What happened
An aircraft departing from Minsk Airport for Brest experienced mechanical issues during its cruise at 9,000 feet. The crew observed a rise in oil temperature on the right engine alongside a drop in the second breech temperature. In response to these readings, the captain shut down the right engine and feathered the propeller to proceed toward the destination.
At 14:05LT, the pilot informed Air Traffic Control of the situation and began descending into Brest Airport amidst marginal weather conditions. During the final approach, while the undercarriage and flaps were extended at an altitude of approximately 40 meters, a go-around was instructed. However, the captain continued the approach, leading to the right main gear contacting the runway 390 meters beyond the threshold. The left main gear touched down 73 meters further along the runway. The aircraft traveled 930 meters before overrunning the runway and striking an ILS antenna, which resulted in a post-crash fire that destroyed the plane.
The accident resulted in 21 injuries among the passengers and five serious injuries to the crew members. Tragically, the onboard mechanic passed away from his wounds five hours after the incident.
Findings
A manufacturing defect caused the failure of the second cylinder, necessitating the engine shutdown. The investigation concluded that the captain utilized improper techniques, specifically regarding an incorrect approach configuration on a single engine and a delayed third turn during the final approach. Environmental factors, including limited visibility, a wet runway, and poor weather, also contributed to the accident.
