There are three series of modifications for the Bulldog:

BH Series – This is the main series of modifications approved under civil regulations, with applicability across more than one Model.

BCR Series – This is the ‘Bulldog Customer Requirement’ series of modifications which may be applicable to one Model only. Typical modifications in the BCR series introduce variations of avionic and military equipment fits.

T Mk 1 Series – Separate to the BH and BCR series of modifications, the Royal Air Force developed its own series of modifications to meet its own specific requirements for the Bulldog T Mk 1. These modifications were approved under military airworthiness regulations and are not automatically applicable to civil-registered aircraft; however, many T Mk 1 modifications have subsequently been approved within the BH series.

The various indexes of Bulldog Design Authority Modifications are available at PDF Downloads. Further information, including Modification Leaflets where applicable, is available from DHSL.

Please note that our archive is unlikely to contain details of modifications raised independently of DHSL or its predecessor Type Design Organisations. Such modifications may also be proprietary to their originators.

Service Bulletins and Service Letters

Instructions for continuing airworthiness may be published as Service Bulletins and Service Letters, which may be given mandatory status by a National Aviation Authority. Bulldog owners and engineers must refer both to SB and SL and to the Aircraft Servicing Manual, and should read one in conjunction with the other.

The index of current Service Bulletins and Service Letters is available at PDF Downloads.

In view of its airworthiness significance, the current issue of Bulldog Service Letter BDG/1/2004, for the management of Bulldog airframe Fatigue Index, is also available as a free download.

We stock an expanding range of recent new manufacture Bulldog airframe components, and will in the future have available kits for Bulldog modification BH193, the main spar reinforcement. A new buy of Bulldog engine air intake filters is in course of manufacture. All new parts are supplied with approved release.
