If you think driving while talking on a cellphone is dangerous, what about flying?

A Johannesburg pilot found out when a cellphone call distracted him during preflight checks, leading to an error that resulted in a midair emergency.

The call meant both engines of his Cessna 421C were feeding from the right-side fuel tank as he took off from Lanseria Airport in August 2021, bound for Ondangwa Airport in Namibia.

As he climbed to 13,500ft over Pilanesberg Airport, the pilot noticed the left wing was consistently dropping.

“The pilot declared an emergency by broadcasting a PAN-PAN call and a Mayday call to Lanseria air traffic control,” said a Civil Aviation Authority limited serious incident investigation report.

He was directed to make an emergency landing at Pilanesberg, near Sun City, and found the left fuel tank was still full while the right tank was severely depleted.

The pilot told a CAA investigator that he had been distracted by a cellphone call while going through the preflight checklist.

The report said the cause of the aircraft flying with its left wing low was a fuel imbalance. “Pilots should ensure that there are no distractions such as active mobile phones during operation of aircraft,” it said.

After refuelling the right tank at Pilanesberg, the aircraft continued its journey to Namibia.
