Australia’s aviation engineering union has called on Qantas to ground its entire Boeing 737 fleet after a crack was discovered on a second aircraft overnight. 

The airline said yesterday it would immediately inspect 33 planes after a crack was found during a scheduled maintenance check. 

The Australian Licensed Aircraft Engineers Association said both cracks were on a part of the plane called the ‘pickle fork’, which holds up the wings. 

ALAEA boss Steven Purvinas says the aircrafts should not be flying. 

“As long as Qantas is unaware which aircrafts do or don’t have cracks, they should ground the entire fleet until they know which are safe to fly,” Mr Purvinas said.
