MRO Engineering for the World's Most Demanding Aviation Programs

From airframe maintenance and engine overhauls to structural repairs, component teardowns, and fleet-wide modifications. Indvaltech brings engineering precision to every stage of the MRO lifecycle.

MRO Solutions

Eleven engineering services across the maintenance lifecycle

Each engagement is owned end-to-end by a dedicated engineer and delivered with full substantiation and traceability, ready for your quality and airworthiness review.

01

Engineering Verification and Validation

Independent review of designs, repairs and modifications against airworthiness requirements, confirming every change is substantiated before it reaches the aircraft.

02

Remastering

Re-creation of legacy 2D drawings and obsolete data into clean, parametric 3D models and controlled, manufacturable drawing packages.

03

Repair Instruction

Development of structural and component repair instructions, SRM-aligned, with the full engineering substantiation behind each disposition.

04

Engineering Authorization

Preparation and disposition of engineering authorizations for non-conformances, deviations and in-service findings.

05

Supplements, Addendums and Service Bulletins

Authoring of manual supplements, addendums and service bulletins that keep technical publications current and compliant.

06

Design Improvement

Reliability- and cost-driven design changes that extend component life and reduce the maintenance burden in service.

07

Airworthiness Documentation Support

Compilation of substantiation packages and compliance records supporting certification and continued airworthiness.

08

ERP Entry

Creation of work instructions, stock codes and bills of material: structured, validated data ready for production planning.

09

Design Validation through Engineering Analysis

Structural, fatigue and thermal analysis (FEA) to validate repairs and modifications before they are implemented.

10

Weight and Balance Report

Calculation and reporting of weight and balance impact for modifications, repairs and configuration changes.

11

Tear Down Report

Structured documentation of all findings from component disassembly, covering condition assessments, damage identification, measurements, and disposition recommendations to support repair and overhaul decisions.
