RECOMMENDATION AND DETERMINATION TO SOLICIT FROM ONE SOURCE

OR BRAND NAME

PICK ONE

Sole Source:

I recommend that NASA, NASA Shared Services Center negotiate with only for . The total estimated cost of this effort is and the estimated period of performance or lead-time for delivery is .

OR

Brand Name Justification:

I recommend that NASA, NASA Shared Services Center negotiate with only with vendors who can provide the subject band name from Astronics Advanced Electronic Systems for Single-card 28VDC Electronic Circuit Breaker Units (1448-113), Single-card 115VAC Electronic Circuit Breaker Units (1448- 111), and associated connectors . The total estimated cost of this effort is and the estimated period of performance or lead-time for delivery is 6 months ARO for ECBU’s and 16 weeks ARO for connectors.

This recommendation is for the acquisition of supplies or services determined to be reasonably available from only one source/only one manufacture. Competition is impractical for the following reasons (please answer the questions below):

1. What are the reasons for soliciting only the suggested source/suggested brand name? Please provide the unique characteristics of the items or services along with the supporting rationale and the market research performed to substantiate your reason for the suggested source/brand name.

The Global Hawk project previously purchased like units from Astronics and has spent the last two years evaluating them while developing flight hardware and software in order to integrate them into a single aircraft. During this time, the units have performed as expected and met the requirements such that the project has decided to retrofit its other two aircraft with currently offered enhanced versions of these units. These units have been tested to DO-160 environmental specifications and keep the same functionality that is currently used in the aircraft payload power system. Primarily, this ECB provides aircraft isolated 3-phase controlled AC power, which has been hard to find with other vendors, as well as a built-in feedback/control function that would otherwise have to be implemented separately and add additional cost and engineering to the project.

2. What is the impact to the government if another vendor/brand is used? Include any dollar, schedule, or compatibility impacts if possible.

A rough order of magnitude estimate for evaluating and integrating an alternate brand Electronic Circuit Breaker card is approximately a 1 year effort, including software, electrical, mechanical, structural, and thermal analysis/development/fabrication/testing. Approximate full cost would likely be on the order of
