Response to requests for a comment period extension.


The FAA published a Notice of Proposed Rulemaking (NPRM) on September 14, 2010, to amend its existing flight, duty and rest regulations applicable to certificate holders and their flightcrew members. The FAA has received several requests from stakeholders to extend the comment period for filing comments to the proposed rule. This notice provides the FAA's response to those requests.

On September 14, 2010, the FAA published an NPRM (75 FR 55852) entitled “Flightcrew Member Duty and Rest Requirements.” The proposed regulation recognizes the growing similarities between the types of operations and the universality of factors that lead to fatigue in most individuals. Fatigue threatens aviation safety because it increases the risk of pilot error that could lead to an accident. The new requirements, if adopted, would eliminate the current distinctions between domestic, flag and supplemental operations. The proposal provides different requirements based on the time of day, whether an individual is acclimated to a new time zone, and the likelihood of being able to sleep under different circumstances. The NPRM comment period is scheduled to close on November 15, 2010.

Since publication of the NPRM, the FAA has received several petitions to extend the comment period. Requests for extension include those from National Air Carrier Association, Cargo Airline Association (CAA), United Parcel Service (UPS), Atlas Air Worldwide Holdings, Inc., Air Transport Association of America, Inc., (ATA), Air Carrier Association of America, Regional Airline Association, and others. The requests include ones for a 30-day extension, 45-day extension, 60-day extension, and 180-day extension.

In general, the petitioners said the additional time is necessary due to the length and complexity of the NPRM and Regulatory Impact Analysis. Several petitioners, including CAA, UPS, and ATA, also said the recent statutory mandate that requires carriers to submit a Fatigue Risk Management Plan to the FAA by October 30, 2010, will take time and resources away from developing comments to the NPRM.

The FAA has reviewed the requests for an extension of the comment period on the “Flightcrew Member Duty and Rest Requirements” NPRM. While we understand the reasons for these requests, we do not believe an extension is necessary for the reasons stated below.

FAA Response to Comment Period Extension Requests

In 2009, the FAA established the Flight and Duty Time Limitations and Rest Requirements Aviation Rulemaking Committee (ARC). The ARC provided a forum for the aviation industry to give extensive input on revising current flight and duty time limitations regulations. Therefore, the FAA does not believe it is necessary to extend the comment period for the proposed rule. Consequently, the requests for an extension of the comment period are denied. Also, in the recently passed Airline Safety and Federal Aviation Administration Extension Act of 2010, Congress mandated that the FAA issue a final rule on pilot fatigue by August 1, 2011. To help ensure that we meet this deadline, the FAA must receive comments to its proposed rule by November 15, 2010. However, as stated in Title 14 Code of Federal Regulations § 11.45, we will consider comments filed late if it is possible to do so without incurring expense or delay.

The requests for extension and this Notice will be included in the rulemaking docket.
