EASA AD 2024-0075
Doors — Passenger Jettisonable Window Mechanism — Replacement
Summary
EASA Airworthiness Directive 2024-0075 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus Helicopters H160 B models modified by EASA Supplemental Type Certificate 10080809. It addresses the replacement of passenger jettisonable window mechanisms due to potential safety issues with the self-locking nuts and cable kits in the window jettisoning system. The directive mandates corrective actions to ensure the continued airworthiness and safety of the affected helicopters.
What Changed
This new airworthiness directive requires the replacement of affected passenger windows on Airbus Helicopters H160 B models with serviceable windows within 165 flight hours after the effective date. It prohibits the installation of affected passenger windows or doors containing them on any helicopter from the effective date onward. The directive introduces mandatory compliance with the MECAER Mandatory Service Bulletin SB-A6H-009 and the Vision Systems Service Bulletin 02-050-015 to address the unsafe condition.
Why It Matters
This directive is critical for aviation professionals because it addresses a safety risk where the window jettisoning system may fail, potentially preventing passenger escape during emergencies such as ditching or water impact. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and passenger safety. Non-compliance could lead to operational restrictions and increased safety risks.
What To Do
Operators of Airbus Helicopters H160 B modified by EASA STC 10080809 must replace all affected passenger windows with serviceable ones within 165 flight hours from 1 April 2024. Additionally, no affected passenger windows or doors containing them may be installed on any helicopter from the effective date. Maintenance teams should follow the instructions in MECAER MSB SB-A6H-009 and Vision Systems SB 02-050-015 for the replacement and modification process.
