YUMA, Ariz. (AP) - Inspectors say there are still about 60 Southwest Airlines jets that need to be checked for cracks like the ones that forced an emergency landing in Arizona Friday.
 
Southwest and federal officials say inspectors small, subsurface cracks were found in three more planes that are similar to those suspected of causing Friday's fuselage failure and loss of cabin pressure. No one was seriously hurt.
 
Inspectors say they should be done checking the rest of Southwest's Boeing 737-300s tomorrow.
 
Nineteen other planes inspected using a special test showed no problems and will be returned to service.
 
But the remaining inspections mean flight cancelations will likely continue until the planes are back in the air.
 
Officials say a Southwest Airlines jetliner carrying 142 people diverted to Los Angeles last night because of a burning electrical smell in the passenger cabin.
 
The diversion came two days after another Southwest aircraft, a Boeing 737-300, made an emergency landing in Arizona after a hole was torn in the passenger cabin ceiling. No one was seriously hurt.
