This notice contains guidance that is pertinent to Title 14 of the
Code of Federal Regulations (14 CFR) § 141.63 examining authority qualification requirements.

This notice provides guidance related to the use of a
government-issued driver’s license to satisfy identification requirements when applying for or
exercising the privileges of a certificate, rating, or authorization under Title 14 of the Code of
Federal Regulations (14 CFR) part 61, 63, 65, 67, 107, or 183.

This AC provides information
and recommendations to air carriers operating under the authority of Title 14 of the Code
of Federal Regulations (14 CFR) part 135 and in the noncontiguous States (i.e., Alaska
or Hawaii) on the use of noncertified weather information in support of instrument
approaches conducted under instrument flight rules (IFR) at airports without destination
weather reporting approved by the National Weather Service (NWS) or the Federal
Aviation Administration (FAA).

Aircraft Health Monitoring
(AHM) for maintenance uses onboard sensors, data transmission, and data analysis to
provide information regarding aircraft system performance and structural condition. The
result is then used to make aircraft airworthiness determinations that provide economic
efficiencies while maintaining or enhancing operational safety. This end-to-end process is
known as Integrated Aircraft Health Management (IAHM). This AC provides guidance
for developing an operator’s IAHM program. This AC describes an acceptable means,
but not the only means, to comply with the applicable sections of Title 14 of the Code of
Federal Regulations (14 CFR). However, if you use the means described in this AC to
show compliance, you should follow it in all important respects.

This AC provides instructions
for completing Federal Aviation Administration (FAA) Form 337, Major Repair and
Alteration (Airframe, Powerplant, Propeller, or Appliance).

AC 43.9-1F, Instructions for Completion of FAA
Form 337, dated January 25, 2007, is canceled.

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 updates methods of compliance in response to a safety
recommendation involving an incident on a turboprop powered airplane. More generally, this
advisory circular (AC) provides guidance and describes one method, but not the only method, for
demonstrating compliance with §§ 23.907 (amendment 63 and earlier), 23.2400 (amendment
64), and 25.907 of title 14 of the Code of Federal Regulations (14 CFR) for the evaluation of
vibratory stresses on propellers installed on airplanes. This evaluation uses fatigue and structural
data obtained in accordance with 14 CFR part 35.
