Incident Summary
An Azul Linhas Aéreas ATR 72-212A, operating as flight AD-4111, was departing Professor Eriberto Manoel Reino Airport (SBSR) in São José do Rio Preto, Brazil, bound for Viracopos Airport (SBKP) in São Paulo, when the crew received an indication of a malfunction in the left-hand engine (PW127M) during the initial climb.
The flight crew stopped the climb at 5,000 feet and decided to return to São José do Rio Preto as a precaution. The aircraft landed safely back on runway 07 approximately 18 minutes after departure.
Brazil’s CENIPA (Centro de Investigação e Prevenção de Acidentes Aeronáuticos) reported that the crew followed all standard emergency procedures, and the landing occurred without further incident. The aircraft was inspected and returned to service after approximately 32 hours.
Sequence of Events
Pre-incident Conditions:
• The aircraft departed normally from São José do Rio Preto’s runway 07.
• No prior technical issues were reported before takeoff.
In-flight Occurrence:
• During the climb phase, the crew received an engine #1 (left engine) malfunction indication.
• Following standard protocols, they stopped the climb at 5,000 feet and prepared for a return to the departure airport.
Landing & Emergency Response:
• The aircraft landed safely on runway 07 approximately 18 minutes after departure.
• No emergency services intervention was required.
• The aircraft was inspected and cleared for return to service after 32 hours on the ground.
Investigation & Initial Findings
• Brazil’s CENIPA confirmed the occurrence and that the flight crew executed all necessary procedures.
• No additional failures, smoke, or fire were reported.
• Further analysis is likely being conducted to determine whether the malfunction was due to a mechanical failure, sensor issue, or other contributing factors.
Analysis & Safety Recommendations
• Engine malfunctions in twin-engine turboprops require immediate crew action, particularly in critical flight phases like takeoff and climb.
• The PW127M engine has a history of occasional sensor faults, so a thorough inspection of engine monitoring systems is recommended.
• Azul Linhas Aéreas and ATR operators should review engine failure procedures and maintenance protocols to identify any potential recurring issues.
• No regulatory changes are expected unless further investigation reveals a systemic issue with the engine type.
