About this file
This is a Test and Evaluation Plan for a First Article aircraft tow tractor being procured by the United States Coast Guard (USCG) under contract 70Z03826QE0000026. The plan outlines comprehensive testing procedures that will be conducted by the USCG Aviation Logistics Center's Aviation Ground Support Equipment team and Engineering Specialists to verify the vehicle meets all solicitation requirements before production units are accepted.
The test plan is organized into four primary sections covering dimensional and weight verification, functional and performance tests, operator cabin features with lights and safety systems, and documentation verification. Dimensional requirements include maximum length of 150 inches without hitches and 180 inches with hitches, maximum height of 8 feet, maximum width of 90 inches, and minimum gross weight of 17,000 lbs. The tractor must be white with ATA airport markings and reflective materials, and feature 2.75-inch hitch pin diameters. Functional testing verifies draw bar pull of at least 14,000 lbs, transmission with 2 forward and 1 reverse gear, 4-wheel drive with 4-wheel hydrostatic steering, dual braking circuits with hydraulic release parking brake, front and rear inching controls, and an 80-volt battery system with minimum 66 kWh capacity and onboard charger. Operator cabin requirements include mirrors with visibility of both hitches, climate control with defrost/AC/heat/fan, front and rear wipers, suspended driver seat with two passenger seats, beacon and work lights, reverse buzzer and horn alarms, weatherproof backup camera, and a 20-pound mounted fire extinguisher. The vendor must provide one complete hardcopy operations manual and PDF versions of operations, maintenance, and parts manuals. The First Article unit must pass 100% of all tests to receive approval; any failure results in rejection and requires the vendor to correct deficiencies and resubmit at the vendor's expense, with the USCG ALC AGSE team holding final approval authority.

Aircraft Tow Tractor Test and Evaluation Plan
70Z03826QE0000026
Attachment 4
1.0 Introduction
This document outlines the test and evaluation (T&E) plan for the First Article of the conventional aircraft tow tractor, as solicited by the United States Coast Guard (USCG).
The purpose of this T&E is to verify that the vehicle meets all salient characteristics and performance requirements outlined in the solicitation before production units are accepted. Testing will be performed by the USCG Aviation Logistics Center’s (ALC) Aviation Ground Support Equipment (AGSE) team and Engineering Specialists.
2.0 Scope
This plan covers the verification of the tractor's physical dimensions, weight, performance, operator cabin features, safety systems, and required documentation. Each characteristic listed in the solicitation will be tested and evaluated against the specified requirements.
3.0 Test Procedures
The following tests will be performed on the First Article unit.
3.1 Dimensional and Weight Verification
The vehicle will be measured and weighed using certified scales and measurement tools to ensure it conforms to the physical requirements.
Characteristic Requirement Test Method Pass/Fail Criteria
Length (w/o hitches)
≤ 150 inches Measure with a calibrated tape measure from the furthest points of the main body, excluding hitches.
Must be within the specified maximum length.
Length (w/ hitches) ≤ 180 inches Measure with a calibrated tape measure from the furthest points, including hitches.
Must be within the specified maximum length.
Overall Height ≤ 8 feet Measure from the ground to the highest point of the cab (including beacon).
Must be within the specified maximum height.
Overall Width ≤ 90 inches Measure at the widest point of the vehicle.
Must be within the specified maximum width.
Gross Weight ≥ 17,000 lbs Weigh the vehicle on a certified vehicle scale.
Must meet or exceed the minimum weight.
Attachment 4 Chassis Color White Visually inspect the vehicle's paint color.
Color must be white.
Markings ATA airport markings, reflective
Visually inspect for correct markings on all sides. Test reflectivity in low light.
Markings must be present, correct, and reflective.
Hitch Pin Diameter 2.75 inches Measure the pin diameter of the front and rear hitches using calipers.
Diameter must match the requirement.
3.2 Functional and Performance Tests
These tests will verify the operational and performance capabilities of the tractor.
Characteristic Requirement Test Method Pass/Fail Criteria
Draw Bar Pull
(DBP)
≥ 14,000 lbs Perform a DBP test using a calibrated load cell or dynamometer.
Achieves a sustained pull of at least 14,000 lbs.
Transmission 2 forward, 1 reverse Operate the vehicle through all gears (R, N, D1, D2).
All gears must engage and function correctly.
Drive and Steering 4-wheel drive, 4-wheel hydrostatic steering
Drive the vehicle on various surfaces and execute turns.
4WD engages and steering is responsive and functional.
Brakes Dual braking circuit, hydraulic release parking brake
Perform service brake tests and verify the parking brake holds the vehicle on an incline.
Brakes must function effectively; parking brake must hold and release correctly.
Inching Controls Front and rear controls
Test the inching controls at both the front and rear of the vehicle.
Vehicle must move in small, controlled increments as commanded.
Battery and Charging
80v system, ≥ 66KWh, onboard charger
Inspect battery specifications. Connect the charger to 240V/480V 3-phase power.
Battery meets specs; charging system initiates and functions correctly with Posi Charge inlet.
Attachment 4
