Index lookup · PCU33641-33641-
Producer Price Index industry data for aerospace product and parts manufacturing (NAICS 33641), an aggregate spanning aircraft, aircraft engines, and other aerospace parts manufacturing together, broader than PCU336411 (Aircraft Manufacturing) or PCU336412 (Aircraft Engine and Engine Parts Manufacturing). Index base: June 1985 = 100.

Used as a portfolio-level benchmark in a diversified aerospace supply contract spanning airframes, engines, and parts together rather than isolating one component type. A dispute over a specific component should still cite PCU336411 (Aircraft Manufacturing) or PCU336412 (Aircraft Engine and Engine Parts Manufacturing) instead, since this aggregate blends them.
A starting point citing this series by name and code. Replace the bracketed terms with your contract's actual scope before use.
The [affected portion] of the Contract Price shall be adjusted using US PPI — Aerospace Product and Parts Manufacturing (NAICS 33641) (BLS series PCU33641-33641-), published by BLS. Base Period: the index value published for August 2026 (or the month of contract signing, if different) is the Base Value. Adjustment: at each Adjustment Date, the Current Value is the most recently published three-month average of the index (the Averaging Window). The Escalation Factor equals Current Value divided by Base Value. Cap: the Escalation Factor applied under this clause shall not exceed 1.10 or fall below 0.90 (a 10% cap and floor) in any single Adjustment Date, regardless of the index's actual movement. [Replace bracketed terms with your contract's actual affected-portion definition and adjustment-date schedule before use. This is a drafting starting point, not legal advice.]

Split defense contracts into aircraft, naval, land systems, missiles, and small arms. Aircraft (PCU336411336411), naval systems (PCU336611336611), and small arms/ordnance manufacturing (PCU33299T33299T) have real, published US government price indices. Land systems and missiles do not, confirmed by direct check against the BLS API. Build those two from a weighted input composite instead.
