Second Qantas flight in two days suffers midair mechanical issue

A Qantas Airways Ltd. flight to Fiji turned back to Sydney with a possible mechanical problem, a day after another of its jets issued a mayday alert due to engine trouble en route from Auckland.

Flight QF101 returned to Sydney after pilots received a fault indicator about a potential mechanical issue, Qantas said Thursday. The airline operated a Boeing Co. 737 for the flight, the same model involved in Wednesday’s incident.

Qantas said the crew followed standard procedure and the aircraft landed normally. QF101 didn’t require a priority landing and the fault indicator didn’t relate to an issue with the engine, it said. Engineers will examine the plane.
