Federal obligations in other aircraft parts and auxiliary equipment manufacturing (NAICS 336413)

Parts, not complete aircraft

NAICS 336413 covers establishments that manufacture aircraft parts and auxiliary equipment other than engines. On USAspending.gov the code tags contract awards classified that way: structures, landing gear, auxiliary systems, and similar hardware that is not the complete airplane and not the engine. Spare buys, repairables, and production of components all can carry this tag.

Complete aircraft manufacturing is 336411. Engine manufacturing is 336412. A sustainment program can generate a long tail of 336413 actions while the airframe buy sits on 336411. The $91.3 billion figure is only the parts-and-auxiliary slice. Treating it as all aviation hardware misses airframes and engines.

Why 148,816 awards sit under $91.3 billion

This is the high-volume aerospace manufacturing code in the set: many purchase orders and delivery orders for spares and components, each an award record in USAspending. The 148,816 count is not 148,816 unique part numbers or unique aircraft. It is how often agencies recorded a contract action tagged 336413. Dollars per record are typically smaller than on complete-airframe awards, which is why the obligation total is lower than 336411 even though the award count is higher.

Obligations are commitments on those actions. Outlays follow deliveries and invoices. This packet has no fiscal-year split. Quote $91,287,085,277.51 as USAspending contract obligations coded to NAICS 336413.

How to read a spare-parts industry table

A parts code will look “busy” in award count and still be smaller in dollars than a platform code. That is expected. It does not mean parts are unimportant; it means the contracting pattern is many actions. Open the industry page before inferring a small or large vendor set. High award counts can still concentrate dollars in a few manufacturers.

Parts codes are where sustainment lives in the award file. NAICS 336413 shows $91,287,085,277.51 in USAspending obligations on 148,816 awards, a long tail of delivery orders for other aircraft parts and auxiliary equipment. Complete airframes stay on 336411. Engines stay on 336412. Missile parts stay on 336419. The 148,816 figure is the loudest volume signal in the aerospace manufacturing group in this set, and it is still not a part-number census. Cite dollars and award count together so no one hears a small prime-lot story. Cite USAspending. Cite obligations, not outlays. Assistance is generally excluded. The industry page is the working list of those 148,816 rows.

What 336413 excludes

Assistance awards often lack NAICS and are outside this total. Air transportation support services (488190) are services, not parts manufacturing. Guided-missile parts are 336419, not aircraft parts. Search and navigation instruments are 334511. Those neighboring pages are separate rollups.

SpendingVault aggregates USAspending.gov contract data. The dollar total and the 148,816 award count can change after corrections. The live industry page is the working table.

Using the aircraft-parts industry page

Open the OTHER AIRCRAFT PARTS AND AUXILIARY EQUIPMENT MANUFACTURING industry page for the award list under the headline. Compare 336413 with 336411 and 336412 on All industries. Cite obligations, not outlays, and keep the 148,816 award count so the high-volume parts pattern is not mistaken for a small set of airframe lots.

Citing a high-volume parts code

Cite $91,287,085,277.51 in USAspending obligations on 148,816 awards tagged NAICS 336413, other aircraft parts and auxiliary equipment manufacturing. Put the award count next to the dollars. Without 148,816, the total looks like a small set of airframe lots; with it, the spare-parts pattern is visible.

Do not borrow airframe or engine totals from other pages. Those facts are not in this packet. The 148,816 records are actions, not part numbers. Outlays are not provided here. Assistance is generally excluded. The industry page is the working list if you need to see how the long tail of orders is distributed.

Spare-parts contracting is where award counts explode. The $91,287,085,277.51 total on 148,816 awards is the clearest parts-versus-platform contrast in this aerospace set: more rows, fewer dollars than complete-airframe manufacturing. Each delivery order is a record. A nut-and-bolt buy and a landing-gear lot can share the code if both are tagged 336413.

Auxiliary equipment in the NAICS title is not a license to include engines. Engines are 336412. Complete aircraft are 336411. Missile parts are 336419. Keep those borders. Quote USAspending, obligations, and 148,816 awards together so no one mistakes this page for a small set of airframe primes. Outlays remain unpublished in this packet.

Questions

How much is obligated on NAICS 336413 aircraft parts?

USAspending.gov contract awards coded NAICS 336413 show $91,287,085,277.51 in obligations across 148,816 awards. That total is obligations, not outlays, for other aircraft parts and auxiliary equipment manufacturing. USAspending.gov records the amount as contract obligations, not outlays, on awards tagged NAICS 336413.

Why are there more awards than in complete aircraft manufacturing?

Parts and spares generate many delivery orders. Complete aircraft (336411) has fewer records and a larger dollar total in this dataset. The 148,816 figure counts award records tagged 336413, not airframes or part numbers. The packet total is $91,287,085,277.51 across 148,816 awards; assistance awards often have no NAICS and stay outside the industry rollup.

Are aircraft engines included in 336413?

No. Aircraft engine and engine parts manufacturing is NAICS 336412. This table’s $91,287,085,277.51 is other parts and auxiliary equipment, not engines. Treat the 148,816 figure as an award-record count, including orders and modifications, not as a physical inventory of products or sites.

Does this include complete airplanes?

No. Complete aircraft manufacturing is NAICS 336411. 336413 is parts and auxiliary equipment only. This guide does not add a fiscal-year split. Quote the live industry page if you need the current award list under OTHER AIRCRAFT PARTS AND AUXILIARY EQUIPMENT MANUFACTURING.
