Installation of Non-Required Equipment

1. Installation of Non-Required Equipment Presented to: AEA Rotorcraft Forum By: Mark Wiley Date: January 24, 2013

2. Outline • What is Non-Required Equipment? • Regulatory Basis • Installation Assessment • Configuration Control • Policy and Guidance

3. What is Non-Required Equipment • Equipment that is not required by • Rotorcraft Airworthiness Rules: Parts 27 and 29 • Operating Rules: Parts 91, 133, or 135, etc. • Has some Declared Intended Use or Function / Mission benefit • Passenger comfort or entertainment • Mission equipment • It does not include enhancements to required equipment

4. Regulatory Basis • Applicable Regulations • Intended Use • 1301 Function • Hazard Assessment • 1309 Failure Conditions • Other airworthiness regulations that apply • 1351, 1357 as an example

5. Regulatory Basis • 1301 (intended use or function) • Applicant is afforded quite a bit of leeway in this area. • Clearly define what the system or equipments intended purpose is. • Or the inverse i.e. what it won’t do or is not intended for use as. • Proposed limitations for the aircraft crew or equipment when it is installed • Loss of function will typically have no safety effect • Address any required training

6. Regulatory Basis • 1309 (Hazard Assessment) • Equipment poses no hazard to the aircraft, crew or passengers • Loss of the equipment/function • Equipment malfunction or failure • Equipment does not pose a hazard to other aircraft or personnel on the ground • Software and complex electronic hardware design assurance • Design assurance levels should be commensurate with the Failure or malfunction hazard classification Not for Loss of Function if there is no safety effect • If a safety effect is identified, appropriate design assurance levels are required

7. Installation Assessment • System safety and environmental assessment • To identify and categorize any potential hazards (based on FHA) • To limit the scope of the certification and determine the extent of environmental, ground and flight testing • Laboratory Qualification • Equipment performance verified in operational environments • Operational limitations and placards may be required

8. Installation Considerations • Does the equipment interface with required equipment? • Where will the equipment be located? • Is the equipment a potential source (e.g. clocked processor, transmitter) of radiated and/or conducted electromagnetic interference? • What is the flammability potential of the equipment? • What are the electrical power requirements for the equipment? • Does the equipment have its own battery?

9. Configuration Control • Need configuration control of COTS equipment for subsequent installations or parts replacement • Provides process for reporting any changes to certified equipment to ensure airworthiness for follow-on installations • Options • Lifetime buy • Type design source control drawing and test procedure • Source control drawing defines critical COTS characteristics (e.g. dimensions, weight, power, battery, case material, performance, electrical or mechanical interface) • COTS critical characteristics conformity inspection • Test procedure • Verify that the COTS meets the critical power, performance and interface requirements • Aircraft installation check • EMC • Aircraft Interfaces

10. Policy and Guidance • AC 20-168, Certification Guidance for Installation of Non-Essential, Non-Required Aircraft Cabin Systems and Equipment • References RTCA/DO-313, Certification Guidance for Installation of Non-Essential, Non-Required Aircraft Cabin Systems and Equipment • AC 20-177, Design and Installation Guidance for an Airborne System for Non-Required Telecommunications Service in Non-Aeronautical Frequency Bands • AC 27-1B, Certification of Normal Category Rotorcraft • AC 29-2C, Certification of Transport Category Rotorcraft
