What 63506083-4 is
An air turbine engine starter, described on RFQs as "AIR TURBINE STARTER ATS" and "STARTER". Several suppliers quoting it identified the application as a LEAP-1A engine — that is their statement about what it fits, not ours, and effectivity is something to confirm against your own configuration rather than take from a quote. An air turbine starter uses bleed air to spin the engine to light-off speed. No manufacturer was recorded on any RFQ line and none was stated in a labelled field of any quote, so this page names none. A catalogue record suggests one; that source is not reliable enough to publish from.
Condition guidance for 63506083-4
New is the only published condition, and its range is the widest on this site: $280,000 to $940,000, median $700,000, from 14 quotes across 9 suppliers. **Read that width carefully before you use it.** A high more than three times the low is not normal, and it is not thin data — 9 independent suppliers is among the deepest evidence we hold for any part. A spread that wide on genuinely new units usually means the quotes are not describing the same thing: different build standards, different included accessories, factory-new against long-held new-surplus stock, or a quantity break at one end and a single unit at the other. The median sits well above the midpoint of the range, which says most suppliers cluster nearer the top and a small number are quoting substantially less. Treat the median as the honest centre and treat anything near $280,000 as a question rather than a find. Ask what build standard the unit is, what comes with it, and how long it has been in stock. Overhauled was quoted but is not shown: 3 quotes from only 2 suppliers, which is below the three-supplier minimum this site requires. That threshold exists partly for a reason worth knowing — with three quotes from two suppliers, whoever holds two of the numbers could work out the third from our published range. Request overhauled directly and we will source it.
Availability is mixed. Of the 19 quotes that stated a lead time, 5 offered stock, but the median was 11 days and the 75th percentile 30 days. A quarter of quotes were effectively immediate and a quarter were a month out, which is consistent with a part where some suppliers hold stock and others are sourcing to order. Demand is light — 2 RFQ lines across 2 requests, neither flagged AOG. The pricing depth here comes from how many suppliers answered, not from how often it has been asked. One supplier offered this part on an exchange basis. We publish exchange figures nowhere and we do not flag exchange availability on a single supplier's say-so, because one supplier's exchange offer is that supplier's commercial position rather than a market fact. It is still worth asking your own suppliers whether exchange is available: it usually costs less than outright because you return a core. No alternate part numbers were found — the DLA PUB LOG returned no NSN cross-reference for this part number.
Frequently asked
Because the quotes genuinely differ that much, not because the data is thin — this range rests on 14 quotes from 9 suppliers, which is more evidence than most parts on this site have. A $660,000 spread on new units almost always means the units are not equivalent: build standard, what is included, and how long stock has been held all move a starter's price. Use the median as the reference and treat the bottom of the range as something to ask about.
Almost certainly, but we are not going to publish a number for it. Only 2 suppliers quoted overhauled, and a range from two suppliers is not a market — it is also close enough to individual quotes that publishing it would expose them. Ask and we will source it live.
It depends on the supplier. 5 of the 19 quotes stating a lead time offered stock, but the median was 11 days and the 75th percentile 30 days. If you have a date to hit, say so up front.
Yes, on a part of this value. Exchange typically runs below outright because you send back a repairable core. We do not publish exchange prices, so ask your suppliers for both bases and compare.
For a new unit, often a manufacturer's Certificate of Conformance rather than an 8130-3, which is normal and not a warning sign. Our [8130-3 guide](/guides/8130-3-verification) explains when to expect which document, and when its absence is a real question.
Prices are aggregated from quotes our sourcing desk requested from suppliers — never a single supplier’s price. Each is parsed automatically and spot-checked by a human when we quote it to a buyer; not every quote in this range has had that second look. Our methodology explains how we check them.
