General Aviation, Coded Departure Routes (CDR)
Provides guidance to customers of the National Airspace System on the use of Coded Departure Routes. CDRs provide more flexibility for selecting an alternate departure for specific airport when traffic constraint such as thunderstorms, turbulence, and periods of excessive demand exist. Use of a CDR reduces key-entry inputs for controllers and minimizes read-back time between tower staff and pilots, which creates an abbreviated clearance. These abbreviated clearances provide an efficient means for air traffic control (ATC) to provide alternate routes if an airspace constraint occurs.

Continuing Structural Integrity Program for Airplanes
Provides guidance material to manufacturers and operators of transport category airplanes for use in developing a continuing structural integrity program to ensure safe operation of older airplanes throughout their operational lives. This guidance material applies to large transport airplanes which were certified under the fail-safe and fatigue requirements of Civil Air Regulations (CAR) 4b o 14 CFR part 25 of the Federal Aviation Regulations (FAR), prior to Amendment 25-45, and which have a maximum gross weight greater than 75,000 pounds. Guidance material on this subject for other transports is provided in AC 91-60. The procedures set forth by this AC are applicable to the large transport category airplanes operated under Subpart D of part 91, and parts 121 and 125.

Fatigue Management Programs for Airplanes with Demonstrated Risk of Catastrophic Failure Due to Fatigue
a. This advisory circular (AC) provides guidance on developing and implementing a Fatigue Management Program (FMP). An applicant may develop an FMP as one method to address the unsafe condition that arises when the Federal Aviation Administration (FAA) has determined an airplane type design has an unsafe condition associated with a demonstrated risk of catastrophic failure due to fatigue (hereinafter referred to as demonstrated risk). An FMP incorporates damage-tolerance based inspections or a part replacement/modification program to mitigate the demonstrated risk. An FMP also incorporates inspections based on service history and engineering judgment to address the broader risk posed by potential cracking of other fatigue critical structure in the airplane. The FAA may mandate an FMP by Airworthiness Directive (AD) only in cases in which the FAA has determined that airworthiness action is necessary to address an unsafe condition. The FAA may also approve an FMP as an alternative method of compliance (AMOC) to an AD. b. This AC provides guidance for actions once the FAA determines that an AD is necessary to address the unsafe condition associated with a demonstrated risk. Existing FAA guidance supports development of damage-tolerance based inspection programs for transport category airplanes to look proactively for potential cracks. Such guidance includes AC 91-56B, Continuing Structural Integrity Program for Airplanes, and AC 25.571-1C, Damage Tolerance and Fatigue Evaluation of Structure. These existing ACs do not describe all the actions that should be used to address a demonstrated risk. c. This AC is not mandatory and does not constitute a regulation. It describes an acceptable means, but not the only means, for maintaining the continued operational safety for airplane type designs that have a demonstrated risk. However, if you use the means described in this AC, you must follow it in all important aspects. In this AC, we use terms such as “must” or “require” only in the sense of ensuring applicability of a particular method of compliance when you use a specific acceptable method of compliance described herein. |

Dual J80 Route Procedure
This advisory circular provides information to customers of the National Airspace System (NAS) in regards to the implementation and use of the dual J80 route procedure. The concept of the dual J80 route is to provide a near-term alternative for aircraft that normally file their flight on J80, westbound from New York and Philadelphia area airports. The dual J80 route virtually parallels the current J80 airway. This new procedure will be implemented as an unpublished route available on May 15, 2008. This route will be established and published as a “Q-Route” or Area area Navigation navigation (RNAV) route at a later date. The objective is to provide additional departure capability for westbound aircraft by alleviating constraints associated with airport departure flows that compete for J80, i.e., New York metropolitan and Philadelphia departures, and over flights from points north of the New York area.
Current routes through this airspace transit very busy air traffic sectors, and delays are frequently encountered due tobecause of the large volume of aircraft that use these routes everyday. During summer months, these paths can be constrained by thunderstorms and turbulence. New York area departures will benefit from the additional route and increased flexibility, allowing our customers to receive more efficient air traffic services.
