AOG Parts Sourcing FAQ

AOG stands for Aircraft On Ground. It refers to any situation where an aircraft cannot fly due to a mechanical issue, missing part, or failed component. AOG events are the highest priority in aviation maintenance — every hour down costs money and disrupts schedules.

For AOG Priority requests, we begin immediately — 24/7. We contact verified suppliers within minutes. Physical stock confirmation takes 1–4 hours. Shipping can be same-day or next-flight-out depending on the part and location.

Standard ($300) — Business-hours sourcing for non-critical parts.
AOG Priority ($500) — 24/7 emergency response, immediate supplier outreach, same-day shipping coordination.
Deep / Legacy Research ($1,000) — Obsolete or extremely hard-to-find components requiring global network search.

FAA Form 8130-3 is an Airworthiness Approval Tag certifying a part meets FAA standards. We verify trace — including 8130-3, EASA Form 1, or operator release — before confirming any part. We do not present ghost listings or unverified stock.

A ghost listing is a part that appears in a supplier's system but is not physically in stock. Ghost listings cause dangerous AOG delays. Red Phone AOG physically confirms stock with the supplier before presenting any option to you.

Aircraft make/model, tail number, part number (if known), part description, your location, and urgency level. Include condition requirements (new, overhauled, serviceable) and any approved alternates for the fastest response.

No. Red Phone AOG is a sourcing and verification consulting service. We locate, verify, and present qualified options. You purchase directly from the vendor. You stay in control of the transaction — we handle the search.

Gulfstream · Bombardier Global & Challenger · Learjet · Dassault Falcon · Cessna Citation (all series) · Embraer Phenom & Praetor · Hawker · Beechjet · Beechcraft King Air · Pilatus PC-12 · HondaJet · Legacy and out-of-production aircraft via our Deep Research tier.

Yes. Our Deep/Legacy Research tier ($1,000) covers components for aircraft no longer in production — older Learjet, Hawker, Falcon, Citation variants. We tap salvage yards, teardown programs, and global surplus networks unavailable through standard channels.

Flight departments on retainer receive fee-waived sourcing support. If you have a retainer arrangement with AOne Parts and Logistics LLC, enter your PIN on the request form and consulting fees are waived automatically.

PartsBase is a parts marketplace — it lists what suppliers say they have. Red Phone AOG is a sourcing consultant — we call those suppliers, confirm physical stock on the shelf, verify trace documentation (8130-3 / EASA Form 1), and present you with only confirmed options. If you've ever chased a PartsBase listing that turned out to be a ghost, you know why that distinction matters when your aircraft is AOG. We use PartsBase and other databases as one of many tools — but we never stop at the listing.

ILS (Inventory Locator Service) is one of the industry's largest parts databases — thousands of suppliers list inventory there. The problem: ILS shows you what suppliers claim to have. Red Phone AOG picks up the phone and confirms it. We cross-reference ILS, PartsBase, and direct supplier contacts simultaneously, then physically verify stock, condition, and trace before we ever call you back. If you've gotten a 'yes we have it' from ILS and showed up to find a warehouse with nothing on the shelf, that's the gap we close.

Aviall is a premier OEM distributor and often the first call for Citation, King Air, and other Textron/Beechcraft parts. But Aviall is one supplier — a deep one, but one. When Aviall is out or quoting days-out lead time and your aircraft is AOG right now, Red Phone AOG moves through 379+ alternative suppliers: authorized distributors, independent MROs, surplus houses, rotable exchanges, and international sources. We find who physically has it today, not who can order it for next week.

All of them. Textron Aviation's Citation family is one of the broadest in business aviation and we carry suppliers for every series: Citation CJ1 · CJ2 · CJ3 · CJ4 · M2 · XLS / XLS+ · Sovereign / Sovereign+ · Latitude · Longitude / Ascend · Citation X · Citation 550 · Citation 560 · Citation 650 (III / VI / VII). Textron / Cessna OEM parts coordination, alternate approved source identification, and surplus sourcing are all covered. If you're on a Textron product and you're AOG, one call handles it.
