The Federal Aviation Administration raised questions in 2010 about whether it should grant a pilot’s license in the United States to Andreas Lubitz, who in March flew a Germanwings jetliner into a French mountainside, but was assured by his doctors in Germany that he had fully recovered from an episode of depression the year before, according to newly released documents.

The release of the information, in response to Freedom of Information Act requests from news organizations, helps to fill in gaps in the timeline of Mr. Lubitz’s illness and treatment, and shows that the authorities in the United States were aware at the time that he had suffered from psychiatric problems.

According to the documents made public by the aviation administration, Mr. Lubitz was treated from January 2009 to that October with at least two drugs, Cipralex and mirtazapine. During that period, he was on leave from Lufthansa’s pilot-training school, a program that normally lasts around two years and included a period of several months at a Lufthansa-owned center in Arizona where he would learn to fly small planes.

Ultimately the agency decided that Mr. Lubitz could travel to the United States and continue his training, but warned him that he would be prohibited from flying if his depression recurred.
