Purpose and description
Enable an agent to identify the Yakovlev SJ-100 design, distinguish its configurations from earlier Superjets, and determine which capability, approval and support claims apply.
The Yakovlev SJ-100 is a Russian twin-engine regional passenger jet developed from the Sukhoi Superjet 100, with redesigned systems intended to replace imported equipment and use Russian PD-8 turbofan engines.
It can be Classify a supplied aircraft description against documented SJ-100 baselines and flag ambiguous Superjet naming.; Compare SJ-100 and predecessor capabilities using matched configurations and measurement assumptions.; Identify the approval documents required to evaluate a proposed operation.; Trace a subsystem replacement to affected performance claims, manuals and support requirements.; Screen cabin or airport suitability using configuration-specific evidence.; Flag missing evidence that prevents a compatibility, maintenance or operational decision..
Distinguishing features
Require a documented SJ-100 design or configuration reference; a Superjet name, photograph or airline livery alone does not establish membership.
Check the propulsion baseline: Yakovlev lists two PD-8 turbofans for its SJ-100 product. [Manufacturer product page](https://yakovlev.ru/products/sj-100/)
Do not use engine type as the sole identity test: Yakovlev explicitly identifies its first SJ-100 prototype as using SaM146 engines. [Manufacturer first-flight release](https://eng.yakovlev.ru/press-centre/releases/import-substituted-superjet-performed-its-maiden-flight/)
Distinguish the derivative through documented replacement-system configurations, including avionics, landing gear, auxiliary power and control systems, rather than assuming it is only an engine change.

Scope
+ SJ-100 designation, Superjet ancestry and configuration boundaries
+ PD-8 propulsion integration and the treatment of development aircraft with other engines
+ Replacement aircraft systems and their configuration dependencies
+ Configuration-specific passenger capacity, performance and airport requirements
+ Certification evidence, operating limitations and maintenance applicability
- Generic aircraft aerodynamics and jet propulsion principles
- Earlier SSJ100 configurations except where needed to establish ancestry or differences
- PD-8 and SaM146 engine designs as independent products
- Individual aircraft ownership, flight histories and live technical logs
- Airline scheduling, ticket sales and route economics
- Yakovlev corporate governance and manufacturing-site management
Characteristics
- Design identity and ancestry
- Registry entry linked to manufacturer designation, predecessor design and authoritative type-design reference Prevents branding changes from creating duplicate models or incorrectly merging distinct configurations.
- Configuration baseline
- Documented baseline identifier; prototype, certification-test or production configuration Determines which specifications and evidence can be applied.
- Propulsion installation
- Engine model, installation standard, control-system revision and applicability Separates PD-8 product claims from SaM146 development evidence and identifies integration dependencies.
- Replacement-system coverage
- Subsystem mapped to equipment identity, supplier evidence, revision and applicable baseline Makes import-substitution claims inspectable without treating national origin as proof of compatibility.
- Passenger accommodation
- Seats by cabin layout, seat pitch in mm and approved occupancy limit Separates advertised capacity from the capacity supported by a particular cabin and approval.
- Mass and payload limits
- kg; maximum take-off, landing and zero-fuel masses, with payload assumptions and configuration Supports meaningful comparisons without borrowing predecessor limits.
- Mission performance
- Range in km, cruise speed in Mach or km/h, fuel in kg; payload, reserves and atmospheric assumptions attached Prevents an advertised range from being mistaken for a guaranteed route capability.
- Airport compatibility envelope
- Dimensions and runway distances in m; pavement, servicing and environmental constraints Identifies the evidence needed before claiming compatibility with an airport.
- Approval status
- Unknown, under evaluation, approved, restricted, suspended or superseded; dated by authority and configuration Keeps demonstrated flight capability separate from permission for a specified operation.
- Maintenance applicability
- Applicable manual revisions, directives, service bulletins, parts eligibility and life limits in hours, cycles or calendar time Prevents unsupported reuse of earlier Superjet maintenance assumptions.

