Sukhoi has completed repairs on six Interjet Superjet 100s, allowing the aircraft to return to operations.
Five other SSJ100s remain in repair, following a late December grounding of the 11 aircraft due to defects in the stabiliser nodes.
Sukhoi says the repairs were carried out by 22 technical specialists, under the supervision of Mexican aviation authorities.
Interjet operates 21 SSJ100s and has another eight on order, Flight Fleets Analyzer shows.
"SCA strives to provide maintenance support as quickly as possible and is working on improving [the] SSJ100's reliability," says Sukhoi.
Interjet's SSJ100 fleet has accumulated more than 90,000 flight hours over 75,000 flights.
