Safety Investigation Report 2018:2 Analysis/2.3 Medical Human Factors/2.3.2

1) The flight-crew’s medical background and recent activities were examined. All medical files reviewed showed no significant health- related issues. Information derived from interviews with the medical health care professionals in the MAS organisation, members of the family and some friends of the flight crew, and study of the available medical records indicate that the PIC and FO were in good health and certified fit to fly at the time of the flight.

2) The Team noted that the medical records or reports of the flight crew obtained from the MAS Medical Centre facility did not include medical records or reports from other medical facilities. In fact, the Team has found a medical record of the PIC from another private medical centre which was not recorded in the MAS Medical Centre. The records from the MAS Medical Centre as well as the records from private clinics regularly visited by both the flight crew also seemed to be mainly records related to minor ailments such as coughs and colds and may not be reflective of the complete medical record of the individuals in question.

3) Based on the available medical records, only one cabin crew member, the In-Flight Supervisor, was known to have a history of previous seizures in 2013 but was subsequently certified fit to fly. However, all the cabin crew were fit to fly at the time of the flight.
- a) All cabin crew were adequately rested before the flight based on the flying records.
- b) There is no evidence that members of the cabin crew had received any flight training, based on the ‘Basic Flying Training’ and ‘Aircraft Type Conversion Training’ (B777) records of the Company and records of DCA.

4) Both the PIC and FO held valid airman licenses and medical certification. They had received all the required training. It was concluded that both the PIC and FO were properly trained, licensed and qualified to conduct the flight.

5) Based on the flying records from the Scheduling Office, both the PIC and FO were within duty-time limits and therefore were adequately rested before the flight.

6) The interpersonal relationship between the PIC and FO was examined. There were no reports of any conflicts or problems between the PIC and FO prior to the flight or before the day of the flight. This is the first time the PIC and FO have flown together after the latter completed his upgraded training to the B777. The Team did not find any evidence of a strain in the relationship between the two. It was the FO’s last Line Training flight before he was scheduled to be checked out. The FO’s training progress was within the performance of new FOs promoted to the B777 from the smaller fleet.
