Top Aircraft Landing Gear Systems Companies

Safran SA

Fleet driven overhaul cycles are translating into steady service pull through, and that favors a leading company with both OEM design authority and mature overhaul capacity. Safran Landing Systems reinforced its support network through its Landing Life portal and renewed structured support with Revima for Airbus landing gear overhaul, which supports reliability commitments at operator level. Faster A320neo and A350 induction would expand rotable pool utilization in an upside case, while titanium and complex forging bottlenecks remain a key risk that can delay shipset availability. The company's moat comes from certification depth and long lived repair data that smaller shops cannot easily replicate.

Leaders

Collins Aerospace (RTX Corporation)

Capacity additions in Eastern Europe signal a deliberate push to protect delivery schedules and shorten internal lead times. Collins Aerospace, a top manufacturer, is expanding its Tajcina, Poland site to ramp landing gear system output, with construction starting in November 2024 and completion targeted for February 2026. If narrowbody and defense build rates firm up, this added footprint should reduce single site risk and support faster recovery from supplier disruptions. The main downside is execution risk during ramp up, where quality escapes can trigger costly rework and regulatory scrutiny. Collins benefits from deep integration across gear, steering, and control functions, which strengthens switching costs for airframers.

Leaders

Liebherr Group

China program support has become a visible proof point for engineering responsiveness and localized customer support. Liebherr-Aerospace received recognition from COMAC tied to its C919 landing gear system support, and it has continued to deepen repair coverage with partners for C909 and C919 related component maintenance. Liebherr, a major supplier, also expanded service capacity in Michigan, which should help absorb rising overhaul volume as fleets age. The upside case is stronger uptake of digital health monitoring tied to landing gear and hydraulic components, while the main risk is certification pacing for design changes that touch safety critical load paths.

Leaders

Hroux-Devtek

Ownership transitions can distract leaders, but they can also unlock faster capital investment for machining and assembly constraints. Hroux-Devtek reported stronger profitability and higher sales in the quarter ended September 30, 2024, while also outlining the path to a take private transaction that closed in February 2025. Accelerated investment in finishing and assembly capacity is a realistic upside scenario that would reduce backlog risk at its landing gear focused sites. The main threat is customer concentration on a few large programs, where a production rate cut can quickly hit utilization. The company's strength is fracture critical process discipline that supports repeatable overhaul quality.

Established

Triumph Group, Inc.

Aftermarket induced overhaul cycles create an opening for specialized actuation work that is hard to replicate quickly. Triumph discloses landing gear system design and landing gear actuation capabilities in its SEC filing, and it also won a U.S. government contract for C-5 main landing gear actuators with performance running through October 2031. As a major supplier in actuation, it can capture widebody overhaul pull through if 787 and A380 shop visits rise faster than expected. The main risk is execution variability across sites, where late parts can cause aircraft on ground events for airlines. Its advantage comes from deep repair know how on legacy hydraulic architectures.

Established

GKN Aerospace

Defense sustainment work can stabilize demand, yet it can also lock teams into strict configuration control and slower change cycles. GKN Aerospace's Fokker landing gear operation delivered the first serviced F-35 wheels and brakes assemblies for the European fleet, showing real throughput on a demanding platform. As a key participant with broad aerospace content, it can cross apply repair engineering and industrial methods, but landing gear specific innovation may lag pure play specialists. If European fighter sustainment expands, GKN can scale MRO revenue, although any quality slip in overhaul documentation could cause immediate operational grounding exposure for customers.

Established

Eaton Corporation plc

Program selection on next generation vertical lift platforms can validate hydraulic power and conveyance designs under harsh duty cycles. Eaton was selected by Bell to provide hydraulic power generation and conveyance solutions for the U.S. Army FLRAA program, which supports landing system functions that rely on dependable hydraulics. As an aerospace focused supplier, Eaton can scale through common hardware families, but it must manage long qualification timelines and strict change control. Broader content pull through into panels and accumulators is a plausible upside, while the core risk is supply continuity for precision parts that airlines and defense depots expect on fixed schedules.

