Proposed Federal Aviation Administration Notice 8150.NTF, Non-Technical Standard Order (TSO) Functions(s) Integrated in a TSO Article

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Notice of availability and requests for public comment.

SUMMARY:

This notice announces the availability of and requests comments on proposedFederal Aviation Administration (FAA) Notice 8150.NTF, Non-TSO Functions(s) Integrated in aTSO Article. The proposed notice will replace FAA Order 8150.1B, Technical Standard OrderProgram, Paragraph 17d(3), dated May 12, 2002. The proposed notice provides guidance toAircraft Certification Field Offices personnel on the appropriate means to evaluate a non-TSOfunction a manufacturer might integrate into a TSO article.

DATES:

Submit comments on or before June 30, 2005.

ADDRESSES:

Send all comments on proposed FAA Notice 8150.NTF to: Federal Aviation Administration, Aircraft Certification Service, Aircraft Engineering Division, Room 815,800 Independence Avenue, SW., Washington, DC 20591. Attn. Mr. Richard Jennings, AIR-130. Or deliver comments to: Federal Aviation Administration, Room 815, 800 Independence Avenue, SW., Washington, DC 20591.

Background

FAA Order 8150.1B, Paragraph 17d(3), as currently written, allows for the incorporationof a non-TSO function in a TSO article, but stipulates the non-TSO safety and performancefunctions be evaluated under the appropriate airworthiness certification procedures during theinstallation process. However, that process permits the design data package granting the "host"TSO authorization to contain the non-TSO function design data package, without assuring therequired performance of the hosting TSO article is unaffected by the added non-TSO function.

Deferring the evaluation of the non-TSO function until installation is not ideal, since theinstaller generally does not have the TSO manufacturer's equipment or expertise available to perform a thorough equipment performance evaluation, especially when the performance mustbe determined by laboratory simulation or under specific test conditions. In the proposed notice,we bring greater scrutiny to integrated non-TSO functions into the host TSO by providingguidance to the Aircraft Certification Office (ACO) for the consistent performance evaluation ofthe non-TSO function at the time of TSO authorization issuance. Note also, as with the TSOarticle itself, the integrated non-TSO function must have separate FAA approval for installationin an aircraft. Thus, this proposed notice allows the ACO to acknowledge the software andhardware design assurance levels and environmental testing accomplished on the non-TSO function, precluding the need for repeated evaluations at each installation approval.
