A Boeing SPEEA strike cannot begin before Oct. 7, 2026. The Professional and Technical contracts between Boeing and SPEEA (IFPTE Local 2001) expire Oct. 6, and members already authorized a strike on Aug. 21, when they rejected Boeing's first offer. Boeing has since made a final offer: a 10% guaranteed raise on Oct. 16, 2026, 4% at the March 2027 annual review, and 6% wage pools in 2028, 2029 and 2030 with 4% guaranteed each year. SPEEA's negotiating team recommends a yes vote.
For suppliers, the wage table matters less than a practical question. A lot of routine supplier quality work ends with a Boeing decision: a disposition on nonconforming hardware, an answer on a substitution request, a verification step before a shipment moves. If a strike thinned out the Boeing staff who make those decisions, what happens to parts sitting in your MRB cage?
This piece covers what Boeing's published supplier requirements say, what they do not say, and what a tier-1 or tier-2 supplier can do in the roughly three weeks before the contracts expire. One limit up front: which Boeing jobs SPEEA represents is set out in Appendix B of each contract, which we have not reviewed. Nothing here assumes that any specific supplier quality, liaison engineering or MRB role would be affected. We also found no public Boeing guidance to suppliers about a SPEEA strike.
Where do the talks stand?
On Aug. 21, 2026, SPEEA's Professional unit rejected Boeing's first offer 7,238 to 4,027 (64%), and the Technical unit rejected it 2,795 to 1,094 (72%), with 92% turnout. The same vote authorized a strike, with 88% support in the Prof unit and 89% in the Tech unit, according to NW Labor Press.
The Lynnwood Times puts the Prof unit at 12,696 engineers and scientists and the Tech unit at 3,959 designers, analysts, specialists and technicians. Most work in the Puget Sound region. NW Labor Press reports about 200 members in Gresham, Oregon and about 100 each in California and Utah.
SPEEA's post announcing the final offer is dated Sept. 11; the Lynnwood Times and the Everett Post reported it on Sept. 12. Beyond the raises, the offer includes:
-
Additional money for wage compression and for employees with low Compa-Ratios
-
Revised work-from-home language
-
Overtime limits for the Prof unit
-
A new process for sharing Boeing's future workforce needs with the union
Boeing vice president Ben Nimmergut told the Lynnwood Times the offer "addresses the top priorities identified by our employees." SPEEA's Bargaining Unit Councils get the details on Thursday, Sept. 17. As of Sept. 12, the membership vote date was listed as to be announced.
If members ratify, most of this article becomes a contingency plan you did not need. But a first offer was voted down by wide margins, the strike authorization is already in place, and the contracts expire Oct. 6. Suppliers have about three weeks, and the work described below is useful housekeeping either way.
Which supplier decisions depend on Boeing?
Dispositions on nonconforming hardware
The core document is Boeing's X31764, Quality Purchasing Data Requirements for BCA and BGS (Rev 5, January 2026). As its indexed text describes, a supplier may not apply a use-as-is or repair disposition to nonconforming product for Boeing commercial airplanes unless Boeing has delegated Material Review Authority (MRA) to that supplier under D-13709-4 or D-13709-5.
Use-as-is and repair are the two dispositions that accept a part that departs from the design, rather than bringing it back to drawing or scrapping it. Those are the decisions Boeing keeps control of. A supplier without delegated MRA, or with a nonconformance outside the scope of its delegation, sends the item to Boeing for disposition under D6-84111.
That produces two groups of suppliers:
-
Suppliers with delegated MRA can disposition within the scope of their delegation. Anything outside that scope still goes to Boeing.
-
Suppliers without delegated MRA rely on Boeing to disposition every use-as-is or repair case.
We could not parse the X31764 PDF text directly, so this summary comes from the indexed document. Before you build a plan around it, check the clause wording and numbering against the current revision and the quality clauses on your own purchase orders.
Material substitutions and deviations
Boeing's supplier quality documents also bar unauthorized material substitutions, defined as any deviation from the engineering definition of a raw material. The base quality system document is D6-82479, Boeing Quality Management System Requirements for Suppliers (Rev K). In practice, if a mill certificate, alloy or temper will not match the engineering definition, the supplier needs authorization before shipping, not a note in the traveler.
First articles and verification steps
Many purchase orders also include steps where the customer reviews or verifies before product ships, such as first article results or source inspection. Whether those steps apply to a given part, and who at Boeing performs them, depends on your purchase order and its flowed-down quality clauses. Our research did not establish which of those steps would be staffed by SPEEA-represented employees, so treat each one as a question for your Boeing contacts, not a known gap.
What keeps running during a strike?
Your obligations do not pause because the customer's staffing changes. Three requirements matter most here.
Escape reporting clocks. Under the same Boeing requirement set (indexed text, same caveat as above), a supplier must notify Boeing within 3 business days of discovering a potential or known nonconformance escape, and submit full information through Boeing's supplier system within 10 business days of confirming the escape. Nothing in those requirements stops the clock during a labor dispute.
The substitution ban. An unauthorized material substitution is still unauthorized if nobody is available to authorize it.
