About this file

This document is a Source Pre-Qualification Statement for critical helicopter component repair and overhaul, focusing on four specific aviation assemblies: Swashplate and Support Assembly, Scissors and Sleeve Assembly, Tail Rotor Hub Assembly, and Main Rotor Mast Assembly. The document outlines stringent qualification requirements for potential bidders, mandating that companies demonstrate extensive technical capabilities, quality assurance processes, and experience in repairing flight-critical helicopter components. Bidders must provide detailed documentation including factory layouts, machinery lists, quality plans, repair procedures, and evidence of prior successful repairs, with a minimum requirement of performing 75% of repair work in-house.

The qualification process involves a comprehensive review by the Air Force Life Cycle Management Center (AFLCMC/WIUED), with an estimated administrative cost of $6,000 per part for source approval package development. Certain companies are pre-qualified, including Bell Helicopter Textron and Arista, who are automatically waived from first article inspection for specific components. Potential bidders must be ISO 9001:2015 certified, possess experience with similar military or commercial helicopter components, and obtain access to the USAF Technical Order system. The government will conduct an initial review within 45 working days and provide a final source qualification response within 180 days, with the right to witness post-award qualification procedures.

SECTION B: JUSTIFICATION FOR ESTABLISHING A QUALIFICATION REQUIREMENT

The Swashplate and Support Assembly, NSN: 1615-01-018-3484 is a Critical Safety Item assembly that requires overhaul as detailed in the Air Force technical orders. The assembly has special characteristics, which if not conforming to the design of the part could cause failure and ultimately loss of control of the aircraft and result in severe injury or loss of life. The swashplate and support assembly is a device for connecting the rotating, mast-mounted, main rotor control linkage to the nonrotating, fuselage-mounted, cyclic and elevator control systems. The swashplate consists of an outer ring rotating on a ball thrust bearing on a nonrotating inner ring, which is mounted to the support through a gimbal ring to allow tilting any direction. The support also has provisions for mounting the collective lever and sleeve.

The Scissors and Sleeve Assembly, NSN: 1615-00-204-6973 is a flight safety critical part. The assembly has special characteristics, which if not conforming to the design of the part could cause failure and ultimately loss of control of the aircraft and result in severe injury or loss of life. It consists of two scissor levers and a rotating hub splined to the mast and mounted through ball thrust bearings on the upper end of the non-rotating collective sleeve. The collective sleeve is operated between the swash- plate support and mast and is actuated by collective levers attached to the lower end. The outboard ends of the scissors are connected to the swashplate outer ring by two drive links. The inboard ends of the scissors are indirectly connected to the pitch horns by two control tubes which transmit collective and cyclic control motions to the mixing levers in the stabilizer bar.

The Tail Rotor Hub Assembly, NSN: 1615-00-254-2174 is a Critical Safety Item assembly that requires overhaul as detailed in the Air Force technical orders. The assembly has special characteristics, which if not conforming to the design of the part could cause failure and ultimately loss of control of the aircraft and result in severe injury or loss of life. The tail rotor hub-assembly employs a pre-coned, flex beam type yoke, Teflon lined pitch change bearings for blade installation and a two-piece delta hinged trunnion.

The Main Rotor Mast Assembly, NSN: 1615-00-255-2896 is a Bell Helicopter-designated Flight Safety Part and a Safety Critical Screw Threaded Component (SCSTC). SCSTCs are threaded components which, if they suffer a thread or material related failure in isolation, may result in the loss of aircraft, loss of life, or severe injury. The critical performance requirements of the mast assembly are the condition and integrity of the threads, proper fastener installation and torquing of nuts, and correct bearing installation. The Main Rotor Mast Assembly provides a means of mounting the main rotor and connecting it to the transmission. The mast is a tubular steel shaft fitted with two bearings which support it vertically in the transmission. Mast driving splines engage with the transmission upper stage planetary gear, providing counterclockwise rotation as viewed from above. Splines on the upper portion of the mast provide mounting for the main rotor and control assemblies.

SECTION D: ESTIMATE OF THE TEST AND EVALUATION COSTS

This cost estimate is required per FAR 9.2029(a)(1)(ii) and 10 U.S.C. 2319(b)(3). It is intended to identify the costs for test and evaluation which will likely be incurred by the potential offeror to become qualified to repair and/or overhaul each part associated with the requirements being sought via the above PR. The total below pertains to only a single part; therefore, this should be multiplied by the number of items a company seeks to qualify. No funds are available to pay for preparation of responses to this announcement

Section Description Est. Cost A Shipping N/A B Dimensional/Electronic Verification

a. Chemical N/A

b. Metallurgical N/A 1.Destructive N/A

2. Non-Destructive N/A

c. Dimensional N/A

d. Electronic N/A

e. Mechanical N/A

f. Non-Destructive Inspection (NDI) N/A

C Nuclear Harness N/A D Form, Fit, Function, and Interface N/A E OEM Qualification Testing

a. Laboratory Costs N/A

b. Flight/Data Reduction & Analysis Costs N/A

F Travel to Contractor or Test Site N/A G SAR Package Development/Evaluation $6,000.00

Total = $ 6,000.00

Comments & Methodology: The above sections are listed in AFMCI 23-113 (Pg 22-23). The Integrated Product Team (to include Engineering) met to evaluate each category and determined that most of these T&E tasks will not be required by AFLCMC/WIUED in order to become considered for qualification. The vast majority of expenses that will be incurred by the Contractor will likely be associated with administrative labor performed to (1) substantiate their Company's technical capabilities and (2) vet that information internally for finalization of their SAR package for submittal to the Government. This is an estimated level of effort for EACH part. The basis of estimate for Section D consists of an approximated 80 man-hours at a rate of $75/hr.
