The owner of any Part 23 aircraft, or heritage Part 23 aircraft (CAR3 etc) regardless of weight, number of engines or
horsepower may elect to redesignate his or her aircraft as a Non-Commercial (TC).
Privileges
- Aircraft in this category can be maintained by the owner using the same procedures that have been established for
Experimental AB aircraft.
- Replacement or Alteration Parts should be appropriate for aircraft use, however need not be PMA / TSO authorized.
- Owners can “opt out” of Airworthiness Directives at their discretion.
- Owners can alter their own aircraft without the requirement for a Field Approval or STC. (however, some alterations
may require “phase 1” flight testing similar to Experimental AB requirements)
Requirements
- Before conversion, all applicable ADs must be complied with, i.e. it must an airworthy aircraft.
- Airplane owners must affix a “non-commercial” placard readily visible to all passengers
- The aircraft must have a yearly condition inspection by an A&P Mechanic noting the fact that the aircraft is “in
condition for safe operation.” (similar to Experimental AB requirements)
- The above will be codified within Part 23 as a set of “ Operating Rules”
Limitations
- Aircraft can not be used to carry persons for hire, this includes aircraft rental for flight instruction.
- Aircraft owners must maintain a list in the aircraft logbook of ALL applicable ADs and their compliance status. This
list would be used to highlight the owners awareness of the ADs existence and document their choice of whether to
comply or not.
- Aircraft owners must maintain a list in the aircraft logbook of ALL alterations performed that are not FAA approved
and ALL non PMAed / TSO parts installed. This list would be used to facilitate the conversion of the aircraft back to
normal category.
Conversion back to Normal Category
- Aircraft operated in the Non Commercial (TC) class would be dual certificated in both the standard and non
commercial classes, as is common place for Restricted Category aircraft.
- Aircraft in the Non-Commercial (TC) category can be operated in the Standard category, provided the aircraft
reasonably meets it type design data including compliance with all ADs, removal of all Non PMA / TSO parts and
replacement with certified units and the removal of all non-certified alterations
- The conversion can be accomplished by an IA mechanic with a complete and thorough annual inspection and log
book audit. Upon successful completion the aircraft could be operated under it’s Standard Airworthiness Certificate.
The Procedure is very common with Restricted Category aircraft and has proven both safe and successful.
