The aircraft are modernised regularly to ensure that they are technically up-to-date. DRF Luftrettung’s maintenance facility at Karlsruhe/Baden-Baden, which is EASA Part 145 approved, is operated by DRF Luftrettung’s own team of
expert technicians and highly qualified aircraft inspectors. It is here that the air ambulance aircraft are serviced,
repaired, modified and painted. In addition, technicians install devices such as navigation systems and mount medical equipment such as stretcher facilities and oxygen supply systems.

Some maintenance activities have been sub-contracted to different JAR or PART 145 organisations.

The following sub-contractors are engaged to support the current fleet of aircraft:

• Bombardier Learjet 35A Jet Aviation Flugzeugwartung Köln DE.145.0014
• Bombardier Learjet 35A Aero-dienst Flughafenstrasse 100 D-90411 Nürenberg DE.145.0011

Regular checks on the fleet are also carried out in compliance with aviation authority regulations and the manufacturer’s own guidelines. For the LearJet, these include comprehensive checks after 300, 600, 1.200 and 2.400 flight hours.

In addition, compliance with security standards is supervised by internal quality audits and by the Luftfahrt-
Bundesamt (German Federal Office of Civil Aviation) and by the Luxembourg Direction de l’Aviation Civile (Civil Aviation Authority) at the Ministry of Transport.

This allows a high fleet efficiency and thus ensuring safe transportation.
