Strategic MRO Selection & Negotiation
Case Study: Maximizing Leverage in MRO Selection
The Challenge
A client was facing high cost estimates for two engine shop visits with limited commercial transparency and complex lease requirements.
Our Approach
We performed an in-depth technical analysis of the engines and developed a tailored RFQ (Request for Quotation) with a refined workscope and scrap rate assessment. We then expanded the tender process to include our global network of qualified MRO partners.
The Results
- Engine 1: Maintenance cost reduced from $7.1M to $5.7M.
- Engine 2: Maintenance cost reduced from $7.2M to $6.0M.
Key Takeaway: Strategic negotiation before MRO selection is the highest leverage point for airline cost savings.
Case Study: Delivering Real Savings via USM Sourcing
USM Sourcing & Material Cost Optimization
MROs typically charge for Used Serviceable Material (USM) at approximately 70% of the Catalogue List Price (CLP), which often hides significant markups. Leveraging our global vendor network, we sourced equivalent airworthy materials directly from the market for mature platforms like CFM56 and V2500.

Strategic Quick Turn vs. Full Restoration
Case Study: The $5 Million 'Quick Turn' Strategy
The Challenge
Optimal Aero’s Analysis
The Solution
A Borescope Inspection (BSI) revealed damage to HPT NGVs. The airline was planning a full Performance Restoration ($10M+) as several years had passed since the last heavy visit.
We analyzed the remaining Life Limited Parts (LLP) lives, Time On Wing (TOW) projections, and lease return conditions (3 years remaining).
Instead of a full restoration, we executed a surgical 'Quick Turn' shop visit to replace only the damaged components and postponed the heavy restoration to align with the lease end.
The Results
- Direct Savings: Over $5,000,000 saved by eliminating unnecessary restoration fees.
- Asset Protection: LLP residual lives and Maintenance Reserve accounts were preserved.
- Strategic Outcome: Full compliance with lease obligations at a fraction of the originally projected cost.
