Identification of issue
EASA was made aware of minor changes to install Cargo Seat Bags on passenger seats in order to conduct flights for transportation of mail and/or cargo.
A Certification Memo EASA CM – CS – 003 Installation of “Cargo Seat Bags” on Passenger Seats was issued on 14th Nov 2012 requiring application for major modification or STC.
EASA recently received an application for a STC and therefore started the process to issue applicable Special Conditions.
While this is the first application the conditions prescribed below are linked to the project and any future application may require new or revised conditions.
Since this installation of Cargo Seat Bags is a change in the scope of operation of the aircraft, and in the absence of operational requirements covering this kind of operation, the installation and the procedures for operation have to be addressed taking into account the specific configuration of each aircraft model affected.
While the certification bases for the aircraft models affected by the change may vary the configuration of the aircraft cabins modified for transportation of mail shall conform to a minimum standard with respect to the affected parts of CS-25.
