Disclaimer or limitation of warranties: unless prohibited by applicable law, and except for the limited warranties set forth above, Hartzell hereby disclaims any and all express and implied warranties, including but not limited to implied warranties of merchantability and fitness for a particular purpose. In the event disclaimer of implied warranties is not permitted under applicable law, such implied warranties, including but not limited to implied warranties of merchantability and fitness for a particular purpose, are limited in duration and in scope of coverage to the duration and scope of coverage of the limited warranty. Some states do not allow limitations on how long an implied warranty lasts, so above limitation may not apply to you.

Terms and conditions of limited warranty coverage: in order to obtain coverage under Hartzell’s limited warranty, the purchaser must notify Hartzell in writing of the warranty claim as soon as possible after obtaining knowledge of the potential claim, and in any event not later than ten (10) days following expiration of the limited warranty. Hartzell may withhold warranty repairs pending proof from purchaser of the date the product was placed into service, including a copy of the invoice and installation log book entry. Hartzell shall provide warranty repair or disposition instructions based on a written statement from the purchaser describing the alleged defect. All initial transportation and handling charges must be prepaid by the purchaser until warrantability is determined by Hartzell, at which time Hartzell may reimburse none, some, or all of these charges, at Hartzell’s discretion. In the event Hartzell determines, at its sole discretion, that the product or component thereof is covered under the limited warranty, Hartzell shall, at its election, either: (1) have the product or component repaired and returned to purchaser; (2) deliver to purchaser a replacement product or component; or (3) issue a credit in the amount of the actual price paid to Hartzell by the distributor that purchased the product. Hartzell reserves the right to replace products or components with overhauled or re-designed products or components of substantially equivalent quality. All warranty repair work will be accomplished at Hartzell’s principal place of business, or a third-party location pre-approved in writing by Hartzell. In the event Hartzell determines that the alleged defect is not covered by the limited warranty, the product or component will be returned to purchaser, as is, transportation and handling charges collect.

The only remedies under this limited warranty are as set forth above. Any Product repaired, or replacement Product provided, shall retain the balance of the limited warranty provided for herein. This limited warranty is not transferable to any person or entity. This limited warranty does not extend to future performance of a Product.

These disclaimers are independent of any failure of the essential purpose of any warranties or remedied provided to purchaser, and shall survive any determination that a warranty or remedy failed of its essential purpose.
