Narrative:
The airplane began to have problems with XPDR, which didn´t report to ATC.
ATC called him back to the origin airport. The crew argue that the XPDR was working fine before takeoff and refuses to come back. Six minutes after takeoff the aircraft dissapeared from radar screens somewhere over San Fernando.

Witnesses declared they heard two explosions during afternoon in the region of the Delta (17 kms from San Fernando). The sound would have occurred at the same time of the last cellphone signal was recorded of one occupant.

The accident place was found on August, 19 in the marshy area of the Parana's Delta (S34º1.403′
W58º34.289′).


Conclusions of the Analysis:
On a private general aviation flight, during the climb phase, the aircraft experienced an in-flight loss of control condition (LOC-I) as a result of from which it hit the ground.
The circumstances and conditions present in the accident suggest a situation of high cockpit workload due to the prevailing operating conditions, with the potential to cause loss of flight control. This situation is attributable to the combination of the following factors:
- The particular characteristics of the aircraft;
- The attention required by the transponder as it is not displayed by air traffic control;
- The detour of the planned flight at the request of the inspection department of air traffic;
- Aircraft trajectory management with autopilot switched off;
- The pilot's limited experience in instrument flight conditions.
In addition, the absence of additional instruction in the aircraft type (due to the lack of specific regulations) can be considered a contributing factor, according to the probable scenario described above.
In addition, the research identified the following elements with potential impact in operational safety:
- Absence of the TAWS system on the aircraft in non-conformity with the established RAAC 91;
- Lack of effective means to enable the flight plan office to quickly determine whether an aircraft has operating restrictions;
- Shortcomings in the training of staff in the units ATS and SAR in search and rescue.
