EASA AD 2025-0225-E
SUPERSEDED BY EASA EMERGENCY AD 2025-0230-E
Summary
EASA Airworthiness Directive 2025-0225-E is an emergency directive addressing the inspection and replacement of turbocharger and intercooler hoses on Textron Aviation Inc. Model 182M through 182R and Reims F182P and F182Q aeroplanes equipped with SMA SR305-230 engine installations under EASA STC 10013975. The directive targets specific intercooler inlet/outlet hoses identified by part numbers SP01170459-0, SP01170385-1, SP01170460-0, SP01170386-1, 1500004183-1, and 1500004182-1. It mandates inspections and replacement to prevent engine power loss due to damaged hoses.
What Changed
EASA Airworthiness Directive 2025-0225-E introduces mandatory repetitive inspections of affected intercooler hoses at intervals not exceeding 50 flight hours and requires replacement of any damaged hoses before further flight. It also establishes a life limit of 500 flight hours for these parts, requiring their replacement before exceeding this limit. This directive is a new emergency action and does not supersede any previous AD.
Why It Matters
This directive is critical for aviation professionals because damaged intercooler hoses can cause loss of manifold pressure and engine power, potentially leading to forced landings and safety risks. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and prevent in-flight engine failures. The directive’s interim nature indicates that further regulatory actions may follow, requiring ongoing attention from compliance teams.
What To Do
Affected operators must inspect the specified intercooler hoses before the next flight after 20 October 2025 and continue inspections every 50 flight hours thereafter, following SMA Aero Engines Service Bulletin SB-C182-71-011. Any damaged hoses must be replaced with serviceable parts before the next flight. Additionally, all affected hoses must be replaced before reaching 500 flight hours since first installation. Installation of affected parts is only allowed if they meet the serviceable criteria defined in the directive.
