Eugene L. Vidal for the Bureau of Air Commerce, Memorandum to the Secretary of Commerce (1935)
“ Again, it should be mentioned that last Fall the Bureau reduced the maximum allowable time for first pilots from 1,320 hours yearly to 1,000 hours yearly, and the hours of co-pilots from no limitation to not more than 100 hours per month. From January 1st of this year, the Department policy has been to accept the recommendations of the specialized air line medical examiners for these maximum flight limitations. The pilot of the crashed plane had averaged 83 hours for the three previous months and has no flight duty for some five days prior to this flight. ”
