Cabin Refurbishment and LOPA Changes Considerations Presented by Sofema Aviation Services (SAS) www.sassofia.com

Introduction – What is a LOPA?

LOPA stands for either Location of Passenger Accommodations or Layout of Passenger Accommodation.

Note 1: The Term LOPA has now been changed to Aircraft Interior Control Document (AICD).

Note 2: There is no regulatory requirement driving the need for a LOPA document – however, it does serve multiple useful purposes.

The LOPA is an engineering diagram outlining the aircraft’s cabin interior that includes, (but is not limited to):

  • Locations of passenger and crew seats,
  • Emergency equipment,
  • Lavatories,
  • Galleys,
  • Exits.

A detailed LOPA leads the reviewer through the complete aircraft interior design/layout and is the document that certifies the interior components and installation.

Potential Issues which may arise during Cabin Refurbishment:

Considering Project Risk

Every aspect of the project will have some level of risk inherent within the scope.

  • Identify each risk area working directly with the responsible party.
  • Capture each risk in the project planning.
  • Analyze progress in overcoming the risk areas.
  • Take immediate action when they start progressing towards becoming an issue.

Certification Issues

  • Have the products you are considering been previously certified for installation on the targeted aircraft model(s) and type(s)?
  • If not what type of testing will be required? Dynamic or static structural testing?
  • DO-160, flammability, EMI, Head Injury Criteria, abuse load, etc.?

o Tests such as dynamic testing of seats or DO-160 testing of newly designed components are often the riskier types of testing which a program can encounter.

Aircraft Type and Configuration Issues:

  • Are there multiple starting configurations (mixed fleet) in the program (i.e. differences in “starting” LOPA’s for similar aircraft types)?

o Potential Issues with existing STC’s

o Lessor “Buy-In for the Project”

Product Supply Issues:

  • Validation of the Supply of the required Product
  • Certification of the Organisation
  • Certification of the Product
  • Quality Control Process POA/ DOA agreement?
  • Technical Support and Service

Part 21 J Support

  • Is the integration firm experienced with this level/type of modification program?
  • Do they have experience with the specific airframe type(s) associated with the program?
  • Certification Plan in place (relationship with regulatory authority)
  • OEM involvement – (If required?)
  • Part 145 Facility – Capability / Manpower & Competence (Previous Experience)
  • Parts & Material Preparations

Implementation Timeline

  • Design Freeze
  • Bill of Material (BOM) release dates
  • Customer Furnished Equipment (CFE) on-dock dates
  • Certification test dates or project plan submittal milestones.

Integration

  • Interior modifications & product integration at the assembly/component level is often not provided the appropriate attention.
  • IFE integration into a seat
  • Galley insert integration into a galley unit.

Administrative Logistics

  • Location and Number of Project Stake Holders
  • Integration & Delivery Schedule
  • Ensure a comprehensive logistics plan is in place.

Training and Documentation/ Operations Manual

  • ICAW
  • User Operations Manual
  • Training Requirements
  • Live Trail / Proving Flight (WiFI / Electronic Flight Bag (EFB)
