Sofema Aviation Services (SAS) www.sassofia.com Considers the Aspects of Operational Suitability Data as Related to Certification Specification – Cabin Crew Data (CS-CCD)
Introduction – Part 21 Subpart B Type-Certificates and Restricted Type-Certificates
21A.15 (d) The application for a type-certificate or restricted type-certificate for an aircraft shall include, or be supplemented after the initial application to include operational suitability data, consisting of, as applicable:
- 4. determination of type or variant for cabin crew and type-specific data for cabin crew;
- Note: 21A.15(d)(4) compliance is detailed by the EASA Certification Specifications – Cabin Crew Data (CS-CCD).
Process-wise novelties generated by Part 21 governing the CC Operational Evaluations of A/C:
- Inclusion of the CCD evaluation as part of the Certification Plan
- Establish the Certification Basis for the CCD evaluation:
- CS-CCD, Initial Issue, 31 January 2014 – for CUP + ongoing evaluations;
- CRI – ”Elect to Comply” to CS-CCD – for Grandfathering (GF), or
- CRI – ”Special Conditions”- for GF-ing.
- Support TCH compliance for special instructions to operators, as per Part 21.A.16B-
- ”Special Conditions” (for novel and unusual design features) -e.g. CASE
- Issue OSD-CCD Approval
CS CCD.050 Scope
- These Certification Specifications for Cabin Crew Data (CS-CCD) establish the specifications for the applicant for a type certificate, change approval, or supplemental type certificate to develop and provide:
o Data for the determination process of a new type or variant for cabin crew; and
o Type specific data for cabin crew.
CS CCD.100 Applicability
These Certification Specifications are applicable to:
- Aircraft with a maximum passenger seating configuration capacity of more than 19 seats; and
- Aircraft with a passenger seating capacity of 19 seats or less required to carry cabin crew; and
- Any other aircraft with a maximum passenger seating configuration capacity of 19 seats or less if voluntarily elected by the applicant to facilitate operations with cabin crew.
21A.15(d) 4 Compliance is detailed by the CS-CCD
Cabin Crew Operational Suitability Data- Deliverables deriving from the Scope
CS CCD. 400 – Cabin Aspects of Special Emphasis (CASE) – As a stand-alone document if necessary at the time of the Initial TC, or, included in the Type Specific Data of the respective new type or variant;
CS CCD. 310 – Type Specific Data for the new type or variant;
CS CCD. 215 – Aircraft Difference Table for variant.
Example
A350-900 Aircraft Differences Table (ADT), as per CS CCD.215 Determination of variant
- Determination of “variant” status (where applicable), is required for the TCH demonstration of compliance with Part 21.A.15(d)(4);
- CS CCD.215(b) – “ Existing differences (between the base and the candidate aircraft) and their assessed impact are compiled in the aircraft difference table in accordance with CS CCD.200(b)(1), or using the applicant’s standard form in accordance with CS CCD200(b)(2), to support the development of the differences training by the end user(s)”.
