SCAC Completed Stabilizer Elements Repair on SSJ100 Aircraft/02.02.2017

SSJ100 aircraft, with the stabilizer’s issue revealed during an inspection in December 2016, have been repaired by the manufacturer Sukhoi Civil Aircraft Company (SCAC) by February 1, 2017. These aircraft have already resumed flights.

 

The repair was caused by a defect detected in a component of the tail stabilizer as part of a routine inspection. SCAC in coordination with SSJ100 operators conducted the fleet inspection as a result several aircraft required repair which has been successfully completed by now.

 

The research has shown that the defect on several aircraft had been caused by the peculiarities of the elements manufacturing techniques. However the issue is not a critical one in terms of the aircraft operations: the component features a multi-level redundant structure and has a safety margin which is considerably more than the operational loads. Further efforts of SCAC will include improvement of the stabilizer element in order to avoid the same defect occurs again.

 

The Sukhoi Superjet 100 was designed and tested in compliance with international and Russian airworthiness standards and its safety was confirmed by the Type Certificate issued by IAC AR (Interstate Aviation Committee Aviation Register) and validated by EASA (European Aviation Safety Agency) as well.
