Crossroads of American Industry
Technical Translation Services in Indianapolis, IN
Techniwords translates the engineering and regulatory documentation that runs three of Indianapolis's defining industries: turbine engine programs at Rolls-Royce's Indianapolis facility, pharmaceutical manufacturing and clinical documentation at Eli Lilly's global headquarters and LEAP campus, and automotive assembly documentation for Subaru of Indiana, the only Subaru production plant outside Japan. Our certified technical translators work in German, French, and Japanese for the specific programs these companies run.
Rolls-Royce Indianapolis works with European partners including MTU Aero Engines and Safran. Engine maintenance manuals, airworthiness directives, and certification packages move between English, German, and French on every major program.
Eli Lilly's global headquarters and its expanding LEAP manufacturing campus in Lebanon, IN generate batch records, validation protocols, regulatory submissions, and labeling documentation for markets in over 100 countries.
Subaru of Indiana in Lafayette is the only Subaru plant outside Japan. Engineering change orders, quality management documentation, and supplier specifications flow continuously between Indiana and Subaru engineering centers in Gunma Prefecture.
Rolls-Royce Indianapolis and the Allison Legacy
Rolls-Royce's Indianapolis facility traces its lineage to Allison Engineering, founded in 1915 and acquired by General Motors in 1929. Allison produced the liquid-cooled V-1710 engines that powered P-38, P-40, and P-51 Mustangs in World War II, and the company's turbine work afterward established Indianapolis as a center of American gas turbine engineering. Rolls-Royce acquired the Allison Gas Turbine Division from GM in 1995 and has operated the Indianapolis campus as a primary manufacturing and engineering site since then, producing the AE family of regional aircraft engines, the T56 turboprop for the C-130 Hercules, and components for the Trent civil turbofan family.
The Indianapolis site sits at the intersection of Rolls-Royce's British engineering heritage and its American military and civil aviation programs. That position creates constant documentation translation needs in both directions. Technical collaboration with Rolls-Royce's engineering centers in Derby, England, involves English-language documents throughout, but the supply chain connecting Indianapolis to European component manufacturers runs through German, French, and occasionally Italian engineering documentation. Our aerospace translation team handles this work with translators who understand the specific vocabulary of gas turbine engineering, from compressor stage nomenclature and turbine blade coating specifications to airworthiness directive compliance documentation.
The motorsports side of Indianapolis engineering also generates translation work. The Indianapolis Motor Speedway draws teams from Europe, Japan, and South America, and the technical exchange between IndyCar teams, their international parent organizations, and their suppliers produces engineering documentation in multiple languages. Component development reports, supplier qualification packages, and aerodynamic simulation data all travel across language boundaries in the racing community that operates in and around Indianapolis.
Aerospace Documentation: Engines, Certification, and MRO
Aerospace documentation follows a regulatory framework that is more specific and more demanding than almost any other industry. The Federal Aviation Administration regulates every document type that touches an airworthy component, from type certificates and supplemental type certificates to approved maintenance manuals and airworthiness directives. The European Union Aviation Safety Agency applies parallel requirements for aircraft operated in Europe. When an Indianapolis-produced engine goes into service on a regional aircraft flying in Japan, Germany, or Brazil, its maintenance documentation must meet the airworthiness requirements of the applicable civil aviation authority in that country, which usually means it must be translated into the local language.
The table below shows the document types we most commonly translate for Indianapolis-area aerospace clients and the language combinations those documents travel in:
| Document type | Applicable authority | Languages most requested |
|---|---|---|
| Engine maintenance manuals and overhaul manuals | FAA / EASA / JCAB | German, French, Japanese |
| Airworthiness directives and mandatory service bulletins | FAA (AD) / EASA (AD) | German, French, Spanish, Japanese |
| Component maintenance manuals | FAA / EASA | German, French, Japanese |
| Material specifications and process specifications | OEM and prime contractors | German, French |
| Type certificate data sheets and conformity documentation | FAA / EASA | German, French |
| Illustrated parts catalogs | OEM distribution | German, French, Japanese, Spanish |
Regulatory submissions for EASA approval of an FAA-certified component are a specialized category. Our team translates regulatory submission documentation with the structural consistency EASA reviewers expect, matching the terminology conventions in EASA certification specifications so that what reviewers read aligns with how the FAA-side documentation is described.
Eli Lilly and the Indianapolis Pharmaceutical Hub
Eli Lilly and Company has operated from downtown Indianapolis since its founding in 1876, and the city remains the company's global headquarters. Lilly employs more than 10,000 people in the Indianapolis metropolitan area and operates one of the most active pharmaceutical manufacturing and research presences in the United States. Its existing facilities in Indianapolis handle API manufacturing, finished drug product manufacturing, and packaging for markets around the world. The LEAP district, a new manufacturing campus in Lebanon, Indiana, northwest of Indianapolis, adds significant capacity for both small-molecule and biologic drug manufacturing as the company's pipeline advances through late-stage clinical development.
