Further, it provides information on the types of problems to expect and recommends that pilots perform ongoing preventive maintenance and that mechanics perform maintenance.

In accordance with the current edition of Federal Aviation Administration (FAA) Order 7050.1, Runway Safety Program, the definition of a runway incursion is, any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle, or person on the protected area of a surface designated for the landing and takeoff of aircraft. This AC is intended for use by persons operating aircraft single pilot under Title 14 of the Code of Federal Regulations (14 CFR) parts 91 and 135, and flight schools.

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.

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.

Provides guidance and information to pilots, passengers, and maintenance personnel regarding the crash survivability aspects of small aircraft equipped with shoulder harnesses and the hazards of modifying seats, adding appendages to seats, and storage of articles, beneath the seats.

This advisory circular (AC) provides backgroung information, and describes fractional ownership programs and te application process for obtaining management specifications (MSpecs) to operate under Title 14 of the Code of Federal Regulations (14CFR) part 91 subpart k (part 91K)

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.

This AC was developed in consideration of ENG industry standards and recommended practices.

This AC provides operational guidance to aircraft owners, operators, and pilots operating aircraft under Title 14 of the
Code of Federal Regulations (14 CFR) part 91 who want to replace required paper information and/or utilize hosted database and software applications as part of Electronic Flight Bag (EFB) functionality.

As a result of these updates and consolidating of information, AC 91-74A, Pilot Guide: Flight in Icing Conditions, dated December 31, 2007, and AC 91-51A, Effect of Icing on Aircraft Control and Airplane Deice and Anti-Ice Systems, dated July 19, 1996, are cancelled.

Provides revised information to FAR Part 91 seaplane operators regarding seaplane preflight, oral briefings for seaplane passengers, the use of safety belts and shoulder harnesses in seaplanes, escape/egress after capsizing, water survival, and flotation gear for seaplane occupants.

This advisory circular (AC) prescribes the procedures to develop and submit aircraft owner- and operator-specific inspection programs in accordance with an inspection program selected under the provisions of Title 14 of the Code of Federal Regulations (14 CFR) part 91, § 91.409(f)(4), and satisfies the requirements of § 91.409(g) for review and approval by the Federal Aviation Administration (FAA).

The contents of this document do not have the force and effect of law and are not meant to bind the public in any way, and the document is intended only to provide information to the public regarding existing requirements under the law or agency policies.

This advisory circular (AC) provides information and guidance for lessees and conditional buyers of U.S.-registered aircraft.

56B, Continuing Structural Integrity Program for Airplanes, AC 25.571?1D, Damage Tolerance and Fatigue Evaluation of Structure, and AC 23?13A, Fatigue, Fail-Safe, and Damage-Tolerance Evaluation of Metallic Structure for Normal, Utility, Acrobatic, and Commuter Category Airplanes.

This advisory circular provides guidance to customers of the National Airspace System (NAS) in regard to the use of and participation on ATCSCC hotlines.

This AC provides guidance and standardized methods for meeting the training requirements outlined in Title 14 of the Code of Federal Regulations (14 CFR) Part 91 Subpart N, Mitsubishi MU-2B Series Special Training, Experience, and Operating Requirements, for Mitsubishi MU-2B aircraft.

This AC discusses the potential hazard associated with the sublimation of dry ice aboard aircraft. Precautionary measures and simple rules of thumb are indicated in order to preclude environmentally hazardous conditions affecting crews and passengers aboard aircraft.

The AC describes methods for maintaining aircraft in order to maximize both a safety and economic benefit.

Presents guidelines intended to assist pilots, operators, managers, and other interested persons in the establishment of effective noise reduction procedures when operating helicopters.

Provides guidance for the safe and practical operation of hot air balloons with airborne heaters in compliance with appropriate portions of 14 CFR 91.

This AC excludes airplanes covered by section 91.205(d)(3)(i) and (ii). This AC is applicable to part 23-certificated airplanes (or airplanes certificated under earlier equivalent regulations) that weigh less than 12,500 pounds and are operated under part 91.

Provides information to assist the public in the proper use of child seats aboard aircraft and provides precautions so all occupants are able to exit rapidly from aircraft during emergencies.

Encourages pilots making VFR flights near noise-sensitive areas to fly at altitudes higher than the minimum permitted by regulation and on flight paths, which will reduce aircraft noise in such area.

These departure profiles are consistent with the airworthiness standards required by the Federal Aviation Regulations Part 25 for type certification and Part 91 for general airplane operations.

This AC may also be used as a tool to evaluate the content of an ESTP. This AC is not mandatory and does not constitute a regulation.

If you have such an aircraft, this AC outlines the noise certification requirement dates so you can confirm that your aircraft indeed pre-dates the requirements and should be considered acceptable. We use the term “grandfathered” for these aircraft.
