The Future ofDesign Organisation Approval
  • A perspective from the smallest design
    organisations
  • by
  • Werner Scholz, Spokesman of the
  • European Sailplane Manufacturers

Contents
  • Introduction
  • Who are we - whom do we represent?
  • National rules - JAR - EASA
  • DOA in the past - what is the history?
  • Status quo
  • How works sailplane development today?
  • Future of DOA
  • What is needed for light aviation?

3
IntroductionWho are we - whom do we represent?
  • The European sailplane manufacturers are
    represented by two associations
  • Verband deutscher Segelflugzeughersteller
  • European Glider Manufacturers and Suppliers
    association
  • Together they include 13 companies in
  • Austria, Czech Republic, Germany, Lithuania,
    Slovenia
  • with together more than 1000 employees.

4
IntroductionWho are we - whom do we represent?
  • Further members of the sailplane industry
  • Additional European sailplane manufacturers not
    represented by the two associations
  • Manufacturers of glider-typical avionics
  • Manufacturers of trailers and equipment
  • Glider maintenance facilities

5
IntroductionWho are we - whom do we represent?
  • Together the European sailplane industry
    represents
  • more than 20 sailplane manufacturers
  • more than 30 manufacturers of gliding equipment
  • more than 90 of world-wide sailplane
    production(over 400 new aircraft per year)
  • more than 3000 employees at the manufacturers and
    associated companies

6
IntroductionWho are we - whom do we represent?
  • The gliding community in Europe includes
  • over registered 20.000 sailplanes
  • over 70.000 pilots flying gliders and powered
    sailplanes
  • a starting point towards a professional career in
    aviation for several 100.000 people since more
    than 50 years
  • close ties to other light aviation communities
    like hang-gliding, paragliding and microlights

7
National rules - JAR - EASA DOA in the past -
what is the history?
  • On the national level before implementation of
    JAR 21 sailplane manufacturers mostly were
    already approved Design Organisations.
  • the national DOA included all privileges as the
    current Part 21 Subpart J DOA
  • design organisation manuals were in the national
    language
  • manuals covered mostly procedures between DOA and
    NAA and internal procedures were kept minimal

8
National rules - JAR - EASA DOA in the past -
what is the history?
  • DOA on the national level
  • issuance of TC and of DOA at the NAA often by the
    same departments and/or persons with a personal
    background in gliding / light aviation
  • certification verification was done at the DOA
    level, sometimes with the NAA authorities
    checked technical content of the TC
  • type certification as teamwork between
    manufacturer and NAA with technical expertise on
    both sides

9
National rules - JAR - EASA DOA in the past -
what is the history?
  • Introduction of JAR 21 - DOA on an European
    level
  • new possibility within JAR 21 to obtain DOA for
    simple designs (JAR 21.13b) with alternative
    procedures
  • under this regulation most national DOA with full
    privileges became semi-national DOA according
    to JAR 21.13b with limited privileges
  • DOA approval was issued by NAA but often now by
    DOA specialists without detailed knowledge of
    small manufacturers

10
National rules - JAR - EASA DOA in the past -
what is the history?
  • Introduction of JAR 21 - DOA on an European
    level
  • design organisation manuals were mostly still in
    the national language
  • the much advertised European certification turned
    out to be non-feasible due to exaggerated fees of
    NAAs (invoices even from states where no gliders
    were sold!)and because of participating NAA
    without detailed experience in sailplane
    certification

11
National rules - JAR - EASA DOA in the past -
what is the history?
  • Introduction of JAR 21 - DOA on an European
    level
  • the switch from the national DOA to the simple
    design DOA according to JAR 21.13b did cost on
    averageA) about 1 to 2 man-years per company
    for introduction of new manuals and
    proceduresB) about 10.000 to 20.000 per
    company for certification of the new
    manualsC) about 1 to 2 man-months per company
    within the NAA to issue the new DOAs

12
National rules - JAR - EASA DOA in the past -
what is the history?
  • Introduction of JAR 21 - DOA on an European
    level
  • total sum of costs by the switch national to
    JAR21for all European sailplane manufacturers
    togetherapprox. 1 Mio. for all NAA together
    approx. several 100.000
  • BUT The way sailplanes are designed stayed the
    same, only the privileges of the organizations
    were reduced...

