    Lightbulb SSJ100s Cleared To Resume Flights After Stabilizer Attach Fault Inspections

    ATW Online; Tuesday December 27, 2016
    Russian SSJ100s cleared to resume flights after fault identified
    Sukhoi Civil Aircraft said it has identified a minor fault in the tail stabilizer of one SuperJet SSJ100 during inspections after Russian aviation authorities grounded the aircraft Dec. 24.

    In a statement issued Dec. 27, Sukhoi said there was a “defect in the stabilizer attachment bands on one aircraft” but the fault was not systemic and all other aircraft were able to resume flights after being inspected.

    “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,” Sukhoi said.

    An industry expert said it appeared the “stabilizer attachment bands” referred to in the statement were structural reinforcements in the horizontal stabilizer where it attaches to the fuselage. Sukhoi says it is a redundant structure, which suggests something like a doubler plate added to increase the strength of the joint.

    According to Russian AD 2016-322-02 issued 23-Dec-2016, "During the maintenance of RRJ-95B Aircraft serial No. 95018, tail No. RA-89010, cracks in the lugs of the stabilizer upper and lower bracket attachment bands were detected." The AD required an immediate fleetwide inspection before further flight, then repeat inspections during Daily Inspections. In addition, weekly Eddy Current Inspections are required, with photographic capture.

    Sukhoi Civil Aircraft better start looking for solutions to permanently resolve this defect, probably along the lines of bracket material or design changes.

    No recent experience of Russian aircraft. The days when airport security was not so evident we had a look around an Aeroflot aircraft parked next stand. Impression was it was built like the preverbal brick sh1t house. Main parts of the U/C were roughly machined and every component was BIG. Todays Russian aircraft will need to try to keep weight down so no doubt reduced casting sizes and lighter structure. The old style Russian vodka burners looked like they could survive some very heavy meeting the terrain and some!

    Interjet grounds 11 SSJ100s following inspections
    Mexico’s Interjet has grounded 11 of its 22 Sukhoi Civil Aircraft Superjet 100 (SSJ100) aircraft after conducting inspections on the fleet.

    According to Reuters, Interjet CEO Jose Luis Garza told media in Mexico that “potential anomalies” were found in the 11 aircraft. In a statement on its website, the airline said an airworthiness directive (AD) issued by Russian aviation authorities led to the inspections and subsequent grounding of half its SSJ100 fleet.

    Sukhoi Civil Aircraft said this week it had identified a minor fault in the tail stabilizer of one SSJ100 during inspections. It is unclear whether this is related to the Interjet groundings.

    “With support from [Sukhoi Civil Aircraft] and in line with the regulations of the [Mexican] General Directorate of Civil Aviation, we are working on this situation and reaffirming Interjet’s commitment to meet national and international regulations,” Interjet said in a statement. “We apologize for any inconvenience this may cause.”

    According to Mexico News Daily, Interjet is canceling as many as 25 flights a day because of the grounding. Interjet has ordered 30 SSJ100s in total and is the only operator of the aircraft in the Americas. It has consistently praised the performance of the aircraft since placing it into service in 2013.

    The defect is taking a high hit on this operator. Wonder how Ireland's Cityjet is doing.

    Sukhoi Civil Aircraft repairing grounded Interjet SSJ100s
    Sukhoi Civil Aircraft technical teams have been in Mexico since late December conducting repair work on 11 Superjet 100 (SSJ100) aircraft grounded by Mexican airline Interjet, the only SSJ100 operator in the Americas.

    A Sukhoi Civil Aircraft spokesperson told ATW the aircraft were grounded because of “technical problems with a stabilizer node.” The grounding affected half of Interjet’s fleet of 22 SSJ100s; the airline has eight more SSJ100s on order.

    The repair work is covered under warranty, according to Sukhoi Civil Aircraft, which expects all 11 SSJ100s to be back in service “by the middle of January.”

    Interjet grounded the 11 aircraft following inspections on its SSJ100 fleet prompted by Russian aviation authorities. Sukhoi Civil Aircraft said in December it had identified a minor fault in the tail stabilizer of an SSJ100.

    According to Sukhoi Civil Aircraft, all SSJ100s in operation worldwide have been inspected and were either cleared to continue service or temporarily taken out of service for the necessary repairs.

    The Sukhoi Civil Aircraft spokesperson said Interjet’s SSJ100 stabilizer nodes will be inspected weekly going forward.

    Six Interjet SSJ100s resume flights following inspections
    Russia’s Sukhoi Civil Aircraft (SCA) has completed repairs on six Sukhoi Superjet 100s (SSJ100s) grounded by Mexican airline Interjet, the only SSJ100 operator in the Americas. The aircraft resumed operations in the first week in January, the manufacturer said in a statement.

    “The troubleshooting procedure was agreed with the Russian aviation authorities [Federal Air Transport Agency, Rosaviatsia] and carried out under the control of the Mexican aviation authorities [DGAC],” SCA added. The manufacturer sent 22 technicians to Mexico for the warranty maintenance work at the end of last year. It is expected all grounded aircraft will be back in service by the middle of January.

    Interjet grounded half its 22 SSJ100 fleet at the end of December 2016, after SCA identified a minor fault in the tail stabilizer of one SSJ100 during inspections. “The element [tail stabilizer] has a multi-level redundancy system and was designed with a stability margin far exceeding its service loads. The element was designed and tested in accordance with the Russian and European airworthiness requirements of the IAC AR [Interstate Aviation Committee Aviation Register] type certificate and its validation by EASA [European Aviation Safety Agency],” SCA said.

    Interjet returns 11 SSJ100s into service following repairs.
    Russia’s Sukhoi Civil Aircraft (SCA) has completed repairs on all 11 Sukhoi Superjet 100s (SSJ100s) that were grounded by Mexican airline Interjet, the only SSJ100 operator in the Americas.

    The carrier grounded 11 out of 22 SSJ100s at the end of December 2016 after SCA identified a minor fault in the tail stabilizer of one aircraft during inspections. At the end of last year, SCA experts were sent to Mexico to perform all required maintenance.

    The first six aircraft were returned into service by Jan. 9. The troubleshooting procedure was agreed with Russian aviation authorities and carried out under the control of Mexican aviation authorities.

    “Owing to concerted joint efforts with Interjet’s specialists, within just two weeks all 11 aircraft have been restored and returned to operation,” SCA president Kamil Gaynutdinov said.

    “Thanks to the joint work done with the manufacturer, the process was carried out in a shorter time than initially considered, which will allow Interjet to operate with its entire fleet of 70 aircraft on more than 300 daily flights,” Interjet CEO José Luis Garza said.

    All 11 SSJ100s repaired. Three hearty cheers to Sukhoi Civil Aircraft (SCA), the AOG Team and Interjet’s specialists. Drink up, guys.
