Same numbers as the chart, straight from BLS. Dates are the first of each period, the way BLS reports them.
Aircraft rose 2.7% over the last 12 months, but 2 of its main inputs rose faster: aluminum mill shapes +25.2%, wages and salaries, aircraft mfg +3.1%. That cost pressure may still pass through to prices.

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 — Aircraft Manufacturing (BLS series PCU336411336411), published by BLS. Base Period: the index value published for September 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.]
Indexes new-build aircraft directly. Does not cover spare parts, which have no matching government series and price from a composite instead.
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.
New aircraft are escalated with a labor and inflation formula, not a manufacturing PPI: 65% Employment Cost Index (manufacturing, CIU2013000000000I) plus 35% CPI-U (CUUR0000SA0), measured against base-year values and applied at delivery. Spare parts have no series built for them, so price them from a weighted input composite instead.
Escalake tracks US PPI — Aircraft Manufacturing, applies your formula, and gives both sides a number they can confirm, no spreadsheet required.