Pharmaceutical manufacturing documentation is among the most regulated content we translate. Every batch record, every validation protocol, every change control document, and every standard operating procedure at a GMP-compliant facility operates under the oversight of FDA, the European Medicines Agency, or the regulatory authority of whichever country receives the finished product. Translation errors in manufacturing documentation carry consequences that range from regulatory noncompliance findings to product recalls, which is why our pharmaceutical manufacturing translation practice applies ISO 17100-compliant processes with two independent linguists on every document, not a translation followed by a light edit.
Lilly's global commercial operations require product labeling, patient information leaflets, prescribing information, and marketing authorization documentation in the official languages of each market. For new molecular entities and biologics entering multiple markets simultaneously, that typically means translating the same core dossier into 15 to 20 languages as part of the regulatory submission package. We manage those multi-language rollouts with project infrastructure that tracks each language pair independently and delivers all of them to a shared review schedule.
GMP Manufacturing Documentation: What We Translate
The following categories of GMP and pharmaceutical documentation represent the most common requests from Indianapolis-area pharmaceutical clients:
- Batch manufacturing records and batch release documentation
- Process validation protocols and reports (IQ, OQ, PQ, PPQ)
- Analytical method validation protocols and transfer documentation
- Standard operating procedures for GMP manufacturing and quality control
- Master production and control records
- Stability study protocols and periodic stability reports
- Regulatory submission modules (CTD format, Module 3 in particular)
- Product labeling, package inserts, and patient information leaflets
- Drug master files submitted to FDA and foreign regulatory authorities
- Annual product reviews and continued process verification reports
The LEAP district in Lebanon, Indiana is one of the largest pharmaceutical manufacturing investments in US history. As Lilly's biologic and small-molecule pipeline advances, the documentation generated at LEAP will need to travel to regulatory authorities, contract manufacturing partners, and commercial distributors in markets that require local-language documentation. The translation workload is built into the LEAP business case from the start.
Subaru of Indiana: The Only Subaru Plant Outside Japan
Subaru of Indiana Automotive, located in Lafayette about 65 miles northwest of Indianapolis, has produced Subaru vehicles since 1989. The Lafayette plant currently assembles the Outback, Ascent, and Legacy, making it the production source for the majority of the Subaru models sold in North America. It is the only Subaru manufacturing facility outside of Japan, a distinction that creates a translation environment unlike any other automotive plant in the United States.
Subaru's production and quality engineering functions are headquartered in Gunma Prefecture, Japan, at the Yajima Plant and the Subaru Technical Research Center. Every engineering standard, every quality assurance procedure, every kaizen improvement proposal, and every design change that affects the Lafayette production line originates in Japanese at a Gunma engineering team. Those documents need to be in English before Lafayette engineers can implement them. Every quality problem, production deviation, or supplier non-conformance report that Lafayette generates needs to travel back to Japan in Japanese for Subaru's engineering review.
Our automotive translation practice handles this bidirectional flow, with Japanese translators who know Subaru's quality vocabulary and the Toyota Production System concepts that inform how Subaru engineers think and write about manufacturing problems. The Subaru Symmetrical All-Wheel Drive system, the BOXER engine configuration, and the EyeSight driver assistance system all have their own technical vocabularies in Japanese that require translators who have encountered those terms in context, not only in a dictionary.
German for Aerospace and Precision Manufacturing Supply Chains
Germany sits near the center of every major aerospace program that Rolls-Royce Indianapolis participates in. MTU Aero Engines in Munich is a long-standing partner on the V2500 engine program and a collaborator on future development programs. German aerospace suppliers including Liebherr Aerospace (landing systems, air management), ZF Friedrichshafen (actuation systems), and Diehl Aviation (cabin systems) supply components to programs that flow through Indianapolis. German precision manufacturing suppliers also serve the broader Indiana industrial base, providing components to automotive tier suppliers and industrial equipment manufacturers.
Our German technical translation practice covers the documentation that moves through these relationships: material and process specifications written against German industrial standards (DIN norms, VDW standards), component qualification packages, engineering calculation notes, flight test data reports, and the certification documentation that EASA accepts from its German-accredited design organizations. German engineering documentation tends to be structured in specific ways that reflect how German standards are written, and translators who have only encountered German in non-technical contexts often produce English that is grammatically acceptable but structurally unfamiliar to aerospace engineers who know what a German calculation note normally looks like.
French for Safran and European Aerospace Programs
Safran, the French aerospace and defense group, is one of the most significant partners in programs that connect to Indianapolis aerospace. CFM International, the 50-50 joint venture between Safran Aircraft Engines and GE Aerospace, produces the CFM56 and LEAP engine families that together power more than half of all commercial aircraft in service worldwide. While GE's turbine manufacturing operations are centered in Ohio and North Carolina, the engineering exchange between GE and Safran's Paris-area engineering teams produces French-language documentation that Indianapolis-area aerospace engineers encounter regularly.
