Civil aircraft maintenance
In accordance with Part 145 and Part M of the European Aviation Regulations maintenance, overhaul and major repairs of civil aircraft have to be done by companies are approved as maintenance organization for developing, manufacturing or Continuing Airworthiness Management Organisation.
According to these requirements, our company is certified as a Part 145 Maintenance Organisation No. DE.145.0272 and as a Continuing Airworthiness Management Organization No DE.MG.0272 acc. Part M of the EASA.
Part 145 Maintenance Organisation Approval
The AEROCONCEPT engineering company for aviation technology and composite technology was first certified on 3 June 1994 by the LBA as an aeronautical maintenance organization No. II. A 276. The recognition initially included all airworthiness reviews after major changes, overhauls and major repairs of motor gliders and gliders in wood, tube and fabric and fiber-reinforced plastic construction.
On June 11th 1996 the scope of recognition was extended to the review of components and assemblies in FRP construction of aircraft with a maximum take-off weight up to 2 tons for major changes, overhauls and major repairs. By moving into the new building on May 29th 2001 the company finally got its approval No. LBA.0272 as maintenance organization according to the Joint Airworthiness Requirements (JAR) 145.
This approval allows us to review all parts and components in FRP design in all European civil aircraft and to attest its airworthiness.
As part of the transition from the Joint Aviation Authorities (JAA) to European Aviation Safety Agency (EASA), our company got the approval of maintenance organization in accordance with Part 145 in 2004.
Approval as Continuing Airworthiness Management Organisation
Since march 2009 the AEROCONCEPT GmbH has also been recognized as a Continuing Airworthiness Management Organisation acc. Part M. After the transition from national aviation rules to European rules has taken place, this allows us to determine the airworthiness and to issue the relevant documents for the continued operation of the aircraft (Airworthiness Review Certificate).
The company is aiming for an additional approval as manufacturing and development company in the future.
Large changes in aircraft
Besides a variety of major changes to gliders and motor gliders AEROCONCEPT was able to acquire several interesting jobs in the sector of "Major changes in aircraft with take-off weight exceeding 20 tons" since its approval of JAR 145.
For example, in cooperation with the Aviation Center Cologne, the complete upper rudder fairing of a Challenger 604 jet, originally made from CFRP, was replaced by a glas-carbon-fiber reinforced plastic (CGFRP) structure. This measure was necessary to ensure the proper function of the retrofitted satellite communication system's antennae. The moulds for this project were built by our company, too.
Another order placed was for a "major change" of a Bombardier Aerospace Global Express BD700 in cooperation with the Aerodata Systems GmbH and the Dynatec GmbH.
In spring of 2002, a first aircraft was modified to carry equipment for high-precision calibration of an instrument landing system at airports for the Japan Civil Aviation Authority (JCAB).
All modifications of the affected composite parts, including building the required moulds and tools, have been done within a narrow time span. Since the expectations of the customer were fully met, a second order for modifications on a Global Express was placed in may 2002.
Major repairs on aircraft structures
Besides the prototype manufacturing of aircraft components, we have relevant know-how in the repair of composite structures.
"Major repairs" on gliders, powered gliders, powered aircraft and commercial aircraft are currently our dominant line of business. We are able to repair structures made of glass fibers, carbon fibers, aramid fibers, dyneema fiber or hybrids thereof. All these repairs are based on the repair and maintenance manuals of the manufacturer (Structural Repair Manuals, SRM, and Maintenance Manuals, MM).
Especially in unplanned maintenance (aircraft-on-ground events, AOG), we provide exceptional flexibility. Due to the immense cost of an aircraft bound to the ground, a high range of flexibility as well as zero-error tolerance is generally the request of our customers. A demand AEROCONCEPT was always able to fulfill.
