‘The Real World’, not everything works all the time, for every aircraft operator must have some LEGAL way to defer inoperative equipment BEFORE they, fly.

Well …………. They are required
for VFR (night)
BUT not for
VFR (day)
5. Are They Required to be working by an Airworthiness
Directive (AD) or STC
Our research tells us….NO

6. Now you can
Deactivate the NAV Lights IAW
FAR 43.13 & 91.213(d), then
Placard it as “INOPERATIVE”
7. Also, the Pilot
or Mechanic MUST Make A Signed Logbook Entry IAW FAR
43.9
Deactivation
The operator must evaluate any proposed deactivation to assure there is no adverse effect that could render another system less than fully capable of its intended function
A certificated pilot can accomplish deactivation involving routine pilot tasks, such as turn off a system, that task must come under the definition of preventive maintenance in FAR Part 43, Appendix A(c)
The The Placard Placard AC91-67AC91-67
AC 91-67, Paragraph 6 ‘Definitions’, page iv, subparagraph (t). “A placard is a decal or label with letters at least 1/8-inch high.”
The operator or mechanic must place the placard on or near inoperative equipment or instruments so that it is visible to the pilot or flight crew and alerts them to the inoperative equipment.

PART 91: General PART 91: General Operating and Flight RulesOperating and Flight Rules
Subpart C: Refers to additional equipment that must be maintained.
Subpart E: Is about maintenance, preventive maintenance, and alterations.
FAR 91 Subpart CFAR 91 Subpart C
References equipment, instruments, & certification requirements. Items that were never part of the aircraft’s original type design
This additional equipment was added to the aircraft
because it either enhances the aircraft’s operating
environment or because it was required by regulation
Some ExamplesSome Examples
ENHANCES the ENVIRONMENT Transponders, Supplemental Oxygen, TCAS, GPS, even Aircraft Lights

mandatory Law requiring…ELT’s

large and turbine aircraft under Section 91.409(e)(f)
FAR 91.405 ( c )FAR 91.405 ( c ) don’t forget (d)don’t forget (d) SHALL have any INOPERATIVE instrument
or item of equipment, permitted to be INOPERATIVE by FAR 91.213 (d)(2) of this part, REPAIRED, REPLACED, REMOVED, or INSPECTED at the NEXT REQUIRED
INSPECTION; AND (d)..When listed discrepancies include
inoperative instruments or equipment, SHALL
ensure that a placard has been installed as required by FAR 43.11 of this chapter
The Big QUESTIONThe Big QUESTION
Whether an item of equipment can go indefinitely in an inoperative status under the rule. IF it meets all of the criteria and is inspected for hazardous conditions at each required inspection, then it can continue to be inoperative. BUT, the intent of the rule is to provide temporary relief until a repair or replacement.
Areas of ConcernAreas of Concern The mechanic can get in trouble, if you do not
inspect each inoperative part under 91.213 (d) in accordance with 91.405 ( c ) at each
100 hour and or Annual inspection. The FAA interprets this as Not Inspecting an
‘alteration’
Areas of ConcernAreas of Concern
If you do not perform or record that you inspected the ‘major alteration’
to the aircraft’s type design you could be
in violation of Sections 91.213 and 43.11 inspections.
