A330 Installation Certification Mobile Crew Rest

In cooperation with our customers: Zodiac Aerospace and Aerolineas Argentinas, Sii Netherlands last year completed an STC installation of a Lower Deck Mobile Crew Rest (LD-MCR).

After a challenging major change or STC certification process the EASA approval was granted end of 2017. The subject of the STC was the installation of Zodiac Aerospace LD-MCR, in the forward section of the rear cargo compartment in two A330-200 aircraft. The operator was supplied with the required certification documentation, installation and test instructions for the installation of the LD-MCR.
