This advisory circular (AC) provides suggestions to improve sport parachuting safety and disseminates information to assist all parties associated with sport parachuting to be conducted in compliance with Title 14 of the Code of Federal Regulations (14 CFR) part 105. It also contains information for jumpers and riggers on parachuting equipment, on-airport parachuting operations, jump pilot training, aircraft maintenance programs, parachute rigging, and procedures for Federal Aviation Administration (FAA) authorization for flight operations with a removed or modified door.
Guidance for Conduction and Use of Flight Standardization Board Evaluations
a. Evaluating Manufactured or Modified Aircraft. It provides a means but not the only means of evaluating manufactured or modified aircraft by the use of standard systems, processes, and tests necessary to determine pilot training and qualification requirements.
b. Differences in Training and Qualification between Aircraft. It describes an acceptable means, but not the only means, of compliance with applicable Title 14 of the Code of Federal Regulations (14 CFR) that provide for differences in training and qualification between aircraft with the same type certificate. It further describes an acceptable means for providing related aircraft differences training and qualification under provision of 14 CFR part 121 between aircraft with different type certificates that have been "designated" by the Administrator as related. Both of these processes use the provision of the Flight Standardization Board (FSB) report as the basis for the approval of pilot training and qualification necessary for the operation of aircraft. This AC is intended to enhance safety by:
(1) Providing a standard method of assessing applicant programs.
(2) Directly relating pilot training and qualification requirements to fleet characteristics, operating concepts, and pilot assignments.
(3) Permitting better industry planning and management by outlining what FAA requirements apply, what training resources or devices are needed, and what alternatives are possible.
(4) Encouraging aircraft manufacturers to design with the goal of developing common characteristics between related aircraft
(5) Providing a recommended framework for application of suitable credits or constraints to better address new technology and future safety enhancements.

Provision of Technical Assistance to Civil Aviation Authorities for Safety Oversight of International Commercial Air Transportation Including by Commercial Technical Assistance Providers
This advisory circular (AC) provides information about the provision of technical assistance to Civil Aviation Authorities (CAA) related to compliance with International Civil Aviation Organization (ICAO) standards and recommended practices. The AC explains the process the Federal Aviation Administration (FAA) uses to provide assistance to CAAs and also provides guidance CAAs can use to obtain technical assistance from commercial providers if the services of the FAA are not available.
Noncompliance with ICAO standards by CAAs is often identified under the FAA’s International Aviation Safety Assessment (IASA) program. The primary focus for the IASA program is for compliance with ICAO Annex 1, Personnel Licensing; Annex 6, Operation of Aircraft, Part 1, International Commercial Air Transport-Aeroplanes; and Annex 8, Airworthiness of Aircraft.
This AC contains information a CAA may use to identify:

Certification Data Retention Agreements and Government Records
This advisory circular (AC) describes the procedures that you, domestic design approval applicants and design approval holders (DAHs), should follow when entering into a certification data retention agreement with the Federal Aviation Administration (FAA). This AC also defines the type of certification data that constitute a government record.
If you are planning to use an electronic data storage system as your means of retention for your type design data, we recommend you follow the guidance outlined in AC 21-48, Using Electronic Modeling Systems as Primary Type Design Data. AC 21-48 describes an acceptable means for using electronic modeling systems in design, manufacturing, installation, and inspection processes. Although in that AC we define an “electronic modeling system” as a three-dimensional (3-D) modeling system, we encourage you to use the guidance provided because it identifies the criteria for using electronic type design data and includes requirements for how to access and present the data.
This AC is not mandatory and does not constitute a regulation, but if you elect to follow the means described in this AC, you must follow it in its entirety.
