Update on Part 23 Jet & CS-23 High Performance Aeroplane Issues

  • Aircraft Certification Workshop


Issues

  • Scope Differences

  • Generic VIs & Standard Differences

  • Current Projects

  • Suspended Projects



Scope Differences

  • FAA has found that Title 14 Code of Federal Regulations (14 CFR) part 23 does not contain adequate or appropriate safety standards for jet airplanes.

  • EASA has found that Certification Specification CS-23 does not contain adequate or appropriate safety standards for high performance aeroplanes



Scope Differences

  • FAA is applying part 23 jet policy.

    • Single-engine Normal, Utility and Acrobatic Category
    • Multi-engine Normal, Utility and Acrobatic Category
      • 6000 lbs or less
      • 9 passengers or less
    • Multi-engine Normal, Utility and Acrobatic Category
      • 12500 lbs or less but greater than 6000 lbs
      • 9 passengers or less
    • Multi-engine Commuter Category
      • 19000 lbs or less
      • 19 passengers of less


Scope Differences

  • EASA is developing a “Basic Set of CRIs”, also including (generic) CRIs applying to CS-23 high performance airplanes (HPA)

    • MD ≥ Mach 0.6
    • Service ceiling > 25,000 ft
  • EASA generic CRIs are not limited to jets.

  • Out of the “Basic Set of CRIs” CRIs will only be applied as required depending on specific design of the airplane.



Generic VIs & Standards Differences

  • FAA Generic VIs & Standard Differences

    • 12 generic VIs corresponding to 11 significant standard differences and one different acceptable means of compliance.
    • 3 Non-significant standard differences.
    • Developed and first published on FAA website in April 2005 time frame.


Generic VIs & Standards Differences

  • FAA has developed an unofficial part 23 jet guide to help ACOs in type certification

    • Based on experience of certificating small jets since 1958.
    • Core requirements for jets goes back 30+ years.
    • We are now at 39 pages of special conditions for Normal category multi-engine jets
      • 12500 lbs or less but greater than 6000 lbs
      • 9 passengers or less


Generic VIs & Standards Differences

  • EASA is in the process of developing these lists.

  • Basic Set of CRIs”, Current status:

    • 19 Generic CRIs calling up Special Conditions are released
    • 7 CRIs calling up AMC / GM for HPA are released
    • 14 Generic CRIs calling up Special Conditions are under discussion (of which 11 are the split up of the typical single CRI for Flight Items)
    • 2 CRIs calling up AMC / GM for HPA are under discussion.
    • 27 Standard CRIs applied based on new technology to all CS-23 airplanes (HIRF, Software, etc.)
  • Note: Only a limited number of CRIs will be applied as required depending on specific design of airplane



Part 23 Jet Project Status

  • The FAA has 11 open certification projects for light jets

  • The designs range from an under 6,000-pound, single-engine jet to twin engine, commuter category jets.

  • Other manufacturers are developing jet designs and depending on viability, there may be as many as eighteen additional light jet type certification projects.

  • Many of the US based firms are, or will be, seeking EASA validation.



Part 23 Jet Project Status

  • Six US based firms have applied for EASA validation.

  • The current or anticipated FAA/EASA validation projects are:

    • Cessna Aircraft Company—Citation CitationJet CJ4.
    • Eclipse Aircraft—Model 500.
    • Honda—HondaJet.
  • Projects that have suspended EASA validation efforts:

    • Aviation Technology Group—Model 100 (Javelin).
    • Adam Aircraft—Model 700.
    • Spectrum Aeronautical—Model 33 and Model 40.


CS-23 HPA Project Status

  • EASA has one commuter category jet from an which is seeking FAA validation.

    • Grob Aerospace—G180A, (Germany).
