MOSCOW (AFP) -- Russian prosecutors on Tuesday said they would conduct a flight safety inquiry on national carrier Aeroflot following a crash that killed 88 people, the prosecutor general's office said.

Prosecutors will ""carry out checks on the implementation of air safety regulation by Aeroflot"" after a jet belonging to one of the company's subsidiaries crashed on Sunday, the office said in a statement.
The Boeing-737 jet that crashed was operated by Aeroflot-Nord, a company based in the northern city of Arkhangelsk that is 51-percent owned by Aeroflot.
Aeroflot said 21 foreigners were killed, including citizens of France, Germany, Italy, Latvia, Switzerland and Turkey.
The statement said that transport prosecutors would check on compliance with ""flight safety by Aeroflot and its subsidiaries, as well as take measures to prevent breaches threatening air transport safety.""
Prosecutors will carry out similar checks on federal air safety agencies.
In signs of concern about state-owned Aeroflot's reputation, chief executive Valery Okulov said Monday that Aeroflot Nord would change its name and the company announced it would end its code-sharing agreement with the subsidiary.
Russian transport minister Igor Levitin told the Russian news agency Itar-Tass that explosive specialists working at the scene, believed the crash was an accident.
""(They) found no proof whatsoever confirming that it was an attack,"" Levitin said.
The black boxes had been recovered and their analysis -- to establish the cause of the crash -- would take three to four weeks, he added.
However Alexander Bastrykin, the Russian public prosecutor leading the investigation, said preliminary indications suggested the accident could have been caused by ""technical failures.""
He said the airplane crash had been linked to technical failures including a fire in the right-hand engine, he told Itar-Tass.
Aeroflot spokesman Lev Koshlyakov had told journalists earlier Sunday the plane had been given ""a full technical inspection"" early this year and was judged to be in a ""proper condition.""
One witness described seeing the plane pass over his house before watching in horror as it exploded and sent massive chunks of burning wreckage flying to the ground.
""The plane was flying over our building, falling, and it hit the ground about 200 meters (650 feet) away and broke up,"" a local resident, who only gave his name as Maxim, told AFP.
