Equipment / Furnishings — Stretcher Trolley Installation — Modification
Summary
EASA Airworthiness Directive 2022-0122 is an airworthiness directive issued by the European Union Aviation Safety Agency concerning the installation of stretcher trolleys on Pilatus PC-24 aeroplanes, specifically those with manufacturer serial numbers 105, 106, 118, 169, and others modified by EASA STC 10067483 revision 2 or earlier. The directive addresses safety issues related to the mattress height below the left-hand Over-Wing Exit sill that could impede emergency evacuation. It mandates modifications to the stretcher trolley installation and updates to emergency procedures.
What Changed
This new directive requires replacing affected Cyrrus CI-2010-321-00 mattresses with serviceable mattresses having a different part number and modification placard. It also mandates updating the Emergency Instruction Card and amending the emergency evacuation procedures in the Flight Manual Supplement. The directive introduces these changes to ensure compliance with emergency evacuation requirements and improve occupant safety.
Why It Matters
For aviation professionals, this directive is critical because it addresses a potential safety hazard that could delay emergency evacuation and increase the risk of injury. Operators and maintenance organizations must ensure compliance to maintain the airworthiness of affected PC-24 aircraft and to meet regulatory requirements. Failure to comply could result in operating restrictions or safety risks during emergency situations.
What To Do
Operators of affected Pilatus PC-24 aircraft must replace the identified mattresses with serviceable parts, update the Emergency Instruction Card, and amend the emergency evacuation procedures within 60 days from 8 July 2022. After completing these modifications, installation of the affected mattress parts is prohibited. Compliance must follow the instructions in Aerolite AG Alert Service Bulletin ASB-22-004.