Our French technical translation team handles aerospace documentation that originates at Safran, Airbus, Thales, and the French defense procurement organization DGA. That covers technical design notes written in French against French standard methodology, airworthiness certification documentation submitted to EASA through France's DGAC, component specifications for Airbus aircraft that supply the Indianapolis-connected engine programs, and collaborative engineering reports from joint development teams where the working language is French. French aerospace documentation has structural conventions and vocabulary preferences that reflect the French grandes ecoles engineering tradition, and translators who understand those conventions produce cleaner, more readable English.
Japanese Technical Translation for Subaru Suppliers
The Subaru Lafayette plant draws on a supplier network that includes both American and Japanese Tier 1 manufacturers. Japanese suppliers with operations in Indiana and neighboring states supply precision components, electronic systems, and body parts to the Lafayette assembly line under the same quality standards that apply at Subaru's Japanese plants. Engineering documentation from those suppliers arrives in Japanese. Our Japanese technical translation team handles supplier quality documentation, component specifications, initial quality studies, and the engineering reports that Subaru's Lafayette quality team needs to review and accept before a new component enters production.
The Lafayette plant's relationship with Subaru's Japanese engineering centers also generates steady demand for translation of quality management documentation. Problem-solving reports using the A3 format, quality circle activity reports, and kaizen event summaries all carry vocabulary from Toyota Production System practice that has specific Japanese meaning and specific English equivalents used in lean manufacturing contexts. Translators who have only encountered this content in a Japanese-language course will miss the specific English-lean vocabulary that the Lafayette plant's American engineers expect to see in a properly translated A3 report.
Need a Technical Translator in Indianapolis?
Indianapolis engineering teams typically need translators who can work accurately in at least one of three specialized domains: aerospace certification and maintenance documentation, pharmaceutical GMP and regulatory documentation, or Japanese automotive quality management. These are not domains where a general translator can perform to professional standard: the regulatory frameworks, the document structures, and the terminology are all industry-specific and require translators who have worked in those industries.

Indianapolis Technical Translation: Questions We Hear
What aerospace documentation can you translate for Rolls-Royce and their suppliers?
We translate engine maintenance manuals, overhaul manuals, airworthiness directives, component maintenance manuals, illustrated parts catalogs, material and process specifications, type certificate data sheets, and EASA regulatory submissions. The language pairs we handle most often for Indianapolis aerospace clients are German-English and French-English, covering documentation from MTU Aero Engines, Safran, Airbus, and other European partners. Our aerospace translators hold engineering or aviation credentials in addition to their translation qualifications, so they read engine documentation as practitioners, not as linguists working from a glossary.
Do you translate FDA regulatory submissions and GMP documentation for pharmaceutical manufacturers?
Yes. We translate batch records, validation protocols, standard operating procedures, master production and control records, CTD regulatory submissions, product labeling, package inserts, drug master files, and stability study documentation. For Eli Lilly and its LEAP campus, that includes both small-molecule and biologic manufacturing documentation. All pharmaceutical translation goes through our ISO 17100-compliant two-linguist process: a subject-matter-expert translator followed by an independent reviewer with equivalent credentials, no exceptions.
Can you handle Japanese-English translation for Subaru of Indiana and its suppliers?
Yes. We translate engineering change orders, quality management documentation, A3 problem-solving reports, kaizen activity summaries, supplier qualification packages, component specifications, and production engineering procedures between English and Japanese for the Subaru Lafayette plant and the supplier network around it. Our Japanese translators understand Toyota Production System vocabulary and Subaru quality system conventions, so translated documents read as production engineers on both sides of the relationship expect them to read.
What German technical documents do you translate for Indianapolis aerospace programs?
We translate material and process specifications written against DIN and EN standards, component qualification packages from German Tier 1 suppliers, engineering calculation notes from German design organizations, EASA certification documentation submitted through German accredited design organizations, and collaborative engineering reports from joint programs with MTU, Liebherr, ZF, and Diehl Aviation. We return documents formatted to match the conventions of German aerospace engineering documentation rather than producing generic translated prose.
How do you handle confidential pharmaceutical documentation?
We handle all pharmaceutical client documentation under NDA, restrict file access to the named translators and project manager assigned to the engagement, transfer files only through encrypted channels, and maintain audit records of who accessed each file and when. For documents that include trade secrets such as formulation details or process parameters, we can implement additional controls including compartmentalized access where individual translators see only the sections relevant to their assignment. We do not process pharmaceutical content through any public or cloud-hosted machine translation engine.
Do you have an office in Indianapolis?
No. Techniwords is based in Texas and serves Indianapolis clients remotely, as we do clients across the country. File exchange is encrypted and portal-based, project managers work Eastern time hours, and quotes arrive within one business hour of upload.
