Airworthiness
Airworthiness approval of the JA40-001 may require completion of a TCCA Major Modification Report per CAR
STD (AWM) 571 Appendix L, or a FAA Form 337. The sample wording for a description of the work is provided to
assist the Installing Agency in preparing Instructions for Continued Airworthiness (ICA) when replacing an existing
Isolation Transformer with a Jupiter Avionics JA40-001 ICS Tie Line Isolation Transformer. This sample may be
modified appropriately for new installations. It is the installer’s responsibility to determine the applicability of the
method used. Installations performed outside Canada must follow the applicable aviation authority’s regulations.
Sample Wording:
Removed the existing [model] Isolation Transformer and replaced with a Jupiter Avionics JA40-001 ICS Tie Line
Isolation Transformer in [aircraft location].
Installed in accordance with the JA40-001 Installation Manual, Revision [ ], and AC 43.13-2, Chapters 2, and 3.
The JA40-001 interfaces with existing aircraft systems per the Installation Manual instructions.
The JA40-001 Installation Manual provides detailed installation instructions and wiring diagrams (Section 2, and
Appendices A and B).
The JA40-001 does not require electrical power.
Aircraft equipment list, weights and balance amended. Compass compensation checked and found to conform to
applicable regulations.

Instructions for Continued Airworthiness
Maintenance of the JA40-001 ICS Tie Line Isolation Transformer is “on condition” only. Refer to the JA40-001
Maintenance Manual. Periodic maintenance of the JA40-001 is not required.
The following sample Instructions for Continued Airworthiness (ICA) provides assistance in preparing ICA for the
Jupiter Avionics JA40-001 unit installation as part of a Type Certificate (TC) or Supplemental Type Certificate
(STC) project to comply with CAR STD (AWM) 523/527/525/529.1529 or FAR 23/25/27/29.1529 “Instructions for
Continued Airworthiness”.
Items that may vary by aircraft make and model are shown in brackets (“[ ]”) and should be filled in as
appropriate. Some of the checklist items do not apply, in which case they should be marked “N/A” (Not
Applicable).
