Maintenance & Modifications

Designing the Future of Aviation

Bristow provides technical support services, maintenance and modification to the global helicopter industry. Whether supporting our global fleet or transforming third-party concepts into reality, the Bristow Design Team works collaboratively with all our customers designing and certifying modifications to comply with the stringent numerous regulatory jurisdictions and environmental requirements.

For more than 65 years, Bristow has continued to develop groundbreaking systems to meet the demands of any operational aircraft and any flight operation, across all continents. Numerous innovations have been produced over the years, many of which have since been adopted by the regulatory authorities or by the Original Equipment Manufacturers (OEM) as industry standards. This has led to several OEM commissioning to develop safety systems that are incorporated into production line aircraft.

Design and certification disciplines cover avionics, mechanical installation, structures, stress analysis and full technical publications.

Below is an example of a small number of our design achievements: 

Technical Services in conjunction with Rockwell-Collins has developed, certified and embodied TCAS II on AS332L1, EC225, S-92A and S-76 aircraft.
