Qantas grounds 3 Boeing 737s due to hairline cracks

SYDNEY, AUSTRALIA - MARCH 14: A Qantas commercial plane taxis to a runway at Sydney Airport on March 14, 2019 in Sydney, Australia. The Civil Aviation Safety Authority (CASA) has suspended operations of the Boeing 737 MAX 8 in Australia following a deadly crash that killed 157 people in Ethiopia on Sunday 10 March. Up until CASA's decision Fiji Airways was the only airline flying the Boeing 737 MAX 8 aircraft in Australia after Singapore's SilkAir announced it was temporarily ground its six aircraft on Tuesday. Safety concerns about the model of aircraft were first raised in October 2018 after a Lion Air flight in Indonesia crashed, killing all 189 people aboard. Since Sunday's crash in Ethiopia, Boeing has announced plans to update the aircrafts software. (Photo by Cameron Spencer/Getty Images)

CANBERRA, Australia — Australian airline Qantas Airways said on Friday it grounded three of its Boeing 737s over hairline cracks found in wing structures but expected to have them flying again this year.

The airline has been inspecting its aircraft following calls this month from the U.S. Federal Aviation Administration for all airlines to check Boeing 737 NG planes that had completed more than 30,000 takeoff and landing cycles for cracking in a part that helps keep wings attached. These are different from the 737 MAX jets, which were grounded worldwide earlier this year.

Qantas Domestic and Freight Chief Executive Andrew David said the airline had examined in a week all 33 jets of the fleet of 75 that had completed more than 22,600 cycles in two and a half years of flying.

The hairline crack was found in one of eight bolts in the so-called pickle fork assembly in each of the three planes.

“Minimal risk, we are being very prudent, we’ve done the checks in seven days,” David told reporters. “Those three aircraft are on the ground. We will get them back flying by the end of the year.”

David said the airline would “have to make some minor schedule changes” while the aircraft were repaired.

David criticized the Australian Licensed Aircraft Engineers Association, the body representing the workers who carry out the checks, for calling on Thursday for all 75 of Qantas’s 737s to be grounded while they were inspected.

“We’re very, very disappointed. They’ve completely misrepresented the facts,” David said. “If they were genuine about their safety concerns, why not work with the regulators? Why not work with the industry?”

David questioned why the association had not also called for rival domestic airline Virgin Australia to ground its fleet of 77 jets.

Virgin said on Friday it had inspected 19 of its 737s and found no cracks.

Qantas said it was working with Civil Aviation Safety Authority, the Australian aviation industry regulator, and Boeing to resolve this issue, which involved complex repair work.

U.S. congressional hearings this week have produced internal Boeing documents showing that company employees raised concerns about the design of a key flight-control system and the hectic pace of airplane production long before two 737 MAX jets crashed, killing 346 people.
