As global and North American parts searches both show the same constraints in July 2026, data suggests a systemic availability issue rather than a region-specific shortage.

According to reports from Locatory.com, “July’s shortage data is more concentrated than the search data. While searches covered a wide range of aircraft systems, the hardest-to-find list centered on GE90 engine controls, HMUs, FADECs, airframe structures, latches, brackets, cabin items, electrical modules, sensors and retainers.”

Why is engine and fuel control the most constrained component category for July 2026?

Locatory.com reports share, “Engine-related parts were the largest shortage category, accounting for 31% of both global and North America hardest-to-find lists. The strongest concentration was around GE90 / B777 engine-control and fuel-control material.”

These constrained engine and fuel control parts from July 2026 include:

• Hydro Mechanical Fuel Control Unit (HMU) (PN: 8061-684 / 8061-685 / 8061-686 / 8061-918) for GE90 / B777
• FADEC (PN: 105E70898G1 / 105E70898G2 / 105E70898G3) for GE90 / B777
• Hydromechanical Unit / HMU (PN: 1693M75P08) for GE90 / B777
• Check Valve (PN: 1548-05-12) for GE90 / B777
• Case Assy CFM56-5 FCOC (PN: 34831-1583)
• Starter Valve Assy (PN: 350-708-806-0)
• Oil Level Sensor Assy (PN: 350-711-801-0) for GE90 / B777
• Ball Rotor (PN: 2923151-102)

Experts from Locatory.com note that disclosures from GE Aerospace could be a major influence on parts shortages related to engine systems.

They explain, “In May 2026, the manufacturer reported that approximately 70% of the GE90 fleet had not yet undergone a second shop visit. GE said these visits typically involve around 50% more work than first shop visits because they include additional compressor-related maintenance.”

The reports continue, “GE Aerospace also reported that, over the last 12 months, Commercial Engines & Services internal shop-visit revenue had increased by approximately 30%, while spare-parts revenue had grown by more than 25%.”

“As more GE90 engines enter heavier second-shop-visit workscopes, demand can spread beyond major modules and life-limited parts to controls, sensors, valves and accessories needed to complete the engine build and return it to service,” note Locatory.com experts.

They add, “In addition, Boeing has confirmed the 777X will not enter service until 2027, keeping 777-300ER and 777F fleets in front-line widebody service longer than airlines had planned, creating this maintenance demand.”

What are the hardest-to-find airframe and landing components of July 2026?

Airframe and landing components make up the second-largest category of parts with shortages in July 2026, holding 26% of the share.

The same constrained airframe and landing parts appear in data from both North American and global markets, such as:

• Latch Assy (PN: 0FV9900A11G02)
• Bracket Assembly (PN: 277-1822-501)
• Bumper Assembly (PN: 315N3555Y8)
• Bracket (PN: 47138-2)
• Bracket Support, Steel (PN: 612C9505-009)
• Aluminum Retainer (PN: 65B10920-609) for B747
• Retainer (PN: 720289-14)
• Tie Rod, Aluminum Alloy (PN: ABS1263A72600WG) for A320 family
• Door Landing (PN: CC670-33151-6S) for Bombardier CRJ series
• Kamatics Bearing (PN: KRP183614VT)

Which electrical, avionics and sensor components were hardest to find in July 2026?

While electrical, avionics and sensor-related components make up a smaller share of the hardest-to-find parts at 17%, there are several items that appear in both datasets for July 2026.

These include:

• Temperature and Pressure Sensor (PN: 0154GF9) for GE90 / B777
• Main Power Supply (PN: 10074910-114)

What constraints do cabin, safety and interior components show for July 2026?

For cabin, safety and interior parts, constraints represent 14% of the evaluated parts shortages for the month.

Locatory.com reports identify the following cabin, safety and interior components as most constrained in July 2026:

• Light Assembly (PN: 0447LS13-087-02)
• Face Panel (PN: 0YZ1510A01G03)
• ECS-PAO (PN: 623Z1060-180) for B787

• Literature Pocket Assy / Pochette (PN: F0426595)

How hard to find were standard hardware and seals in July 2026?

Standard hardware shows the smallest constraints during July 2026, making up 12% of the hardest-to-find components. This is a significant shift from June 2026, when these components accounted for 20% of shortages, the third-largest of all categories.

Standard hardware and seals showing shortages from July 2026 include:

• Rivet (PN: CR3524EE-6-04) for B787
• Bolt (PN: 2021811-2)
• Bearing Set (PN: 219678-1)
• Seal Attachment (PN: 85414892-103SP)

How MROs and repair shops can respond to parts shortages

According to Locatory.com experts, “Procurement teams should therefore begin securing critical rotables, confirming repair capacity and reviewing exchange-pool exposure before autumn demand intensifies.”

They continue, “Particular attention should be given to components with limited interchangeability, long repair turnaround times or repeated appearance in hard-to-find searches.”
