## 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
- 12500 lbs or less
- 9 passengers or less
- 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 ](http://www.faa.gov/aircraft/air%5Fcert/design%5Fapprovals/small%5Fairplanes/media/SSD%20List%208-3-07.doc)**__**[VIs](http://www.faa.gov/aircraft/air%5Fcert/design%5Fapprovals/small%5Fairplanes/media/SSD%20List%208-3-07.doc)**__**[ & Standard Differences](http://www.faa.gov/aircraft/air%5Fcert/design%5Fapprovals/small%5Fairplanes/media/SSD%20List%208-3-07.doc)**_
- 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**
- 9 currently active
- 2 suspended
**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).