Performers

Whippany Actuation Systems LLC

Electrification is pushing landing gear functions toward lighter actuators and simpler maintenance, which fits a niche specialist well. Whippany positions landing gear actuation as a core focus, including electric nose wheel steering and extend retract uplock actuation used on commercial and military applications. If airframers accelerate more electric architectures, Whippany could move from component supplier to systems level partner, but certification cost and test capacity can become binding constraints. The critical downside is dependence on a limited number of platform wins, where a single program delay can stall revenue. Its strength is clear product focus and fast engineering cycles versus larger diversified groups.

Performers

Parker-Hannifin Corporation

Aftermarket strength in aerospace components can support steady investment, even when other segments soften. Parker's investor disclosures highlight record company performance in fiscal 2024, and Reuters reporting points to continued demand strength in its aerospace business, which supplies aircraft systems and aftermarket services. As a key supplier, Parker can benefit when airlines shift to repairable pool strategies that favor dependable turnaround. The upside case is deeper content on landing gear related hydraulics and controls, but the main risk is capacity constraints in high mix repair shops that can cause long lead times. Quality escapes can carry outsized cost because parts sit on safety critical pathways.

Performers

Honeywell International, Inc.

Widebody brake support agreements can lock in long duration overhaul volume when reliability and turnaround are proven. Honeywell was selected by Emirates under a 10 year agreement to provide wheels and carbon brakes for its A380 fleet, with maintenance performed through Emirates shops in Dubai. This supports landing system performance through predictable repair loops, but the firm's broader portfolio can dilute landing gear specific focus versus specialists. The upside case is using brake material improvements to extend removal intervals, while the main risk is supply continuity for repair parts when global demand spikes. Its strength is mature braking know how and embedded airline relationships.

Aspirants

Magellan Aerospace Corporation

Complex machining and casting depth matters because landing gear structures demand tight tolerances and stable metallurgy. Magellan signed a long term agreement extension with Collins Aerospace to produce complex magnesium and aluminum castings supporting multiple aircraft programs, reinforcing a role in upstream manufacturing that can feed landing system supply chains. It also expanded long bed machining capacity in the United Kingdom for Airbus single aisle structural components, which can improve throughput discipline and inspection capability. The upside case is winning more turnkey machining packages tied to landing gear elements, while the key risk is being re-source deprioritized when primes re-source critical parts to reduce supplier count.

Aspirants

CIRCOR International, Inc.

Emergency extension functions are safety critical, and that creates a clear value pocket for focused flow control designs. CIRCOR Aerospace won a contract from Safran Landing Systems to develop and produce an emergency extension pneumatic module for the U.S. Army MV-75 FLRAA program, anchored in its New York facility. The company also completed its acquisition by KKR, which may support faster capital deployment for production readiness and test equipment. Follow on content across other landing gear safety subsystems is a realistic upside, while the key operational risk is meeting qualification timelines under aggressive defense program schedules.

Aspirants

SPP Canada Aircraft, Inc.

Legal entity status can limit contracting flexibility, even when the parent group retains deep technical capability. A public registry entry updated in March 2025 lists SPP Canada Aircraft, Inc. as inactive, which raises practical questions for new in country awards. In parallel, Sumitomo Precision Products describes ongoing landing gear design and manufacturing capability, including participation on CRJ regional jet landing gear programs, which suggests technical depth still exists within the broader corporate group. The best case is a reactivation or restructuring that restores North American execution capacity, while the key risk is customer reluctance due to governance and support clarity.

Aspirants

Singapore Technologies Engineering Ltd.

Network decisions matter in component heavy MRO because they shape turnaround time, staffing, and customer confidence. ST Engineering announced a capacity transition plan for its U.S. airframe MRO operations, consolidating work into other U.S. sites, which may affect how landing gear adjacent component flow is managed across its footprint. If it improves utilization and reduces overhead, the move can become an advantage for a leading service provider, but the transition brings execution risk around labor retention and process continuity. The upside is stronger responsiveness for airlines that want predictable induction slots, while the downside is short term disruption that pushes work to rivals.
