FAA AC_43-217_Ed_Upd Anticollision Light Maintenance Program

This AC provides guidance in
developing an anticollision light maintenance program. This AC describes an acceptable
means, but not the only means, to comply with Title 14 of the Code of Federal
Regulations (14 CFR). However, if you use the means described in this AC to show
compliance, you must follow it in all important respects.

FAA AC_91-85B_Ed_Upd Authorization of Aircraft and Operators for Flight in Reduced Vertical Separation Minimum (RVSM) Airspace

This advisory circular (AC) provides airworthiness and operational authorization guidance
material for operators, pilots, certificate holders, and/or program managers conducting Title 14
of the Code of Federal Regulations (14 CFR) part 91, §§ 91.180 and 91.706 Reduced Vertical
Separation Minimum (RVSM) operations. RVSM airspace is any airspace or route between
flight level (FL) 290 and FL 410 inclusive where aircraft are separated vertically by 1,000 feet.
This AC has been updated to include guidance on eligibility and compliance for §§ 91.180
and 91.706 RVSM operations when operators seek RVSM authorization under the provisions of
the new Part 91 Appendix G, Section 9, Aircraft Equipped with Automatic Dependent
Surveillance – Broadcast Out.
The Federal Aviation Administration (FAA) intends to transition current authorizations, issued
under part 91 appendix G, section 3, to monitor operations under the provisions of part 91
appendix G, section 9. This action reduces the operator and FAA administrative burdens
associated with maintaining the part 91 appendix G, section 3 authorizations.

FAA AC_120-80B_Ed_Upd Firefighting of General and High-Energy In-Flight Fires

This AC provides information
on the hazards and risks of in-flight fires on transport category aircraft. The information
includes recommended crewmember procedures and training for combating general and
high-energy fires (HEF) caused by lithium batteries. This AC is applicable to operators
conducting operations under Title 14 of the Code of Federal Regulations (14 CFR)
parts 91, 91 subpart K (part 91K), 121, 125, and 135.

TCCA AC 606-001 Flight Simulation Training Device (FSTD) Qualification Requirements for Required Navigation Performance (RNP) Instrument Approach Training

This Advisory Circular (AC) is provided for information and guidance purposes. It describes an example of an acceptable means, but not the only means, of demonstrating compliance with the TP9685 Airplane and Rotorcraft Simulator Manual. It describes the evaluation criteria employed by the NSEP to evaluate whether the replication and presentation of RNP Approaches in an FSTD will sufficiently support TC approved training programs. Should an applicant desire to use another means of compliance, a proposal must be submitted to the Manager, National Simulator Program (MSP) for review and approval prior to implementation. This AC on its own does not change, create, amend or permit deviations from regulatory requirements, nor does it establish minimum standards.

FAA AC_120-113_CHG_1_Ed_Upd_2 Best Practices for Engine Time-In-Service Interval Extensions

This advisory circular (AC) provides information on engine time-in-service
interval extensions. The AC explains the background of engine time-in-service intervals as well
as the Federal Aviation Administration’s (FAA) regulatory requirements for time limitations and
time-in-service intervals for engine overhauls. The AC also provides aircraft operators with
information on the best practices for an engine time-in-service interval extension program and
how to obtain an engine time-in-service interval extension.

This change to the AC removes content referring to
airframe/engine utilization reports, as these reports are no longer required. This change also
clarifies maintenance program instructions and requirements.
