Buying aircraft parts by part number
The manufacturer part number (MPN) is the only reliable way to match a used aviation part to your aircraft — titles and photos vary between sellers, part numbers don't. Before buying, confirm the number against your aircraft's illustrated parts catalog, check whether the part ships with airworthiness paperwork (an FAA 8130-3 form or a maintenance-release tag), and note the difference between OEM parts and FAA-PMA approved replacements. Prices shown are asking prices from US eBay sellers; checkout happens on eBay.
