FAA Part 21 Certification Procedures for Products and Parts

2019-11-11
Part 21 is the FAA regulation that provides the regulatory framework to conduct certification of products and parts. This includes the engineering, airworthiness, production and quality systems. The aerospace industry is hinged around compliance with Part 21; however, comprehension of Part 21 and its role in civil certification is challenging. This course is designed to provide participants with an understanding of the processes that encompass aircraft certification, including compliance with FARs, certification procedures and post certification responsibilities.

Introduction to Rubber Science and Technology

2019-10-15
Rubber – a loosely cross-linked network of polymer chains that when strained to high levels will forcibly return to at or near it original dimensions. This course is designed to provide the participant with a thorough understanding of rubber’s engineering characteristics. This class will introduce the various sources of rubber, both natural and synthetic. The class will contrast the differences between rubber and plastics; including thermoplastic rubber. Detailed discussions on how to select the correct rubber polymer for the application, highlighting the pros and cons of each major rubber type.

Basics of Silicone Rubber Science and Technology

2019-10-14
Silicone rubber is comprised of inorganic-organic polymers. These materials consist of an inorganic backbone with organic side groups attached to silicon atoms. This family of polymers possesses unmatched versatility giving the formulator and user multiple forms and methods to cross link the polymers into rubber materials having the widest service temperature range of any rubber material. This course is designed to provide the participant with a thorough understanding of silicone’s engineering characteristics.

A Case Study on the Importance of Implementing an Obsolescence Material Management in an Aerospace Manufacturing Supplier Industry Environment

2019-10-11
2019-28-0145
Obsolescence Material management plays an important and vital role in today’s modern Aerospace manufacturing, Aerospace Maintenance, Repair and Overhaul industry as well as Aerospace Distributors. Aerospace vehicles have a considerable longer product life-cycle when compared to any other consumer goods like automobile and electronics industry. With the advent of new, disruptive technologies, many sources and supplies of materials including COTS and Standard catalogue parts, components and goods, which are widely used in an Aerospace manufacturing environment, are diminishing at a considerable rate and thus result in their obsolescence before the end disposal of the product life cycle. It is one of the leading causes to the sale of counterfeit and fraudulent parts and components, which can result in considerable deterioration of Quality and Cost to Customer.

Applying DO-254 for Avionics Hardware Development and Certification

2019-09-26
The avionics hardware industry world-wide is now commonly required to follow DO-254 Design Assurance Guidance for Airborne Electronic Hardware for literally all phases of development: Safety, Requirements, Design, Logic Implementation, V&V, Quality Assurance, etc. The DO-254 standard is a companion to the software DO-178B standard; however, there are many differences between hardware and software which must be understood. This basic course introduces the intent of the DO-254 standard for commercial avionics hardware development.

C919 Trailing Edge Assembly Interchangeable Tooling

2019-09-16
2019-01-1880
Traditional Trailing Edge (TE) assembly that utilise fixtures for accurate positioning of aircraft (a/c) parts do not allow for removal of specific tooling from the fixtures to travel with the TE, post assembly. Instead, the tooling that positions all the primary a/c assembly datums generally utilise precision pins of various sizes that index and clamp the a/c ribs. Often it is difficult to remove the pins post assembly before the spar can be taken out of the fixture. Use of hammers is common place to hit pins out of holes which is less than ideal considering the a/c parts can be fragile and the tooling is precision set. Also, the Main Assembly Fixture (MAJ) that will receive the TE will inevitably need to relocate some if not all the primary a/c ribs and therefore will most likely be subject to some amount of persuasion.
