Indonesia's transport ministry will launch an investigation into local carrier Batik Air after both pilots onboard were found to have fallen asleep mid-flight.
The duo – who have both been temporarily suspended – fell asleep for around 28 minutes during a flight from Sulawesi to the capital Jakarta. The Airbus A320 briefly veered off course but was able to land safely.
All 153 passengers and crew members were unharmed. The incident, which happened on 25 January this year, saw the plane on-route to the capital Jakarta from southeast Sulawesi.
The 32-year-old pilot had told his co-pilot to take control of the aircraft about half an hour after take off, saying he needed to rest. The 28-year-old co-pilot agreed, according to a report from the transport ministry. But the co-pilot inadvertently fell asleep as well. According to the report, his wife had just given birth to one-month-old twin babies and he was helping with childcare.
Jakarta air traffic control tried contacting the cockpit of the Batik Air A320 after their last recorded transmission but received no response.
That radio silence lasted 28 minutes until the lead pilot woke up and realised that his co-pilot had also fallen asleep. He also found that the aircraft had briefly veered off course. The pilots then responded to calls from Jakarta and landed the plane safely.
Medical tests before the flight deemed that the duo were fit to fly. Their blood pressure and heart rate were normal and alcohol tests came back negative. But while the pilots appeared to have been fully rested, the tests failed to determine whether the quality of their rest was good, aviation expert Alvin Lie told BBC Indonesian.
Authorities have now “strongly reprimanded” Batik Air over the incident, with Indonesia's head of air transport, M. Kristi Endah Murni, saying that Batik Air should pay more attention to their crew's rest time.
Batik Air has said it “operates with adequate rest policy” and that it was “committed to implement all safety recommendations”. In 2019, the same airline was forced to have an emergency landing after its pilot fainted.