The limits of your delegation. A strike does not widen delegated MRA. If a disposition sits outside your scope, it goes to Boeing under D6-84111. A strike is not a reason to ship a part on your own use-as-is or repair call. The risk if you do: a delivered part that later counts as an escape, with the reporting clocks above starting from discovery.
One structural change since the last major dispute: Boeing closed its acquisition of Spirit AeroSystems on Dec. 8, 2025. Spirit's 737 fuselage work in Wichita, its 767, 777 and 787 structures work, and about 15,000 employees came in-house, while Airbus took Spirit's Airbus work packages. Manufacturing Dive put the deal at about $4.7 billion in equity, or $8.3 billion including debt. Suppliers that used to sell to Spirit on those programs now sell into Boeing, which may change which Boeing quality organization handles their dispositions.
What should a tier-1 or tier-2 do this month?
None of these steps depend on how the vote goes.
-
Inventory everything waiting on Boeing. List open dispositions submitted under D6-84111, pending substitution or deviation requests, and any other items waiting on a Boeing answer. Sort by age, part number, program and the dollar value of held hardware.
-
Push what can close before Oct. 6. Many old requests are stuck for lack of a follow-up. Resubmit missing data, answer open questions and ask for a decision date on anything that blocks a shipment in October.
-
Check the scope of any delegated MRA. Pull your D-13709-4 or D-13709-5 delegation and confirm which part families, processes and defect types it covers. Brief your MRB so nobody mistakes a gap in Boeing's staffing for an expansion of your authority.
-
Plan October and November first articles. Identify new parts, changed processes, new sub-tier sources and production breaks that will trigger a first article or a partial first article. Pull forward the ones you can.
-
Get contingency contacts in writing. Ask your Boeing buyer and supplier quality contact who will handle your dispositions, requests and verification steps if the Oct. 6 date passes without a contract. Ask for names or mailboxes, not reassurance.
-
Flow it down. Your sub-tiers need to know that escape notification timelines and the substitution ban still apply, and that a slower answer from Boeing does not authorize them to self-disposition either.
What if parts are made but not accepted?
The best recent example comes from a different strike. The IAM machinists' strike at Boeing began Sept. 13, 2024. Spirit AeroSystems, then an independent supplier, disclosed in an 8-K filing that it would put about 700 employees on the 767 and 777 programs on a 21-day furlough starting Oct. 28, 2024, citing "a significant inventory buffer." Spirit also froze hiring, restricted travel and overtime, and warned of layoffs if the strike ran past November.
That was a production strike, not an engineering one, so the mechanism was different. The lesson for a supplier still applies: when the customer cannot absorb parts, finished goods pile up, and the constraint shows up as floor space and labor before it shows up in the P&L. If a SPEEA strike slowed dispositions and approvals, the effect would be similar for held hardware: parts that are built but cannot ship.
Questions to answer now:
-
Storage. How many weeks of held or finished Boeing hardware can you physically store, with the handling and preservation the parts require?
-
Cash. How much working capital sits in WIP and finished goods that cannot be invoiced until Boeing accepts it?
-
Contract terms. What do your purchase order terms say about buyer-caused delays, schedule relief and payment on held product? Read them before October, not during a dispute.
-
Labor. If a line stalls, will you move people to other customers' work, cut overtime, or furlough? Decide the thresholds ahead of time.
To size the exposure, use our downtime cost calculator. It separates the contribution you lose while a line is idle from the incremental cost of recovering later (overtime, expediting, requalification), which is the split a finance team will ask for.
What do ODA and certification exposure mean for delivery rates?
Boeing performs certain FAA functions through an Organization Designation Authorization. Under 14 CFR 183.41(a), an ODA lets a company perform functions "related to engineering, manufacturing, operations, airworthiness, or maintenance" on the FAA's behalf. Reports on the dispute say some SPEEA members work in Boeing's ODA unit. They should not be confused with Designated Engineering Representatives, which are a different FAA designee type.
The 2000 precedent shows the scale of disruption an engineering strike can cause. SPEEA's strike began Feb. 9, 2000 and lasted 40 days. About 17,000 workers walked out, the largest white-collar strike in U.S. history at the time. Boeing missed about three dozen deliveries, and members walked out of scheduled FAA meetings, KNKX reported.
For current programs, AVweb and other trade coverage report that a strike could slow certification of the 737-10 and 777-9. TechTimes reported that as of July 28, 2026, DAR 4 on the 737-10 was about 60% complete and System Safety Assessments were about 32% complete. Its headline goes further than the facts support: a strike does not automatically halt certification. For suppliers on those programs, the risk is schedule uncertainty on new-model demand, not a forecast we can put a number on.
What is Boeing's contingency plan?
Boeing told AVweb on Aug. 27, 2026: "we're implementing our contingency planning which will leverage a wide range of qualified resources with a continued emphasis on safety and quality." The company has also posted contract engineering and technical jobs.
That statement does not say who would disposition a given supplier's nonconformance, answer a substitution request or perform a verification step. For suppliers, the useful follow-up is specific: for your commodity and your part numbers, who holds the signature authority after Oct. 6, and how will you reach them? Do not assume someone does until Boeing tells you in writing.
