QM-01 Quality Manual

Revision F · Effective 2025-11-03

1 Purpose

This manual describes the quality management system (QMS) of Tallgrass Precision Components, Inc. It states the quality policy and quality objectives, defines the scope of the QMS and its one exclusion, and shows how the quality procedures (QPs) fit together. Detailed requirements live in the QPs and work instructions cited below; this manual does not repeat them.

2 Scope

2.1 Sites

The QMS covers the Wichita plant (Bays 1 through 7) and the sales office in Overland Park, Kansas. The Overland Park office performs quoting, contract review and customer communication only; no product is stored, handled or inspected there.

2.2 Products and services

Tallgrass provides CNC machining and precision mechanical assemblies to customers in the aerospace, defense and medical markets. All work is build-to-print against customer drawings, models and specifications.

2.3 Certification basis

The QMS is certified to AS9100D and ISO 9001:2015. Certificates are posted on the Quality SharePoint site.

2.4 Exclusion

AS9100D clause 8.3, Design and development of products and services, is not applicable. Tallgrass does no product design; customers retain design authority and all drawing or specification changes come from the customer.

3 Quality Policy

Tallgrass Precision Components builds parts and assemblies exactly to our customers' requirements, delivers them on time, and keeps improving the way we work. Every employee is responsible for the quality of his or her own work and has the authority to stop work when product or safety is in doubt.

The policy is approved by the President, posted at each bay entrance, and reviewed for continuing suitability at every management review. Awareness of the policy is part of new-hire orientation under QP-6.2.

4 Quality Objectives

4.1 Company-level objectives

Objective	Target	Measured
On-time delivery to customer promise date	>= 96%	Monthly, from ERP ship data
Customer reject rate	< 500 PPM	Monthly, rejected pieces per million pieces shipped
Internal scrap cost	< 1.5% of sales	Monthly, scrap NCR cost from the ERP divided by net sales

4.2 Reporting

The Quality Manager publishes the objective results monthly on the Quality SharePoint site. A target missed for two consecutive months is reviewed at the next monthly quality metrics meeting and may result in a corrective action under QP-8.5.

5 Organization and Responsibilities

5.1 Top management

The President, Margaret Lindqvist, has overall accountability for the QMS, approves this manual and the quality policy, and chairs management review.

The Production Manager, Engineering Manager, HR Manager, IT Lead, Shipping & Receiving Lead, Contracts & Export Compliance Manager, EHS Coordinator and Controller are each responsible for the processes in their areas, for training their people to the training matrix, and for supporting audits and corrective actions.
