Parts Report: What Was Most-Searched in February 2026?

With parts shortages, increased aftermarket demand and turbulent economic scenarios, MROs and repair shops can benefit from planning ahead in terms of inventory.

This month’s report from Locatory.com showcases the most searched parts and components for North America and the globe.

Most searched parts by type and location

Locatory.com provides the following data on the parts that were searched for most frequently in February 2026:

Why engine components are the most-searched part of February 2026

Locatory.com’s data shows that engine components make up the biggest portion of global search activity, largely driven by use of legacy fleets and high rotation rates for engines like the CFM56 family.

Locatory says, “Because of ongoing new aircraft production delays (A320neo / 737 MAX), operators continue to rely on legacy narrowbodies with deep shop visit cycles, driving intense aftermarket demand for high value rotating hardware, LLPs and critical LRUs such as fuel controls and starters.”

“External MRO capacity limitations further increase pressure on part availability, highlighting the need for timely access to critical LRUs and rotating components,” notes the report.

Most searched parts include:

• 1558M31G07 – High-Pressure Compressor (HPC) Stage 1-2 Spool, for CFM56-7B
• 442653 – Main Fuel Control Unit, for CFM56-7B
• 2116M23P01 – HPC Stage 3 Disk, for CFM56 family
• 1498M43P07 – High-Pressure Turbine Disk, for CFM56
• 63506083-4 – Starter Assy Engine Air Turbine, for B737 MAX / A320neo
• 3505830-13 – Starter Air Assy, GE90 engine, for Boeing 777

North American search data for engine components mainly focuses on Embraer E-Jet, which is likely driven by:

• Fleet composition
• MRO network concentration
• Operational intensity

As Locatory’s report notes, “These aircraft experience high daily utilization with multiple short-haul rotations, accelerating wear on critical systems. Limited OEM production capacity and extended lead times for replacement LRUs further amplify aftermarket demand, while centralized MRO hubs in the U.S. increase dependency on readily available spares.”

Most searched engine component parts in North America throughout February 2026 include:

• 4505003M – Full Authority Digital Engine Control (FADEC), for Embraer E-Jet family
• 4505008F – Fuel Module Assembly, for Embraer E-Jet family
• 4505113B – Engine Control Harness Assembly, for Embraer E-Jet family
• 4505789E – Auxiliary Power Unit (APU), for Embraer E-Jet family
• 4506256B – Air Intake Housing, for Embraer E-Jet family

What were the most highly searched electrical and power components?

Globally, search data for electrical and power components shows the most popular being:

• IDGs
• APU electronic starter controllers
• Generator contactor modules

Locatory.com’s report states, “Key drivers include high-utilization aircraft such as legacy CFM56-powered Boeing 737s and Airbus A320/A340s, where thermal and mechanical stress accelerates component replacement cycles.”

The most searched electrical/power components globally include:

• 761574B – Integrated Drive Generator (B737-600/-700/-800/-900, CFM56-7B)
• 1706903 – IDG (Airbus A320/A340)
• 730GA01Y00 – Generator Contactor Module (Airbus A320 family)
• 4508022 – APU Electronic Starter Controller (ERJ-170, A320/A330/A340)

The report also shows North American demand for these components being concentrated on regional fleets, such as Embraer E-Jets and B737 MAX aircraft.

Experts from Locatory.com explain, “The high frequency of short-haul rotations subjects solenoid valve assemblies, electric motor pumps, and APU controllers to accelerated wear, creating repeated replacement cycles.”

The report adds, “Centralized MRO hubs and OEM lead-time constraints further increase reliance on aftermarket sourcing.”

The highest-searched electrical and power components for February 2026 include:

• 756722B – Solenoid Valve Assembly (Airbus A320 / Embraer ERJ 175)
• 4951871 – Motor Electric Pump (Embraer E-Jet family)
• 96073-12 – Bracket, Attachment, Side (Embraer ERJ 170/190)
• 761574B – Integrated Drive Generator (B737NG, CFM56-7B)
• 4508022 – APU Electronic Starter Controller (Embraer E-Jet / Airbus A320

How highly searched were avionics and sensors?

Across large commercial aircraft, global demand for these components focuses on:

• Weather radar systems
• Flight sensors
• Air probes

Locatory’s report notes, “These systems are essential for navigation, safety, and compliance with increasingly stringent avionics upgrade mandates.”

Most searched parts include:

• 2041444-0404 – Weather Radar Antenna Drive Unit (A319/A320/A321, B737/B757/B767/B777, Gulfstream G650, Lockheed C-130)
• 066-50008-0409 – Weather Radar Receiver/Transmitter (B737NG/757/767/777, A300/A310/A320 series)
