As the early stages of transitioning from summer to fall travel season begin, aftermarket parts demand for July shows a more diversified demand than June 2026.

Reports from Locatory.com identify two developments that frame the month’s aftermarket demand, stating, “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.”

They continue, “And narrowbody and regional fleets, still undersupplied by new deliveries, continue to carry more of the flying than they were built for. Both dynamics show up in this month's data.”

Why did demand for airframe and landing gear components shift in July 2026?

Showcasing a clear regional shift in demand from last month’s report, airframe and landing gear parts make up 24% of search data in North America and 10% if search data around the globe.

The most highly searched airframe and landing gear components in North America show as:

• Pin Assy (PN: 83647-14-1) for A320 family
• Upper Heat Shield (PN: 321-475-152-6)
• Fairing Assy (PN: 4-60007H883-00)
• Panel Assy (PN: FW19488)
• Air Cycle Machine (PN: 1263A0000-03) for A320 family
• Wheel Assy NLG (PN: 3-1596) for A330

Locatory.com experts note that this is largely due to North American networks running shorter, higher-cycle domestic sensors, which wear down landing gear components more quickly than flight hours.

The reports state, “For MROs and lessors in the region, this makes landing gear availability the more immediate dispatch risk this summer.”

Landing gear and airframe components that were highly searched in both the North American and global data sets for July 2026 include: 

• Main Landing Gear Brake Assy (PN: C20534100) for A321
• Nose Radome Assembly (PN: D53132210000) for A320 family
• Radar Nose Dome Assy (PN: D53132110000) for A320 family
• Thrust Reverser Cowl Opening Actuator Assy (PN: 1FA14012-8) for B737
• Servo Control Elevator (PN: 31075-840) for A320 family
• Latch Assy (PN: 91049-18) for B767

What was demand like for cabin and safety components in July 2026?

How can maintenance providers plan smarter according to parts demand?

Locatory.com reports advise, “As the summer flying peak gradually turns attention to the autumn maintenance period, procurement demand is likely to shift.”

The reports note that MROs and airlines can respond to this by transitioning from protecting peak-season dispatch reliability to preparing for efforts like:

• Scheduled inspections
• Engine removals
• Winter maintenance inputs
• Heavier shop visits

“The hours and cycles accumulated during peak operations will show up in the aftermarket as scheduled material demand,” conclude Locatory.com experts.
