Flight Standards Information Bulletin, FSAW 95-09( )(Amended), titled: “Electronic
Horizontal Situation Indicator (EHSI) Approvals” was originally published for the
purpose of assisting Aviation Safety Inspectors with approval authority and methods for
conducting a field approval for electronic HSI’s. This FSIB describes the qualification of
displays intended for use as essential, not critical, to preclude the need to conducting
additional testing to substantiate immunity to high intensity radiated fields (HIRF)
requirements.
The Environmental Qualification Form for the SN3500 is included in the Appendix, and
should be referenced to the categories appropriate to the aircraft type and environment
into which the SN3500 is to be installed. The environmental category for the SN3500
should be stipulated on the FAA Form 337, or other approval form.
A “Functional Ground Test Procedures/Report” and an “Operational Flight Check
Procedures/Report” is also included in the appendix, and should be used as a basis for
validating the SN3500 equipment configuration and for verifying proper installation and
functional performance. A copy of this form should be submitted along with the FAA
Form 337, or other approval or certification form. A permanent copy must be filed and
maintained by the installing agency. Another copy must be presented to the aircraft
owner for entry into the aircraft maintenance records, as well as a copy forwarded to
Sandel Avionics along with the Warranty Registration Form, Part Number 10129, to be
filed after completion and installation acceptance. If any difficulty is experienced with
the functionality or operational performance of the SN3500, contact Sandel Avionics for
assistance.
