Sevenair Accident

Engine problems might have caused the aircraft crash in Ponte de Sor

The crash of an aircraft at the Municipal Airfield of Ponte de Sor (Portalegre), which has resulted in a death of an instructor and a serious injury of his student, may have been caused by "operating problems" of the engine.

In an informative note from the Office for the Prevention and Investigation of Aircraft Accidents and Railway Accidents (GPIAAF) published on Monday, the body states that the Reims Cessna F150J aircraft belonging to flight school of Sevenair took off from the airfield at 2:00 p.m. for an instructional flight with an instructor and a student pilot on board.

The flight, it is indicated, was developed "without any reporting" of anomalies or technical difficulties.
"After returning to the airfield, at 3:28 p.m. the second phase of the training planned for the mission was started, with three circuits carried out on service runway 21, without any report of anomalies or technical difficulties," reads the document.
According to the note, at 3:45 p.m., on the ascent line of runway 21, for what would be the last training circuit, the aircraft's engine "evidenced operating problems, recovering soon after for take-off power rotations and, in sequence, will have lost power completely".

The GPIAAF reports that the aircraft, "flying over the threshold of runway 03, banked to the right for a few moments" in a westbound direction, followed by "a turn of 270º" also to the right "on an uncontrolled descent".
"As a result of the loss of control, and without recovering from a pronounced low nose attitude, the aircraft initially collided with the right tip of the wing on the ground, immobilizing a few meters away," it is referred to in the information note.
As "relevant findings", the GPIAAF emphasizes that the crew "was duly authorized and certified" to carry out the flight and that the aircraft "was authorized" to fly in accordance with the regulations in force.
"The crew of the crashed aircraft maintained bilateral communications with the airfield traffic information services and flight information en route, and during the entire flight nothing was reported about any technical problem or limitation of the crew or aircraft," he adds.

GPIAAFBut, the GPIAAF also warns, that "the evidence suggests that the engine was not delivering power at the time of impact with the ground".

GPIAAF also states that, after the conclusion of the investigation, it will publish the final report.

If it is not possible to complete the document "within 12 months", "an interim report will be presented at least on each anniversary date", describing the progress of the investigation and any safety problems encountered, the body adds.

The alert for the crash of the instruction aircraft at the municipal airfield, with two men on board, both Portuguese, was given at 15:49, causing the death of the 36-year-old instructor, and serious injuries to the 19-year-old instructor. The seriously injured was helitransported to the Hospital de São José, in Lisbon.

Without wanting to speculate about possible causes which will be determined in the inquiry, the scenario of a bank to the right followed by a 270 degrees turn, strongly suggests an attempt to head back to the runway.

"the impossible turn" where loss of control is the result of a delayed response due to surprise effect with bank increasing, speed decreasing, a touch of rudder to make things worse almost always leads to an accelerated stall...

However difficult and hard to accept, a short glide ahead and sideways to the left and right to a controlled crash landing while still flying is always better than stalling and having 7-800 kgs dropping from the sky to an unsuvivable impact. This should be drilled and drilled until it becomes second nature RIP

According to the flight radar, they were practicing circuits using runway 21 but it seems that the engine cut off over the threshold of 03. Their altitude was already low and just like you mentioned, I think the instructor went for the impossible turn. Hard to speculate but very sad event indeed.

Hopefully the investigators will publish the results of their examination of the engine, if it survived the crash.
