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)
