Prosecutors in Duesseldorf, where Lubitz had an apartment, said the psychotherapy occurred over an extended period before he received his pilot's license, and that medical records referred to "suicidal tendencies."  The country's aviation authority wouldn't comment on Lubitz's health, despite acknowledging last week that his record with the agency noted he needed "specific regular medical examination" beyond the annual checkup required of all pilots.  The head of the German Aviation Medical Practitioners Association, the organization representing doctors who determine if pilots are medically fit to fly, said the standard medical evaluation would not have been able to determine if a pilot suffered from a serious mental illness.  All pilots must undergo regular medical checks that include a cursory psychological evaluation, according to Dr. Hans-Werner Teichmueller, the agency's head.  Workers with backhoes and tractors were laying down a road just over a mile (2 kilometers) long Monday to reach the remote crash site to help speed the investigation.  [...] recovery crews have had to helicopter in and be tethered to local mountaineers to avoid slipping down the rocky, unstable slope.
