What Most Operators Miss When Addressing Thrust Reverser Corrosion

Why the Right Repair Approach Matters

Improved corrosion protection on Challenger 300 and 350 thrust reversers is critical, but how that work is accomplished can significantly impact cost, downtime, and long-term flexibility.

Preparing for What the Service Bulletin Doesn’t Cover

At DAS Aviation, the focus goes beyond simply accomplishing the Service Bulletin. The objective is to deliver repair solutions that hold up when real-world findings do not go exactly as planned.

The Key Differentiator Most Operators Overlook

One key differentiator is approved data that allows the Service Bulletin to be performed more than once. This provides operators with long-term flexibility instead of locking them into a single-use solution, an important consideration as aircraft age and corrosion findings evolve.

In-House Engineering When Findings Go Beyond Limits

When components are found beyond published limits, DAS Aviation’s fully in-house engineering team enables rapid evaluation and compliant repair development without delays tied to outside engineering support. This capability allows localized damage to be addressed while avoiding unnecessary thrust reverser door replacement, reducing both cost and downtime while maintaining airworthiness.

Solving Location-Driven Maintenance Challenges

Operational flexibility is another critical factor. If an aircraft cannot remain at its current location, DAS Aviation supports fly-on capability, allowing repositioning to a more efficient maintenance environment and reducing AOG exposure. For operators focused on minimizing downtime, Challenger 300 thrust reverser exchange units are available to keep aircraft moving while repairs are completed.

Inventory That Protects Turn Times

Supply chain reliability also plays an important role. DAS Aviation maintains on-hand inventory of commonly replaced, hard-to-source hardware along with MAP Aero paint, helping protect schedules and avoid material-driven delays.

Experience That Reduces Risk

Supporting all of this is a team of highly experienced Challenger technicians, each with more than ten years of hands-on experience performing the thrust reverser Service Bulletin. This depth of experience reduces risk, improves quality, and ensures the work is done right the first time.

A Repair Partner When It Matters Most

For Challenger operators, the difference is not just completing the Service Bulletin. It is having a repair partner equipped to deliver practical solutions when findings go beyond expectations.
