The proposed North American Industry Classification System (NAICS) code for these services is 541712, which falls under exception two in which the small business size standard is 1,250 employees. This RFI is meant to achieve the following goals: 1.) To survey the market place to determine what type of firms are available to do this work. 2.) Determine how the work will be carried out. 3.) To gain feedback from industry on proposed methods for the described work. A. General Description of the Services Requested 1.0 BACKGROUND OF REQUIREMENT: Historically the use of an Arresting Hook assembly has been used on a wide variety of aircraft as a method of effectively controlling a short distance landing under extreme circumstances. The United States (US) Navy relies on the Arresting Gear for all non-Vertical Take-off & Landing (VTOL) Aircraft Carrier based landings. The USAF typically uses the Arresting Hook for emergency situations. The types of uses and types of coatings used for the Arresting Hook assemblies are varied based upon a number of conditions. This includes desired number of uses, cable life, coefficient of friction, corrosion protection, strength and durability, spallation failures and crack propagation. The F-16 Arresting Hook Toe Coating In Accordance With (IAW) MIL-A-18717 has not been improved upon for 50 years. While it was a functional coating in the 1970's, many technological improvements have been made both in coating chemistries and application methods. These improved systems are commercially available and are commonly used in many industrial segments. The original F-16 Toe Coating, that is still used today, consists of a simple oxygen/acetylene combustion powder process using molybdenum material. Commonly referred to as Spray Bond, the 99% molybdenum material provides a fair bond to the Toe Hook substrate, it provides reasonable hardness and some wear protection. In the 1970's it was a good coating for this application however would now be considered a poor choice due to the very low particle velocities, low bond strength, high porosity and oxide content. The methods used to produce this coating is a very old manual spray system per MIL-STD-869 which is heavily dependent upon operator skill. The applied coating is variable from part to part, is subject to cracking during application, and would be considered unreliable by today's standards. As a result, the coatings are likely to fail in use and even if applied correctly would have a relatively short life. Much has changed in Thermal Spray Technology since the 1970's. There are many improved coating chemistries and application methods which have been tested and proven to be extremely effective. High Velocity Oxygen-Fuel (HVOF) systems are the modern standard for thermal spray coating technologies which are known for creating superior coatings via supersonic velocities. The HVOF systems are fully automated with precise control over all operating parameters and application techniques. This creates coatings with extremely high bond strengths, negligible porosity, high density, high hardness, exceptional corrosion resistance, low wear rates and in many cases low coefficients of friction. An application with the appropriately selected HVOF coating would enable the Arresting Hook Toe coating to be vastly improved for an extended life. 1.1 ORGANIZATION BEING SUPPORTED: Air National Guard Utah 2.0.
