What to do
Operators of PS-28 Cruiser aeroplanes with Rotax 912 ULS2 engines must perform a visual inspection of the valve push-rod ball sockets within specified flight hour or calendar time limits, depending on engine usage. If wear or black surface is detected, affected valve push-rods and related parts must be replaced before the next flight. Installation of valve push-rods manufactured between 01 May 2016 and 02 October 2017 is prohibited unless verified otherwise.
Summary
EASA Airworthiness Directive 2017-0242 is a corrective directive addressing the inspection and replacement of valve push-rod assemblies on Czech Sport Aircraft a.s. PS-28 Cruiser aeroplanes equipped with Rotax 912 ULS2 engines. It targets valve push-rod assemblies manufactured between 01 May 2016 and 02 October 2017 due to potential wear that could cause engine power loss and rough operation. The directive mandates inspection and, if necessary, replacement of affected parts to ensure continued airworthiness.
What changed
EASA Airworthiness Directive 2017-0242 introduces a one-time inspection requirement for valve push-rod assemblies on affected PS-28 Cruiser aeroplanes and prohibits installation of valve push-rods manufactured during the specified period. This document republishes the directive to correct the ATA Chapter number and clarifies compliance instructions. It builds on previous directives related to BRP-Rotax 912 and 914 engines by extending requirements to the aeroplane type design.
Why it matters
This directive is critical for aviation professionals because it addresses a safety issue that could lead to engine power loss and forced landings. Operators and maintenance organizations must ensure timely inspections and replacements to prevent engine malfunction and maintain regulatory compliance. Failure to comply could result in unsafe flight conditions and regulatory penalties.
