I'm not sure about the aircraft Bob, but the pilot's training/testing/qualifications are not covered by the US FAA, so all bets are off as to the criteria required for their certification.

In the US, all pilots of any level or rating at a Private Pilot or higher are required to demonstrate proficiency of a prescribed and detailed list of standards. It is called the Practical Test Standards (PTS.) These are prescribed in detail, in an effort to see that all examiners test the same criteria to the same level of proficiency. It's not a perfect system, but it does ensure a certain level of proficiency and experience for each level of certification.

These standards might be lower or higher in other countries.

As far as the aircraft goes, there has been no evidence whatsoever regarding any aircraft malfunctions or shortcomings of any kind in this accident thus far. It doesn't appear that there will be any. Back in the eighties, a fellow went to work for me after Braniff Airways had shut down. He had been an A&P mechanic for Braniff. He had been involved with some contract maintenance for a Mexican airline. We had to do some work in Mexico and he refused to fly whatever airline that was, saying that he had seen how they would not spend money for proper maintenance, and he would not fly on their aircraft. Those aircraft did indeed fly in and out of the US. From that, I ASSUME that aircraft maintained in other countries to different levels are allowed to land in US airports.

Hope this helps.
