The federal air transport authority of Russia, Rosaviatsias have stated that the Aeroflot Sukhoi Superjet 100 involved in the landing accident at Moscow Sheremetyevo had suffered a lightning strike at 6,900ft.
The aircraft experienced a “discharge of atmospheric electricity” at 2,100m (6,900ft) after departing Sheremetyevo for Murmansk at 18:02 on the 5th of May. The crew subsequently lost radio communication with Air traffic control and the captain opted to return to the airport, squawking 7600- in line with signaling loss of communication.
Indications showed that the jet landed hard on runway 24L and then bounced several times and a fire erupting at the fourth contact with the runway.

The Federal Aviation Administration has instructed airlines to inspect Boeing 787 ailerons and elevator power control units due to risk that lightning strikes could make the aircraft hard to control. A new airworthiness directive, which takes effect on the 3rd of June, follows “reports of hydraulic leakage caused by damage to aileron and elevator actuators from lighting strikes”. The problems comes in when hydraulic fluid leaks from the power control units at the same time the aircraft loses two hydraulic systems, says the FAA. Such a scenario “could result in an inability to maintain aileron or elevator actuator stiffness and lead to airplane control surface oscillations, which could damage the control surfaces and cause reduced controllability of the airplane”.

13 people, including a family of five lost their lives when a Bombardier Challenger 601 crashed in a remote mountain region in northern Mexico. The wreckage of the small private jet that departed from Las Vegas on Sunday was found via aerial surveillance in the northern municipality of Ocampo, the government of Coahuila state said in a statement on Monday. "There were no survivors seen," the statement said. Mexico's civil aviation authority said the aircraft departed from Las Vegas shortly before 3pm local time (22:00 GMT). Nearly two hours later, Monterrey lost track of the jet and was unable to make contact with pilots, it said in a statement. Mexican broadcaster Televisa said that the pilot had intended to descend to avoid a storm. Francisco Martinez, an emergency services official in Coahuila, told Milenio that recent weather conditions would form part of the investigation into the crash.
