As aircraft utilization remains high and engine MRO capacity faces consistent constraints, searches for aftermarket parts hint at longer repair cycles and slower fleet renewal, making for challenges in sourcing aircraft components.

Many of these constraints also derive from market challenges from the first half of the year, including rising fuel prices and geopolitical tensions in the Middle East.

“Regardless of short-term market conditions, operators remain focused on keeping aircraft operational, and sustained maintenance activity remains the defining feature of the market,” said Toma Matutyte, CEO of Locatory.com.

In this article, reports from Locatory.com identify the most highly searched parts from June 2026, so MROs and repair shops can engage in smart inventory planning.

How do trends from the first half of 2026 impact parts sourcing?

Experts from Locatory.com note, “Even with Boeing and Airbus increasing deliveries this year, the global order backlog still represents roughly twelve years of production at current manufacturing rates, limiting the pace of fleet renewal.”

They explain, “This means Boeing 737 Next Generation and Airbus A320ceo aircraft, the mature CFM56-powered narrowbodies already dominating this year's search data, will continue to drive aftermarket demand well into the second half of the year and beyond.”

Why engine components show the highest search data for June 2026

Engine components show the most frequent searches in both the global and North American datasets, with procurement largely centered on engine reliability and maintenance needs.

This data continues trends from last month’s Parts Report on May 2026 data, showcasing how engine MRO remains in high demand, with a critical need for repair shops to secure engine components.

Globally, the most searched-for engine components in June 2026 include:

• HPT Rear Shaft (PN: 1864M90P04) for Boeing 737 and Airbus A320 families

• Pump (PN: 66087)
• Turbine Vibration Sensor (PN: 144-405-000-033) for A320 family aircraft

How does June 2026 search data for standard hardware differ from other categories?

According to reports from Locatory.com, “Standard hardware and seals accounted for 26% of global searches, but only 6% in North America, making this one of the most significant regional differences in June demand patterns.”

Focusing primarily on consumable maintenance items, global searches in June 2026 for standard hardware are highest for parts like:

• M83485 series O-Rings
• Self-Locking Nuts (PN: MS21043-5)
• Retaining Rings (PN: MS16624-4031)
• Pins (PN: MS39086-81)

In North America, June 2026 searches focus mainly on supporting components, such as:

• Adapters (PN: CE9410-1120)
• Couplers (PN: 5446500-001)
• Fitting-related materials

How highly searched were airframe and landing gear components in June 2026?

Reports from Locatory.com note, “Global demand covered a wider range of landing, structural and airframe support items.”

They continue, “North American demand showed a more focused profile, concentrated around braking, drainage, compressor and landing system components.”

Globally, the most frequently searched-for airframe and landing gear parts in June 2026 include:

• Probe Total Air Temp (PN: 102AH2AG) for CRJ series and B737
• Wheel Assembly MLG (PN: 3-1573-1) for Bombardier Dash 8 Q400
• NLG Actuator (PN: D23352000-3) for A330
• Mast Drain Assembly (PN: 4-60000H883-00) for Airbus fleets
• Air Cycle Machine (PN: 2206400-2) for B737

In North America, the highest-searched airframe and landing gear parts for the month show as:

• Compressor (PN: 2222254-1)
• Brake Assembly (PN: 5010520-1) for Bombardier CRJ series
• Brake Valve Assembly (PN: 71404-2) for Boeing platforms

Unlike previous months when cabin and safety components showed high volumes of search data, June 2026 data identifies this category as having the smallest concentration for both data sets, without significant trends in specific part searches.

As Locatory.com reports state, “Looking ahead, aftermarket pressure is unlikely to ease. High fleet utilization, extended aircraft service lives and constrained repair capacity will continue to reshape procurement priorities throughout 2026 and beyond.”
