged maintenance problems.

Flights were departing OR Tambo international airport as normal on Wednesday, a passenger service representative for Airports Company SA said.

Comair said it expected no disruptions, after at least eight of its domestic flights were hit on Tuesday.

SAA, which had 25 aircraft affected by the safety audit, did not respond to an e-mailed request for comment.

The SA Civil Aviation Authority (Sacaa) said it had found faults during an inspection at SAA Technical (SAAT). It issued a prohibition order until these had been fixed but did not disclose what they were.

Sacaa official Luvuyo Silandela told state broadcaster SABC that the regulator had found that work done by SAAT had been signed off by engineers “who do not hold the specific ratings to release that work”.

The regulator also had concerns about maintenance checks on components such as the flight data recorder and cockpit voice recorders, Silandela said, adding that he wished to dispel allegations that SAAT had used fake parts in planes.

The Sacaa, which did not respond to e-mailed requests for comment, said it had accepted a corrective action plan from SAA’s maintenance unit and that the decision by SAA and Comair to “self-ground” some aircraft was a precautionary measure.

The lack of clarity over the exact nature of the faults at SAAT has led to speculation from analysts that the regulator had found serious infringements.

SAAT maintains aircraft for SAA, its subsidiary Mango Airlines and British Airways franchise partner Comair, which also operates under the kulula.com brand.

Mango Airlines flights had left Johannesburg for Cape Town on time on Wednesday, its website showed.

SAA, which has not made an annual profit since 2011 and is dependent on government bailouts, cancelled four domestic flights on Tuesday, combining services and deploying bigger aircraft to accommodate affected passengers.
