Iranian investigators have disclosed that the captain of an an ATR 72-500 ignored repeated suggestions from the first officer not to proceed with a landing at Tehran during a storm, before the aircraft sustained damage during the touchdown. The Iran Aseman Airlines aircraft has conducted an unstable approach in the adverse weather, with high levels of acceleration, says the Iranian Civil Aviation Organisation, citing flight-data recorder information. It states that the aircraft, arriving from Rasht on the 11th of June 2018, was travelling at 168kt below 2,000ft despite a limitation of 145kt and, as it passed through 850ft, it was descending at more than 1,000ft/min. The crew received glideslope warnings as well as a ground-proximity warning at 810ft. Upon touchdown the aircraft bounced four times with a maximum impact of over 1.9g. But the inquiry says the captain demonstrated no situational awareness regarding information from other flights and Tehran Mehrabad airport controllers, and relied instead on his visual interpretation of the weather. None of the 68 occupants were injured, however the ATR sustained damage to its nose-wheels, and components including probes, windows, and static dischargers.

Russian authorities have ordered carriers to conduct a one-time inspection of the Sukhoi Superjet 100 fleet, after the fatal Aeroflot accident at Moscow Sheremetyevo last month. Federal air transport regulator, Rosaviatsia says the work must be conducted "within the shortest possible time", and that findings must be directed to the authority's airworthiness management department. The work covers items which includes as a general check of the aircraft's condition, as well as examination of aircraft and engine logs to check performance of maintenance tasks and implementation of service bulletins. Investigators are still investigating the accident that occurred on May 5th in which a Superjet 100 suffered a hard landing, after returning to Sheremetyevo with degraded flight controls, and caught fire. Rosaviatsia says that the deadline for the review certificate is on the 25th of June.

A manufacturing defect will require the replacement of leading edge slat tracks on a small percentage of the global fleet of Boeing 737NG and Max aircraft. Operators operating affected aircraft have 10 days to identify and remove the discrepant parts, and an airworthiness directive will be issued, says the Federal Aviation Administration (FAA).
“Boeing has informed the FAA that certain 737NG and 737 Max leading-edge slat tracks may have been improperly manufactured and may not meet all applicable regulatory requirements for strength and durability,” it says. “The affected parts may be susceptible to premature failure or cracks resulting from the improper manufacturing process. Although a complete failure of a leading-edge slat track would not result in the loss of the aircraft, a risk remains that a failed part could lead to aircraft damage in fight.” The FAA adds that Boeing has identified up to 148 parts produced by an unidentified “sub-tier supplier” as being affected. Globally, the defect affects 133 NG and 179 Max aircraft.
