Protect your Investment with an Extended Warranty
Your White Lightning M1428-DV is built to deliver years of dependable service powering your aircraft's electrical systems during maintenance, avionics updates, and preflight operations. An Extended Warranty gives you additional peace of mind after the initial one-year standard warranty coverage ends.
Protecting the equipment you rely on helps minimize unexpected repair costs and keeps your operations running smoothly.
Just like the original one-year warranty, this extended warranty provides full coverage of your GPU for an additional one-year period from the time of purchase.
How our Extended Warranty program works:
- Activating your Extended Warranty requires you to register your GPU purchase for tech support. Warranty service eligibility is tracked by serial number ownership, so if you have not yet registered your GPU, use this link to do so: Product Registration: https://whitelightninggpu.com/pages/gpu-product-registration
- Once registered, we will send a warranty coverage verification label to affix to your GPU with the expiration date (see below image). Should your GPU require service, this label will quickly identify it upon arrival for priority service with our tech support team.
- Your Extended Warranty may be renewed annually prior to the expiration date to ensure continuing protection. A new warranty verification label will be provided at each renewal with the new expiration date to replace or cover the expired one.

What's Covered?
Our Extended Warranty continues protection against defects in materials and workmanship beyond our original warranty period. If a covered issue arises during normal operation, we'll repair or replace your unit according to the terms of the warranty agreement.
