Each projectbegins with an extensive
planning assessmentwhere we look closely
at feasibility, cost efficiencies,and optimal
certification paths.
This ensures thatthe projectis launched
with strong economic footing and
dependable timeline expectations.
OUR SEVEN STEP “CONCEPT TO COMPLETION” PROCESS
Planning
Once the projectscope has been clearly
defined, we begin the prototype design
process modeled in a 3D CAD platform with
powerful simulation and design validation
capabilities.
Concurrently we run our procurement
discovery process, toestablish
componentand material selection based
on suitability, price and availability.

9. DESIGN ENGINEERING 9
When the conceptis approved by the client,
we initiate an engineering design review
process.
Designs are substantiated using a
balanced approach of traditional and
higherorder analyses. Data generated is
documented by LCAS engineers to
support certification, testing,
manufacturing and maintenance.
Engineering Analysis
As an approved Canadian Aeronautical
components manufacturerwith an extensive
palette of in-house capability, we don’t need
to rely on third party availability to turn your
concepts into reality.
Unlike many other engineering shops,
we keep everything underone roof,
ensuring time line and cost expectations
are keptin check.

Once the assembly is complete, we will
establish an integration plan that is
determined by client geo-location and
projectscope. Based on client requirements,
we can…
Send a team to the client’s location to
complete the integration.
Provide many of our modifications in ”kit
form” to be installed by the client.
In most cases, the integration is
completed at our accessible facilities.
Integrate
LCAS has extensive experience supporting
testing for projects of any size.
We provide flight testcoordination, static
load testing, statistical reliability testing as
well as conformity inspections and
specialized inspections.
Our full suit of instrumentation is
maintained by LCAS quality assurance and
is NIST traceable.
LCAS provides flight testcoordination
through our network of trusted flight test
professionals.

PRODUCTIONTYPE DESCRIPTION
PROTOTYPING
Our specialty is taking your idea and turning it intosomething youcan touch and feel as quickly as possible.In the early stages of
product development,it is important to see the physical manifestations of initial concepts so that the fine-tuning will
incorporate solutions to the real worldissuesthat can often only be identified in a tangible model.We get it done quickly so our
customers can move on to the next phase of their project in the most time efficient manner.
PART REPAIR &
OVERHAUL
As Transport Canada Civil Aviation Approved Organization,we can facilitate repairs to damaged parts that are more economical
to repair or overhaul then to replace.We take consultative approach and ensure our customers have a clear understanding ofthe
