1.      The pilot did not follow the Standard Operation Procedures (SOP) set by the Flight Operating Manual (FOM) for a stabilized approach, nor for an emergency call (Call Out Procedure), or for a new flight operation (Go Around Procedure) when the aircraft was in crisis.

2.      No one pressed the TO / GA switch which allows the aircraft to increase the speed and the
height of its flight. No one monitored (Monitoring) changes to the throttle during the crisis.

3.      Coordination in the cockpit (Crew Co-ordination) was ineffective. The workload of the pilots was too large.

4.      The weather changed rapidly in the vicinity of the airport.

5.      Pilots have accumulated stress (Accumulation of Stress) and fatigue (Fatigue). They had little rest which accentuated the fatigue.

6.      Control of the aircraft was moved from pilot to pilot during the crisis at the moment of the new (approach?).

[1] This is the 2nd time Ive heard senior Thai government officials misunderstanding the relationship between FAA & NTSB.

[2] No mention of the US. This is probably accurate; weve received no governmental support or information once my brothers body was returned.

[3]Udom, they wrote a special action just for you. Dont forget, you are responsible for ALL the actions by the airline, past, present and future.

[5] Gee, thats worrisome considering the incentives Orient Thai has given in the past.
