This advisory circular (AC) provides guidance to those persons applying for a Flight
Standardization Board (FSB) to have new or modified aircraft types and models evaluated for the
purpose of determining minimum flightcrew training, checking, and currency recommendations;
determining and establishing pilot type ratings; developing recommended aircraft type-specific
training; and determining the scope of differences training and related aircraft differences
training. This AC applies to aircraft manufacturers, type certificate (TC) holders, and aircraft
modifiers seeking to use the FSB process.
Use of this AC enhances the safety of flight operations by providing a standard method of
relating pilot training and qualification requirements to fleet characteristics, operating concepts,
and pilot assignments; providing a consistent standard for determining necessary training
resources or devices; encouraging aircraft manufacturers to design with the goal of developing
common characteristics between related aircraft; and providing a recommended framework for
application of suitable credits or constraints to address new technology and future safety
enhancements.
This revision reformats the AC and replaces the appendices with chapters; adds new and revised
definitions and acronyms; clarifies Aircraft Evaluation Division (AED) responsibilities;
incorporates human factors (HF) considerations; revises references; clarifies pilot training,
qualification, and type rating evaluation; updates rating and level tests planning and proposals;
and removes operator Differences Tables (DT) and related principal inspector responsibilities.

This technical standard order (TSO) is for manufacturers applying for a TSO
authorization (TSOA) or letter of TSO design approval (LODA). In this TSO, the Federal
Aviation Administration (FAA) describes the minimum performance standards (MPS) non-
rechargeable lithium cells and batteries must meet for approval and identification with the
applicable TSO marking.

This notice announces new and revised operations specifications
(OpSpecs) and training specifications (TSpecs) applicable to powered-lift operations conducted
in accordance with Title 14 of the Code of Federal Regulations (14 CFR) parts 135, 142,
and 194. These authorizing documents will enable certificate holders (CH) utilizing powered-lift
to conduct pilot training and operations.

This change transmits revised pages to Order 8150.1D, Technical Standard
Order Program.

This order provides the minimum requirements that must be included in any new or
revised TSO. This information was previously contained in appendix G of FAA Order 8150.1D,
Technical Standard Order Program. The template contained herein is unchanged from the one
previously found in Order 8150.1D.

This advisory circular (AC) provides guidance and information for compliance with the
provisions under title 14, Code of Federal Regulations (14 CFR), part 33 on the materials
suitability and durability requirements of § 33.15, as applicable to the manufacture of titanium
alloy high energy rotating parts of aircraft engines.