Drafted structure
Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 17 findings · 27 questions.
Superjet identity and design boundary Establish what the registered SJ-100 name denotes and how it relates to earlier Superjets.
The entry lacks a definition, and name continuity can conceal differences between a family, derivative and test configuration.
Designation and lineage
Connect registry naming to manufacturer and approval terminology.
Naming does not settle registry coverage
Record the evidence needed to decide whether this entry denotes the import-substituted derivative or a broader renamed family.
- Which manufacturer or registry provenance record defines the intended coverage of vr.tr.yakovlev-sj-100? provenance
- Does an existing Superjet world model already own this concept, requiring a link instead of a second model? boundary
Baseline membership
Distinguish development configurations from the product baseline.
Prototype engine exception
The first SJ-100 prototype used SaM146 engines, so membership cannot be inferred from PD-8 installation alone. [Yakovlev release](https://eng.yakovlev.ru/press-centre/releases/import-substituted-superjet-performed-its-maiden-flight/)
- Which design records establish an aircraft's SJ-100 baseline independently of its installed engines? definition
- Which results from a SaM146-equipped prototype are explicitly applicable to a PD-8 configuration? boundary
Propulsion and replacement systems Describe the equipment changes that distinguish the SJ-100 derivative.
Replacing propulsion and onboard systems creates interfaces and evidence requirements that predecessor specifications cannot settle.
PD-8 installation
Model the aircraft-level consequences of the propulsion baseline.
Installed propulsion baseline
Yakovlev identifies two PD-8 turbofans for the SJ-100; installation-specific limits must be obtained separately. [Product page](https://yakovlev.ru/products/sj-100/)
- Which PD-8 installation and control-system standards belong to each SJ-100 baseline? definition
- What approved thrust ratings, fuel specifications and installation limits apply to that baseline? measurement
Replacement-system integration
Track equipment changes and dependencies across the aircraft.
Replacement is system-specific
Manufacturer reporting identifies replacement avionics, landing gear, auxiliary power, integrated control and electrical systems; each needs its own applicability evidence. [Yakovlev test release](https://yakovlev.ru/press-centre/releases/importozameshchennyy-sj-100-zavershil-zavodskie-dovodochnye-ispytaniya/)
- Which equipment identifiers and revisions substantiate replacement claims for each SJ-100 baseline? provenance
- Which equipment or software changes require coordinated changes elsewhere in the aircraft? action
Regional transport capability Capture usable passenger, payload and airport envelopes for a specified SJ-100 configuration.
The derivative's capability must be supported by its own configuration evidence instead of inherited Superjet marketing figures.
Cabin and mission
Relate passenger accommodation to payload and range assumptions.
Configuration-bound capacity
Treat seating, payload and range as linked claims whose layout, mass and reserve assumptions must be recorded.
- What passenger layouts and occupancy limits are documented specifically for the SJ-100 configuration? measurement
- Under which payload, fuel-reserve and atmospheric assumptions are its range and fuel-consumption figures stated? measurement
Airport and environment
Connect the aircraft configuration to airport and operating-condition constraints.
Airport compatibility evidence
Require SJ-100-specific geometry, ground-service interfaces and performance evidence before transferring predecessor airport compatibility claims.
- What dimensions, pavement requirements and ground-service interfaces are documented for this baseline? measurement
- Which approved performance data support assessment of a proposed runway, elevation, temperature and surface condition? action
Approval and operating authority Separate design maturity, regulatory approval and permission for particular operations.
Prototype flights, production milestones and certification announcements support different conclusions about the SJ-100.
Certification applicability
Identify the governing authority, approval instrument and covered configuration.
Dated approval evidence
Current approval status remains unresolved until supported by an authoritative record with configuration and jurisdiction coverage.
- Which Rosaviatsiya certificate, amendment or other approval instrument covers the SJ-100, and what certification basis does it name? provenance
- Which engine, equipment and cabin configurations are included or excluded by that approval? boundary
Limitations and dispatch
Identify the documents needed to assess operating modes and degraded-system conditions.
SJ-100 operating documentation
Record applicable flight-manual limitations, protection descriptions and dispatch provisions without presuming earlier SSJ100 procedures transfer.
- Which SJ-100 manual revisions define control modes, protections, warnings and operating limitations? provenance
- What configuration-specific dispatch provisions and aircraft-instance evidence are required to assess operation with a reported defect? action
Continued airworthiness and support Determine how the SJ-100 configuration is maintained and which support resources apply.
Replacement equipment changes parts eligibility, maintenance tasks and the relevance of predecessor service experience.
Maintenance and parts
Connect the baseline to maintenance instructions, consumables and eligible components.
Maintenance transfer needs evidence
Require explicit applicability for inherited Superjet tasks, tools, consumables and parts, particularly across propulsion and replacement-system boundaries.
- Which manuals establish SJ-100 inspection intervals, life limits and approved consumables? provenance
- Which predecessor parts, tools or maintenance tasks are explicitly approved for reuse on each SJ-100 baseline? boundary

Separate prototype observations, predecessor fleet experience and SJ-100 service evidence when assessing failure modes and support maturity.
- Which documented failures concern SJ-100 replacement systems, and what test or service exposure supports their interpretation? provenance
- Which directives or service bulletins require action for the affected configuration, and how is compliance established? action
