Budget and Build Plan

Delivering a UK-built Mosquito

As we recently announced (in March 2018), analysis of a wealth of original de Havilland technical data has enabled the project to take the momentous decision to rebuild our Mosquito FB.VI in the UK.

After careful consideration, in early 2018 the board approached Guy Black, Director of Retrotec Ltd – one of the world’s most widely respected heritage aviation restorers in the world – to discuss our plans. Retrotec’s proven track record of restoring wooden airframes is complemented by the fact they are fully certified by the UK Civil Aviation Authority – smoothing the way to eventual airworthiness acceptance.

Thanks to Guy and his team’s exceptional skills and our technical data, we expect the vast majority of work to be completed in the UK, providing our supporters – both individuals and companies – with the chance to see, smell and even touch the aircraft as she takes shape.

As this project relies heavily on donations, both small and large, the timescales to bring RL249 need to be updated regularly. For the latest updates on fundraising, be sure to sign up for our newsletter – The Buzz (available via the TPM homepage).
