The backhoes are now digging the land around the wheel, to pave way for the lifting of the Airbus A330-300 aircraft.
The salvage is scheduled to finish within 48 hours, so that the Suvarnabhumi Airport's East runway can reopen on September 11 as planned.
The aircraft skidded off the runway on September 8.
THAI also faces a criticism when its technicians re-painted the logo after the accident.
The airline today issued a statement clarifying that the de-identification of the aircraft in the TG679 incident has long been a practice at the national airline.
It also clarifies that it is not a Star Alliance policy or procedure to de-identify aircraft.
