Carriers from Category 1 countries are permitted to operate into the U.S. and/or codeshare with U.S. air carriers in accordance with Department of Transportation (DOT) authorizations
IASA assessments determine compliance with these international standards by focusing on each critical element (CE) of an effective aviation safety oversight authority specified in ICAO Document 9734, Safety Oversight Manual. These eight critical elements include:
(CE-1) Primary aviation legislation; (CE-2) Specific operating regulations; (CE-3) State civil aviation system and safety oversight functions; (CE-4) Technical personnel qualification and training; (CE-5) Technical guidance, tools and the provision of safety critical information; (CE-6) Licensing, certification, authorization, and approval obligations; (CE-7) Surveillance obligations; and (CE-8) Resolution of safety concerns.
An IASA does not evaluate the safety compliance of any particular air carrier, nor does it address aviation security, airports, or air traffic management.

This fact does not, apparently, take into account that Ethiopia allows 200-hour first officers to occupy the right seat in large commercial aircraft.
In the USA, all our first officers have at least 1,500 hours, by law.
Yes, there may be training issues with this crew, but using copilots with only 200 hours is at least as serious of an obstacle to safety, even with an experienced captain, as in this flight.

You must all take into account that on certain foreign air carriers the local culture is different then what we practice in the USA. The two man USA crew is trained to perform under all flight circumstances with unified, effective, equal, communication between the Captain & First Officer. Of course the Captain retains final control direction...but the crew always operates as a “seamless” team.
In some Asian and African countries the Captain is supreme and the First Officer driven by their culture, will always follow his lead. This situation make for non seamless operations, as such that happened a few years when an Asiana Airlines aircraft crashed while landing in San Francisco, USA.
I am not saying these type actions were present during Indonesian & Ethiopia crashes...but it must be considered, because...the USA airmen have not had a similar incident. In other words, when an abnormal, threatening incident occurs, one crew member continues to fly and control the aircraft while the other crew member addresses the problem. When both crew members become totally immersed in handling the problem a crash is likely to occur.
