SPAES GmbH & Co. KG installed with KMN Koopmann Helicopter GmbH a deployable Emergency Locator Transmitter (automatic deployable-ELT) in helicopter airbus AS355 and AS350.
According to the new requirements of the European Aviation Safety Agency (EASA) for offshore operation, which are realised by the German Federal Aviation Authority (Luftfahrt-Bundesamt LBA), SPAES installed with KMN an automatic deployable Emergency Locator Transmitter (AD-ELT) at the lower fuselage of the airframe which is important for offshore operation. “In contrast to common standard transmitter, which are installed inside of the helicopter, this AD-ELT transmitter swims on the water in case of ditching and continues transmitting the location data”, explains Joachim Kies, Head of Operative Business of SPAES.
The operation and the manually dropping off will be achieved by an unit which is installed in the cockpit.
Furthermore the system has a water- and acceleration sensor. In case of a rigid impact or if water flows in the helicopter, the transmitter will be automatically dropped off.
The modification of the system was realized in the own maintenance organization of KMN. “An EASA Supplement Type Certificate (STC) was implemented for the installation. SPAES designed the required installation and test documents”, said Joachim Schanz, Chief Executive Officer of SPAES. The tests for the verification were realised on site with the customer.
