7. Appendix C, Instructions for continuing airworthiness
The PM1000 is considered an “on-condition” maintenance item. It is checked prior to each flight during
normal operation. There are no additional considerations for continuing airworthiness other than the practices
detailed in AC 43.13-1A, Chapter 15, Paragraph 750. This includes inspecting the unit to be sure it is
securely fastened in its location, and that the wiring harness is not chafed or pinched, and remains secure. All
panel jacks should be checked at each periodic inspection to ensure that they are tight and not in contact with
other items behind the instrument panel.
