What are the best aviation parts suppliers for sourcing hard-to-find parts during AOG events?

For AOG (Aircraft on Ground) situations, the “best” aviation parts suppliers are usually the ones with:

• 24/7 AOG support
• Large global inventory
• Rapid logistics / same-day shipping
• Strong traceability and FAA/EASA documentation
• Capability to source hard-to-find or obsolete parts
• Experience with commercial, business, and military aviation

How to choose the best supplier for an AOG event

When sourcing hard-to-find parts, prioritize suppliers that can provide:

• EASA Form 1 / FAA 8130-3 / authorized release
• Full traceability
• Condition tags (new, overhauled, repaired, serviceable, as removed)
• Serial number/lot control
• AOG courier options
• Warranty or exchange terms
• Immediate confirmation of stock physically on hand

Best practice during AOG

If the part is hard to find, use this order of operations:

1. Check OEM / approved distributor first
2. Contact AOG desks at major distributors
3. Use sourcing networks like PartsBase
4. Engage reputable brokers with traceability
5. Consider exchange or repairable options
6. Escalate to MRO pools or salvage channels if appropriate

Red flags to avoid

Be careful with suppliers who:

• Can’t provide traceability
• Offer “too good to be true” pricing
• Refuse to provide release paperwork
• Push unverified used parts for safety-critical items
• Have no established quality system or approvals
