What happened
On March 8, 2009, an A-36 Bonanza, registration PT-LKH, crashed near Querência, Mato Grosso, during a flight from Aragarças, Goiás, to Fazenda Primavera. The mission was to pick up the aircraft owner and transport them to Cuiabá.
Prior to departure, the owner had contacted the pilot three times to warn of deteriorating weather conditions and suggested delaying the flight until the following morning. Despite these warnings, the pilot proceeded with the flight under Visual Flight Rules (VFR). Approximately 30 minutes from the destination, the aircraft encountered heavy rain and severe meteorological formations. Witnesses at a nearby farm observed the aircraft circling over a landing strip for approximately ten minutes, suggesting the pilot was evaluating whether to land or continue. Shortly after deciding to proceed toward the original destination, the aircraft lost control and struck the ground at a steep 7/5-degree angle. The pilot, the sole occupant, was killed, and the aircraft was destroyed.
The investigation
CENIPA investigators examined the wreckage and interviewed witnesses, including farm employees who observed the aircraft's final maneuvers. The investigation confirmed that the aircraft's maintenance and inspections were up to date, and there was no evidence of engine failure or mechanical malfunction. The impact was characterized by high energy and a concentrated debris field, which is consistent with a loss of control in flight rather than a forced landing due to power loss.
Investigators also analyzed the pilot's psychological profile and experience. The pilot had approximately 300 total flight hours, with only 15 hours in the A-36 Bonanza, and lacked Instrument Flight Rules (IFR) certification. The investigation noted that the pilot's recent hiring and high motivation to complete the mission may have influenced his decision-making.
Findings
- Adverse weather conditions: The presence of heavy clouds, intense rain, and low ceilings made VFR flight impossible.
- Inadequate judgment: The pilot failed to properly assess the risks of continuing the flight despite known deteriorating conditions.
- Improper flight planning: The pilot did not perform an adequate meteorological analysis of the route and chose to depart despite warnings.
- Lack of experience: The pilot's limited flight time and lack of IFR training restricted his ability to maintain situational awareness in marginal weather.
- Psychological factors: Traits of overconfidence and a sense of invulnerability may have compromised the pilot's decision-making process.
