Many factors, such as storage conditions or the opening and resealing of the original container, can affect shelf life of de-icers. As a rule, de-icers should be used “on condition,” regardless of age. The term “on condition” means there is no set shelf life on Collins Aerospace Goodrich® de-icers; however, after a storage period of 60 months from the cure date, the factory warranty begins to expire and an inspection may be required prior to use. To ensure full on-wing warranty is attained, installation is recommended prior to the end of the 60-month timeframe. After the warranty expires, the deicer can still be deemed airworthy and installed through inspection in accordance with Goodrich® ATA 30-10-31.
The cure date of the de-icer, which is the date of manufacture, can be found on the original box as well as the de-icer laser brand (shown below), which is typically located on the lower inboard edge of the de-icer.
If stored correctly, Collins Aerospace Goodrich® deicers can remain in a serviceable condition for many years beyond the warranty period. De-icers should be stored in the original box and heat-sealed bag in a dry place at temperatures between 40-80°F (4-27°C).
On-wing factory warranty timeframe is as follows:
