1.0 Introduction

1.1 Objective

The objective of this contract is to obtain materials compatibility laboratory test and evaluation services related technical expertise to assist the FAA Piston Aviation Fuels Initiative (PAFI) and the Eliminate Aviation Gasoline Lead Emissions (EAGLE) programs.

1.2 Background

The Federal Aviation Administration Aviation Research Division is the primary research organization supporting the FAA’s PAFI and EAGLE programs. These programs lead the FAA’s research efforts to identify and authorize unleaded fuel replacements for current 100 octane low lead (100LL) aviation gasoline, the only remaining transportation fuel in the US that contains lead additives. In the 2024 FAA Reauthorization Act, Congress has set a goal for the FAA to transition industry to lead-free aviation fuels for piston-engine aircraft, by the end of 2030, without adversely affecting the safety of the existing fleet. The efforts under this contract are one part of a comprehensive evaluation effort being conducted by the FAA and its Industry partners on unleaded fuel candidates to achieve the agencies’ objectives and Congressional goals.

2.0 Scope

Except as noted under paragraph 9.0 Government Furnished Information, Facilities, and Equipment, the contractor must provide all necessary technical, engineering, operations, administrative, and other support, as well as all facilities, equipment, materials, and supplies required to perform materials compatibility test and evaluation of unleaded candidate fuel in accordance with this Statement of Work and accompanying documents.

Because of the highly sensitive nature of this research, Contractors must be prepared to abide by the specific intellectual property requirements specified herein. Furthermore, the FAA may use the services of other contractors, consultants and/or industry representatives to assist in these efforts.

All personnel involved in supporting or assisting in this effort will be similarly required to abide by the same requirements.

3.0 Requirements

3.1 Program Management

3.1.1 Post-Award Conference.

The Contractor must participate in a virtual post-award conference that will be held within fourteen

(14) calendar days after award. The purpose of the conference is to aid both Contractor and the Government in achieving a clear and mutual understanding of all requirements and to identify and resolve potential issues ahead of time.

The FAA is responsible for establishing the time and place of the conference and will notify the Contractor. The Contracting Officer Representative (COR) will act as the chairperson at the conference or will provide a designee. The chairperson of the conference will be responsible for the conduct of the meeting. A completed Non-Disclosure Form (attached to this SOW) must be provided three (3) business days in advance of the meeting to the Contracting Officer (CO) and Contracting Officers Representative (COR).

Within twenty-eight (28) calendar days after the Post-Award Conference, the Contractor must provide the following items to the FAA COR in writing:

1. List of Contractor Points of Contact, including contact email, role, mailing address, and phone numbers.

2. Proposed schedule of the Test Activities (see paragraph 4.5). Contractor must prioritize completion of the MTP-002 Table D-1 Polysulfide Sealant testing (not the Table D-2 Polysulfide Sealant Validation List) in its planning and test conduct efforts.

3. Shipping address(es), phone number, and contact information for fuel deliveries and the government furnished property referenced in paragraph 11.0 Shipping.

3.1.2 Status Meetings/Teleconferences.

The Contractor must participate in one hour or less status videoconferences on a weekly basis, or as otherwise as approved by the COR, to review overall project status including schedule progress, test activities and results, questions and issues arising from the testing, and other information. The FAA COR will coordinate these meetings and act as the meeting Chair. When the FAA COR may be unavailable or directs so, a written summary status report of 1-2 pages in Contractor format that provides the above information, will suffice in lieu of the videoconference. The contractor format will be agreed upon at the beginning of the contract period.

3.2 Technical Tasks

3.3 Fuel Handling Retention and Disposal

The Contractor will use test fuels as specified for the performance of this work, including industry standard 100 octane Low Lead (100LL) and unleaded test fuels. The unleaded fuel(s) will be provided directly by the FAA at no cost to Contractor. Contractor is responsible for obtaining industry standard FBO 100LL avgas, as well as any other test fluids specified to be used in performance of this testing.

Use of fuels during the test program requires bulk handling and storage of experimental fuels. The Contractor will ensure proper handling, storage, and labeling of fuel storage vessels to appropriately segregate test fuel, 100LL, and any reference fuels or fluids during the conduct of testing.

Prior to, during, and after completion of testing, all fuel used in the testing must be retained and properly stored in sealed, stainless-steel, laboratory grade amber glass, or other containers that are approved by the FAA prior to the start of testing. The containers must be properly marked to indicate the specific fuel or fluid and lot or batch number as applicable. If the Contractor plans to reuse any storage containers during testing, Contractor must submit a proposed cleaning protocol to the FAA for review and approval fourteen (14) calendar days for review prior to commencing container cleaning and reuse. The FAA will provide comments and/or suggested changes that must be addressed prior to cleaning and reusing containers.

At the conclusion of testing and at the FAA’s request, any remainder of the unleaded test fuels must be returned to: 1) the FAA WJHTC, 2) the fuel supplier, or 3) disposed of in accordance with all local, state, federal regulations. This includes fuel at sub-contractor or partner locations.

Shipping and/or disposal costs for the unleaded test fuels only, will be reimbursed as an ODC in accordance with the requirements herein. Disposal of unleaded test fuels may only occur with prior written approval by the FAA and proof of disposal must be provided. Contractor will be responsible for disposal of other reference fuels and fluids used in testing once the FAA has accepted that a test is completed per paragraph 4.8 Test Data.

3.4 Sampling and Analysis

The Contractor must collect, package, label, and ship samples as specified, including hazmat packaging and shipping requirements. The Contractor must comply with all local, state, federal regulations covering the shipping of hazardous material.

All analysis of samples will be completed by the FAA at no cost to the Contractor.

The Contractor will be provided a Safety Data Sheet for the unleaded fuel to be tested. The Contractor must not conduct any chemical or physical property analysis of its own on unleaded fuels samples, in accordance with non-disclosure provisions of this contract.
