H4 Aerospace Ltd has been operating as an EASA DOA now for close on 20 years and following Brexit, is now a UK CAA DOA. H4 employs up to 25 engineers and support staff across the UK . H4 can also provide support engineers during the installation phase of one of our modifications if required.

The experience built up over the 20 years in business and with the staff employed, has enabled the H4 Aerospace DOA Scope of Approval to expand to cover most modification requirements for airline and VIP operators.

The H4 Aerospace’s head office is situated in Hemel Hempstead, Hertfordshire.
