Prime Propulsion provides FAA test cell correlation consulting for MRO facilities, engine overhaul shops, and test operators across all engine types. We understand what the FAA expects in a correlation package — because we've reviewed them from the other side. Turnkey service or DER review of your existing package.

FAA TEST CELL CORRELATION
BY ENGINE TYPE
We provide test cell correlation services across all certificated engine types. APU correlation is a rapidly growing area — aging regional and business aviation fleets are driving increased demand for APU overhaul capability and the test cell approvals that support it.
01
UNDERSTAND BEFORE SCOPING
Auxiliary power unit test cell correlation is one of the fastest-growing segments in MRO certification. As regional jet and business aviation fleets age, APU overhaul demand is increasing — and FAA-approved test cell capability is the gating requirement. We develop APU correlation packages for fixed-wing and rotorcraft APU types across all major manufacturers.
02
DER-LED FROM DAY ONE
Test cell correlation for high-bypass and low-bypass turbofan engines and turbojet engines across commercial, business, and regional aviation applications. Package development covers instrumentation documentation, test procedure development, and statistical correlation analysis demonstrating equivalence to the OEM's reference test cell standards. Many turbojet-powered fleets are in late service with reduced OEM support — independent test cell approval is increasingly critical for MROs maintaining these assets.
03
CLEAN PACKAGES, FEWER CYCLES
Correlation packages for turboprop and turboshaft engine test cells spanning regional aviation, general aviation, and rotorcraft applications. Turboprop overhaul facilities frequently require new correlation documentation when instrumentation, cell configuration, or reference standards change. Helicopter MRO operators overhauling certificated turboshaft engines require approved test cell correlation before returning engines to service under 14 CFR 43.2.
WHAT WE COVER
TEST CELL CORRELATION
SERVICES
Whether you need a complete turnkey package or an expert review of your existing data — we deliver the FAA-ready documentation that gets your test cell approved.
INDUSTRY CREDENTIAL
SAE EG-1E Gas Turbine Test Facilities and Equipment Committee — our founder is a member of the SAE committee that develops the standards governing gas turbine engine test procedures and facilities. The same standards FAA reviewers reference when evaluating test cell correlation packages.
WHO WE WORK WITH
Any facility that overhauls and tests FAA-certificated engines needs an approved test cell correlation.
MRO facilities establishing new test cell operation
Overhaul shops with expired or lapsed correlation approvals
Facilities updating correlation after instrumentation changes
Operators needing independent expert review of existing packages
01
TURNKEY PACKAGE DEVELOPMENT
Full test cell correlation service — we perform the analysis, develop the complete submittal package, and produce the FAA-ready documentation. You receive a complete, organized package ready for submission.
02
PACKAGE REVIEW & SUBMITTAL SUPPORT
If your team has developed the package, we provide independent expert review against FAA and OEM requirements, identify any gaps, and support submittal preparation — without requiring a full rebuild from scratch.
03
PACKAGE GAP ASSESSMENT
Review of your existing correlation data against FAA and OEM requirements to identify gaps before submission. Prevents comment cycles and submission rejections.
04
INSTRUMENTATION DOCUMENTATION
Calibration records, instrumentation specifications, and measurement system documentation organized to meet FAA submittal requirements under 14 CFR 43.2 and applicable OEM standards.
05
STATICAL CORRELATION ANALYSIS
Engineering analysis demonstrating that your test cell produces results equivalent to the reference cell within acceptable tolerances — the core technical requirement of every correlation approval.
06
REFERENCE DOCUMENTS & REGULATORY GUIDANCE
We navigate the full matrix of applicable guidance — 14 CFR 43.2, OEM test manuals, SAE standards, and FAA advisory circulars — and ensure your package addresses every applicable requirement.
HOW IT WORKS
THE TEST CORRELATION
APPROVAL PROCESS
From initial assessment through FAA-approved package — here's how we move your test cell from unapproved to operational.
STEP 01
ASSESSMENT & SCOPING
We review your test cell configuration, existing data, engine type, and OEM reference standards to determine exactly what the correlation package requires. No surprises mid-program.
STEP 02
PACKAGE DEVELOPMENT & REVIEW
We develop or review the full correlation package — instrumentation documentation, test procedure, and statistical analysis — producing a complete, organized package that addresses every FAA and OEM requirement before submission.
STEP 03
FAA SUBMISSION & APPROVAL
We submit a complete, organized package that addresses all FAA requirements upfront. Our former FAA engineer experience means we know what triggers a comment — and how to prevent it.
