Sukhoi Civil Aircraft, together with operators, have completed the Sukhoi Superjet 100 fleet inspection. Aircraft which have successfully passed the inspection have resumed flights. The reason for the inspection was the previously detected defect in the stabilizer attachment bands on one aircraft.
As of today, all aircraft have now undergone the inspection, performed by SCA jointly with the airlines operating this type.
Following the results of the inspection, the defect is not of a systemic nature and can be eliminated within a few days. Examination has confirmed that the issue is not a critical situation: the node features a multi-level redundant structure and has a safety margin which is more than twice the operational loads.
SCA has also developed a plan for prompt actions to restore airworthiness and has already commenced its implementation. The replacement of nodes on the aircraft with the defect identified will be completed by late January.
Work will be performed by SCA technical specialists and will also complete a package of works associated with the upgrade of the node in order to avoid the same defect occurs again.
Sukhoi Superjet 100 was designed and tested in accordance with the international and Russian standards of airworthiness, which is confirmed by the type certificate of IAC AR (Interstate Aviation Committee Aviation Register) and EASA (European Aviation Safety Agency).
