Manufacturer	Collins Aerospace

Advanced Exchange ships a serviceable unit before the core is returned. Future Exchange begins after receipt and evaluation of the core and does not require a deposit. Repair retains the original serial number and starts with inspection and quotation.

Advanced Exchange

What happens: You receive a serviceable unit first. Your core goes back afterward.
Pay now: Full SV price plus core deposit.
Core: Return within 15 calendar days. Repairable (not BER) — deposit refunded. Missing or BER — deposit stays.
Time: Typically 2–3 weeks. Warranty 3 months. Released on EASA Form 1 or FAA 8130-3.

Future Exchange

What happens: You send the core first. After we confirm it is repairable, we ship the serviceable replacement.
Pay now: Net exchange price only. No deposit.
Core: Must be repairable (not BER). Same or superseded P/N, data plate on.
Time: Typically 3–4 weeks. Warranty 3 months. Released on EASA Form 1 or FAA 8130-3.

Repair

Serial: Yours stays. No swap unit — that is Exchange.
Shop: We inspect, quote, then repair. Accept the repair quote and the evaluation fee already paid is deducted. Decline or BER — unit returns as-is; evaluation fee stays.
Time: Typically 2–6 weeks after you approve the quote, parts depending. Warranty 3 months. Released on EASA Form 1 or FAA 8130-3.

Return the core in equivalent packaging, with removal data and a non-incident statement where you have them. Late, incomplete, or rejected-core terms are on the quote.
