Qantas has pulled three its Boeing 737 fleet from service after finding hairline cracks in the "pickle fork" structure between the wing and the fuselage.
"These aircraft have been removed from service for repair," Qantas said in a statement on Friday.
Qantas earlier this week found one example of cracking in an aircraft with just under 27,000 cycles and identified the other two during an audit of 33 of its 75-strong Boeing 737 fleet.
