SUPPLEMENTARY INFORMATION: 

Discussion

    The checklists generated using the information in the proposed AC 
are meant to complement the guidance in the Guides for Certification of 
Part 23 Airplanes (ACs 23-8B, 23-16A, 23-17A, and 23-19) and other more 
project-specific guidance. The material in the proposed AC describes an 
acceptable means, but not the only means, of compliance with 14 CFR 
part 23. The material in the proposed AC is not mandatory or regulatory 
in nature and does not constitute a regulation. Owners/operators of 
part 23 airplanes applying for an STC change covered in this proposed 
AC may use this material as a reference to create a project-specific 
compliance checklist. This material is also intended to be a reference 
for Federal Aviation Administration (FAA) engineers working on STC 
projects for these common changes.
