Red Wings' two aircraft from Russia were unable to take off from Antalya, Turkey.
The mechanical problems with the Boeing 777s left hundreds of Russian vacationers stuck.
Both flights were scheduled to depart from Turkey's Antalya Airport over the weekend and be operated by Russian low-cost airline Red Wings Airlines, according to The Moscow Times.
Passengers told the regional news outlet E1.ru that the first Boeing 777, which was headed to the city of Yekaterinburg on Saturday, was repeatedly postponed without a reason. Ultimately, the flight was delayed for 48 hours.
The delays left 410 individuals trapped in Turkey for at least two days, according to the prosecutor general's office in the Russian Urals Federal District, where Yekaterinburg is situated.
Uncertainties regarding the plane's mechanical issues remain, but a source in the aviation sector informed E1.ru. that Red Wings had booked too many flights with only three Boeing 777s in its fleet.
On Saturday, the second Boeing 777, which was en route to Zhukovsky airport in the Moscow area, encountered a problem with a damaged cooling system and was forced to land for more than 11 hours.
According to the Telegram messaging service Mash, as a result, three passengers passed out and a fourth had a panic attack. How many passengers were on the trip is unknown.
Red Wings issued a statement stating that "two Boeing 777 aircraft out of the three available in the airline's fleet were simultaneously out of service due to technical reasons," according to The Moscow Times.
Insider's request for response from the corporation was not immediately fulfilled.
The West slapped harsh sanctions against Russia soon after its invasion of Ukraine more than 17 months ago, which had a negative impact on its aviation sector.
This includes blocking allied airspace and prohibiting manufacturers of aircraft, such as Boeing and Airbus, from providing maintenance or delivering spare parts to Russia.
As a result, the Kremlin declared earlier this year that it would authorize "cannibalization," which allows Russian engineers to remove functional components from one jet in order to keep another one flying — albeit doing so frequently takes a lot of time.
Numerous near misses in the aviation sector have already been caused by inadequate aircraft maintenance.
According to a story by the independent Russian news source Arbat, two Aeroflot flights had to make emergency landings in January due to malfunctioning bathroom systems and one month later due to an air conditioning issue.
The largest commercial airline in Russia, Aeroflot, reportedly told its staff in May not to report errors even if they were aware of them, according to the investigative Russian publication Proekt.
According to a former Aeroflot worker who spoke to the media, the directive's major goal is "to prevent aircraft from being grounded due to a malfunction that, on paper, should prevent the aircraft from being operated until it is fixed."
