01 / 07
Avionics Propulsion Airframe Support Equipment

PartYard covers a broad aerospace supply envelope, from high-value propulsion and landing systems to recurring maintenance items and specialist training hardware.

Even when the exact line item is not shown, the supplier network allows PartYard to source adjacent components, alternates, and OEM-backed options on request.

Best For
  • Users who know the system or component family they need.
  • Procurement teams building a shortlist before RFQ.
  • Maintenance planners mapping recurring support categories.
F135 F119 F117 PW980 APS5000

Engine coverage includes both military propulsion programs and auxiliary power units used across demanding operational environments. This is the lane for users prioritizing thrust systems, support assemblies, and engine-related sustainment.

Representative lines include F135, F119, F117, F100, PW4062/F139, TF33, plus APU families such as PW980, APS5000, APS3200, PW901A/C and APS2300.

Use Cases
  • Military engine support and replacement planning.
  • APU procurement for mission readiness and turnaround.
  • Program-led sourcing aligned with OEM references.
BAK12 WT44B-2D WT44B-2C MAAS

Aircraft arresting systems speak to a specialist buyer and should not be buried in a generic list. The new layout makes that specialization visible immediately instead of hiding it inside a long two-column stack.

Coverage includes fixed and mobile arresting solutions used to improve runway recovery capability and operational safety.

What This Covers
  • Runway arresting equipment families.
  • Mobile aircraft arresting system programs.
  • Support conversations for specialist airbase infrastructure.
F/A-18 A400M ATR 42/72 A320 / A330 / A350

Landing systems coverage spans mixed fleets, which is why the revised content emphasizes aircraft family examples rather than an uninterrupted paragraph. Users can confirm compatibility breadth before reading the sourcing note.

Examples include Boeing F/A-18 and 787 families, Bombardier Global and Challenger programs, A400M, ATR 42/72, Airbus A320, A330 and A350, and Eurofighter Typhoon landing gear support.

Fleet Relevance
  • Mixed military and commercial gear support.
  • Programs with recurring overhaul and replacement needs.
  • Operators balancing compatibility and readiness.
Spec Lubricants Greases Degreasers Anti-Seize

Not every procurement journey starts with a complex assembly. Lubricants and maintenance consumables drive repeat demand, so they deserve a cleaner, faster access point in the experience.

The range includes military, industrial and commercial grade lubricants, greases, degreaser solvents, and premium anti-seize compounds through Armite-backed supply coverage.

Why It Matters
  • High-frequency replenishment category.
  • Useful for maintenance teams and stock planners.
  • Less technical entry point for fast quote requests.
DRLMS Weather Radar EP-80 Griffen-2

Radar simulation used to be buried in dense text. Here it becomes a distinct specialist module, making it easier for technical buyers to identify the capability without scanning the entire page.

The category includes custom embedded radar simulators, digital radar landmass simulation, weather radar simulation, and supporting image generation and projection systems such as EP-80, EP-8100, Griffen, Matrix and Panorama platforms.

Suitable For
  • Training systems and simulation procurement.
  • Programs needing display, dome, or projector support.
  • Buyers seeking specialist rather than generic air parts.
Avionics Batteries LRUs Structure Parts

This lane collects the practical, everyday interior and replaceable support items that users often need fast. Instead of a long list buried at the bottom of the old section, the new version frames it as a dependable operational category.

Coverage includes avionics and instruments, batteries and chargers, line replaceable units, consumables, engine parts, structure parts, and used serviceable material.

Typical Needs
  • Routine replacement and sustainment requests.
  • Mixed-condition sourcing including serviceable items.
  • Broader support packages rather than one-off specialist systems.
Deicers Engine Stands GPU Towbars

Tronair anchors the brand view with a clear ground-support narrative. Users searching by OEM can immediately see the operational context instead of parsing a generic vendor card.

The range covers deicers, engine stands, ground power units, servicing equipment, tooling, towbars, and airport ground vehicles, backed by Tronair's established safety and engineering reputation.

Brand Signal
  • Strong match for ramp and support equipment buyers.
  • Recognizable OEM-led trust cue.
  • Clear separation from parts-only sourcing lanes.
Air Filters Batteries Fuel Systems Sensors

Saywell is presented as a broad-access brand for recurring aerospace consumables and spares. The updated layout highlights the fact that this is a practical, catalogue-like supply lane rather than a specialist engineering story.

Representative items include air filters, pumps, de-ice boots, batteries, connectors, bearings, control cables, engine accessories, fittings, fuel system items, propellers, sensors, gauges, thermocouples, and wheels.

Useful When
  • Users need a broad spares basket from one trusted source.
  • The enquiry starts from part family but resolves to a brand.
  • The goal is speed and breadth, not a single flagship product.
F135 F119 PW980 APS3200

Pratt & Whitney becomes the OEM-focused counterpart to the propulsion category. This matters for users who think in terms of approved brands first and only then narrow into the exact engine or support requirement.

Coverage includes military engine lines such as F135, F119, F117, F100, PW4062/F139 and TF33, alongside APU families including PW980, APS5000, APS3200, PW901A/C and APS2300.

Why Users Pick This
  • OEM-first sourcing workflows.
  • Programs with strict approval or documentation expectations.
  • Buyers comparing engine support by manufacturer.
Embedded Radar DRLMS Panorama ProSim

Collins Aerospace gives the simulation capability a trusted manufacturer anchor. The revised design lets users understand that this is not just generic simulation content but a recognizable technology supply path.

Included solutions span custom embedded radar simulators, digital radar landmass simulation, weather radar simulation, and image generation and display systems such as EP-80, EP-8100, Griffen, Matrix, Panorama, and ProSim.

Ideal Audience
  • Simulation and training buyers who search by OEM.
  • Teams needing trusted display and projector ecosystems.
  • Users validating specialist capability fast.
Gas Sensors IMU Pressure Switches Thermostats

Honeywell is now framed around controls and sensing rather than a long uninterrupted component chain. That small change makes the offer easier to grasp in seconds.

Coverage includes switches, flap selectors, gas sensors, inertial measurement units, load cells, particle sensors, potentiometers, pressure sensors, proximity sensors, shifters, speed sensors, temperature sensors, thermostats, and toggles.

Good Match For
  • Subsystem-level controls and sensing enquiries.
  • Users comparing electronic and instrumentation brands.
  • Teams validating breadth before a detailed RFQ.
C-130H P-3C Orion F-16 Fleet Support

Lockheed Martin is positioned here as a fleet support entry, not just a logo. That gives the user an immediate sense of platform relevance and helps the card feel more actionable.

PartYard supports Lockheed Martin systems and aircraft including C-130H Hercules, P-3C Orion, and F-16 programs, with emphasis on supply chain support, maintenance responsiveness, and operational readiness.

Decision Context
  • Useful when the enquiry starts from fleet type.
  • Supports users mapping OEM relationships to aircraft programs.
  • Creates a strong military platform trust cue.
787 Global Family A400M Typhoon

SAFRAN Landing Systems closes the brand route with a high-confidence landing gear story tied to known aircraft families. This is easier to process than the former plain text block because the fleet examples are visually highlighted first.

Coverage includes Boeing F/A-18 and 787 families, Bombardier Global and Challenger platforms, A400M, ATR 42/72, Airbus A320/A330/A350 families, and Eurofighter Typhoon landing gear support.

Why It Works
  • Users can confirm fleet compatibility at a glance.
  • Strong OEM trust for high-criticality landing systems.
  • Clear link between brand reputation and operational support.
