5. Changes to FAA pilot qualification rules have creat ed an industry-wide pilot shortage which has had an acute impact on Great Lakes. These rule s mandated that prior to employment by a FAR Part 121 air carrier, first officers obtain an Airline Transport Pilo t certification (“ATP”). A key factor to enable a pilo t to receive an ATP certif icate is the accumulation of 1,500 flight hours. While the FAA did provide exemptions for accred ited flight schools to reduce the 1,500 flight hour requirement to 1,250 flight hours for two year accredited programs and 1,000 flight hours for four year accredited programs; the reality th at was not considered by Congress and the FAA is that on average, students graduate from th ese programs with fewer than 300 hours of actual flight time.

Attachment A of this document, illustrates a 52, 212 reduction in certificated pilots from 2009 to 2013 (year ending 2014 data has not yet been made av ailable). This trend is likely to continue and illustrates a clear industry wide problem that has directly affected small community air service. Attachment B, illustrates approximately 2 million fewer domestic departures, or an approximate 20% reduction in domestic departures in the past 10 years. This is another trend that is likely to continue with a contributing factor being fewer p ilots being eligible to enter FAR Part 121 air service in combination w ith mandatory pilot retirements.

In July 2010, the FAA issued a rule that increased the duration of validity for student pilot certificates for pilots

under the age of 40 from 36 to 60 months.
This resulted in the increase in active student pilots to 119,119 from 72,280 at the end of 2009. Instructor 2/
