South Korean regulators have completed inspection on country’s 150 Boeing 737NGs for structural cracks at “Pickle Fork”
Earlier, the Federal Aviation Authority (FAA) issued guidance stating that planes with 30,000 flight “cycles” have to be re-inspected within 60 days. Plane with more than 22,600 cycles need to be inspected within 1,000 more cycles.
South Korean regulatory ministry states that two 737-800s found to have cracks on “pickle fork” and repaired and returned to service. One belonged to Jin Air, the other Korean Air. The remaining 11 737s are still on track to return to service by January next year.
South Korea’s transport ministry said last month that nine Boeing 737 NG planes in the country had been grounded after checks found structural cracks requiring repairs.
Boeing said more than 1,100 planes have been inspected so far, of which around 5 per cent were found to have this cracking.
“pickle forks” are the structural component that attach the plane’s body to its wing structure. These components help to “manage the stress, torque and aerodynamic forces that bend the connection between the wings and the body of the jet”.
