We have completed a generic questionnaire form which complies with most company’s requirements.

We believe that all your QA requirements for approving HSL as a quality supplier can be met from this section of our website. However, if you have any further specific questions to meet with your QA requirements please email them to Mark Panton.

HSL has already been approved by many of its airline customers via their QA audits and questionnaires. We are also an approved supplier to Westland Helicopters and Eurocopter.