13
National rules - JAR - EASA DOA in the past -
what is the history?
  • Introduction of Part 21 - EASA issues European
    DOA
  • the JAR 22.13b simple design DOA were not granted
    grandfather rights due to the limited
    privileges
  • due to the limited workforce at EASA a fast and
    easy way to work under Part 21 was offered by
    EASA NAADesign Organisations working under
    Alternative Procedures (ADOAP)
  • full Subpart J DOA seemed unobtainable due to
    long delays in the approval process and
    complicated rules

14
National rules - JAR - EASA DOA in the past -
what is the history?
  • Introduction of Part 21 - EASA issues European
    DOA
  • the result most manufacturers now work under
    ADOAP (with the full scope of work from type
    changes to TC)
  • loss of remaining privileges for the design
    organisations
  • even more bureaucratic effort in the daily work
    as now EASA and NAA are often involved due to
    outsourcing of certification tasks done by EASA

15
National rules - JAR - EASA DOA in the past -
what is the history?
  • Experiences with ADOAP / DOA under Part 21
  • Part 21 is not fully understood by all
    manufacturers
  • new manuals sometimes obligatory in English
    language
  • approval of manuals a lengthy process -
    especially when the EASA specialists (either EASA
    employees or NAA people under task allocation)
    have no experience with small companies and/or
    light aviation

16
National rules - JAR - EASA DOA in the past -
what is the history?
  • Experiences with ADOAP / DOA under Part 21
  • big company DOA complain that DOA privileges do
    not lead to less bureaucratic certification
    proceduresgt therefore no incentive to upgrade
    to DOA
  • ADOAP approvals again caused significant efforts
  • again additional costs and procedures less
    efficientAND NO BENEFIT regarding safety /
    certification speed.

17
Status quo How works sailplane development
today?
  • A a typical sailplane manufacturer
  • the whole company employs 50 to 150 people
  • the design team consists of 2 to 5 engineers
  • typical time in the company for the employees
    10 to 30 years!
  • typical time for the company to be in the
    business of building gliders at least 10 years,
    sometimes over 50!

18
Status quo How works sailplane development
today?
  • Inside a typical sailplane manufacturer
  • typical number of contractors regarding design
    and certification none or (very rare) one!
  • maximum manufacturing depth - only the materials
    and standard parts are bought - the entire
    sailplane is produced in-house by the
    manufacturer
  • designers, workers and managers mostly have
    personal experience in the operations of their
    products(i.e. competition gliding, club
    operations, instruction)

19
Status quo How works sailplane development
today?
  • The typical design organisation of a
    manufacturer
  • verification of certification documents
  • planning of certification tasks with authorities
  • proper documentation and record keeping of design
    and certification documentation
  • classification into TC / STC / major and minor
    changes together with authorities
  • information of owners of products
  • control of defects and other problems toward
    airworthiness
  • gt all basic principles of a Part 21 DOA are
    fulfilled!

20
Future of DOA What is needed for light
aviation?
  • The basic needs for light aviation
  • small design organizations do not need the
    intensive procedural control, but sometimes
    competent technical assistance
  • the administrative complexity in the
    certification process shall be reduced
  • delegation of responsibilities to the companies
    is possible and appreciated but it has to be
    economical feasible during introduction and daily
    operations

21
Future of DOA What is needed for light
aviation?
  • How should the certifying / inspecting body (EASA
    / NAA under task allocation / assessment bodies)
    work?
  • ability to handle processes in national language
  • proven technical competence and experience
  • one-stop support, grouping of responsibilities
    (including TC and organisations certification),
    aiming at reduction of administrative burden
  • long-time availability of technical documents
    regarding type certification
  • continuity during processing

22
Future of DOA What is needed for light
aviation?
  • How should the implementation of the DOA rules
    be?
  • representatives of the authorities need personal
    experience with the products / kind of companies
  • the often quite long experience as design
    organisation has to be honoured - old privileges
    must continue
  • inclusion of procedures into the manuals which
    are not needed (because of the tiny design
    organisations) should be avoided
  • logical would be issuance of DOA by the persons
    who oversee the production organisation of the
    manufacturer or who work in the type
    certification process

23
Future of DOA What is needed for light
aviation?
  • How should the design organisation manual look
    like?
  • if chosen by the applicant national language
    should be possible
  • description of the company structure the
    co-operation between design and production
    department
  • only basic description of the typical design
    certification process - no in-depth regulation /
    description of procedures within the company
  • listing of the members of the design organisation
    with their respective roles and privileges

24
Future of DOA What is needed for light
aviation?
  • Last but not least a word on the financial side
  • gliding / light aviation is an economical small
    part of the European aviation community
  • these small companies cannot finance
    significantly EASA
  • nevertheless they provide an important foundation
    of aviation
  • gt make simple rules for the simple light
    aviation gt reduce costs for EASA and the small
    manufacturers
