Technical Issues
The crash of a Cuban passenger plane on Friday could have been caused by technical problems, Mikhail Makaruk, a Russian pilot with many years of experience, told Sputnik.
"There are a lot of unforeseen events in aviation. In this case, it seems likely that there was a failure of the material part. The problem could lie in either the engine, or in the control system," the expert said.
Explosion or Sabotage?— Unlikely
Answering the question about whether the technical failure could have been connected with the US embargo on the supply of spare parts to Cuba, Makaruk said that it's unlikely.
"Cubans have a good network of supplies of spare parts. Another thing is that the material part could have worn out. I exclude explosion or sabotage; Cuba has a very good level of control over flight safety," Makaruk stated.
"It is important that the aircraft was old. Although it is reliable as such, metal fatigue could lead to a disaster," the pilot explained.

He also added that Boeing 737 aircraft are very heavy, which limits their ability to maneuver.
Mexican Boeing
A similar opinion has been expressed by Sergey Melnichenko, director general of the consulting and analytical agency "Flight Safety."
According to him, the US embargo on the supply of spare parts to Cuba could not affect the safety of the Cuban aircraft, since it was a Mexican Boeing, which Cuba simply rented.
If the aircraft would have revealed any shortcomings, Mexico could have repaired it without any problems, Melchinko said, adding that if the plane actually took off, then it was considered safe.
A Boeing 737 passenger plane flying to Holguin from Havana crashed on Friday between José Marti International Airport and the town of Santiago de las Vegas with 110 people on board, striking a power line after turning back to the airport.
