This specification covers a titanium alloy in the form of bars up through 4.000 inches (101.60 mm) in nominal diameter or least distance between parallel sides, inclusive, forgings of thickness up through 4.000 inches (101.60 mm), inclusive, and stock for forging of any size (See 8.7).
The tow vehicle should be designed for towbarless movement of aircraft on the ground. The design will ensure that the unit will safely secure the aircraft nose landing gear within the coupling system for any operational mode.
This document establishes the minimum curriculum requirements for training, practical assessments, and certifying composite structure repair personnel and metalbond repair personnel. It establishes criteria for the certification of personnel requiring appropriate knowledge of the technical principles underlying the composite structural repairs and/or metalbond they perform. Persons certified under this document may be eligible for licensing/certification/qualification by an appropriate authority, in addition to this industry accepted technician certification. Teaching levels have been assigned to the curriculum to define the knowledge, skills, and abilities graduates will need to make repairs to composite or metalbond structure. Minimum hours of instruction have been provided to ensure adequate coverage of all subject matter including lecture and laboratory.
The purpose of this recommended practice is to provide the aerospace industry with recommendations concerning minimizing of stress-corrosion cracking (SCC) in wrought high-strength aluminum alloy products. The detailed recommendations are based on practical engineering experience and reflect those design practices and fabricating procedures which have been found to be most effective in minimizing stress-corrosion cracking in wrought high-strength aluminum alloy products. This ARP provides general guidelines. For further information see references in 4.3.
This specification covers a copper alloy in the form of wire, rod, sheet, strip, foil, and powder and a viscous mixture (paste) of powder in a suitable binder. This material has been used typically for joining corrosion and heat resistant alloys where high strength, good ductility, and short-time oxidation resistance above 1000 degrees F (538 degrees C) are required, but usage is not limited to such applications. A very good color match is provided for corrosion-resistant steels.
This specification covers a magnesium alloy in the form of sand castings. These castings have been used typically for parts requiring high yield strength up to 570 degrees F (299 degrees C) and excellent corrosion resistance, but usage is not limited to such applications.
