Background

The certification of the propeller ice protection system involves an overlap between airplane and propeller requirements. The airplane is required to meet the icing requirements of parts 23 or 25, whereas the propeller is required to meet the applicable structural and durability requirements of part 35. This overlap in certification requirements between two certified products, airplanes and propellers, has led to confusion over the configuration and quality control responsibility for the certificate holders. For example a deicing system shown on a propeller type certificate data sheet does not mean that compliance with part 23 icing requirements was shown.

This proposed policy provides guidance for compliance with parts 21, 23, 25, and 35 of Title 14 of the Code of Federal Regulations. The proposed policy clarifies configuration and quality control responsibilities for certificate holders and parts suppliers involved with propeller ice protection systems. This proposed policy does not create any new requirements.
